I have a set of objects each associated with a connection The object only contains a channel and an Integer field
can anyone look at this and tell me why a ParseException is being made?
http://pastebin.ca/647375
I can’t see any reason why the SimpleDateFormat class cannot parse that string, but for some reason it gives an ParseException
how are you passing the date in the string?
eh?
nevermind
hadn’t looked at code yet
lol, you got the pastebin then
g[r]eek: turns out that if I set the locale to new Locale(“en”,”GB”) instead of Locale.getDefault() it works fine
my locale here is spanish, I think maybe it has a problem with this date format
must be.
i have no clue otherwise
in addition, because the month Aug, does not match the locale settings abbreviation for August, in Spanish, August is Agosto, it doesnt parse correctly
oh well there’s the cause then
well spotted
waht does getAvailableLocales() give you
mmm, this wss4j project for ws security is little out of date, isn’t it?
hmm?
i’m checking Mule’s security… it uses WSS4J
I think nobody uses that anymore…
ah. are you a committer?
he, no
popular project i must say
wss4j?
oh crap. i read emule
my bad
and i was sitting here scratching my head wondering why you’d need wss4j with emule
maybe its because axis2 now has its own wss implementation
yep, and CXF also…
app server?
“Axis2 comes with a module based on Apache WSS4J [1] to provide WS-Security features, called “Rampart”"
yes
ah, jboss i presume
ah, jboss host i presume
hey cut it out

Exception ApiException is not compatible with throws clause in Object.toString()
can someone help me please?
hi, i’ve an issue. i created jList1 via Netbeans, everything is fine except one – my problem is that each row is small – height about 2milimetres… i tried to set up bigger font, but it didn’t help… how can i make “bigger” rows?
test case in pastebin?
~tell gothicNafik about test case
gothicNafik, Provide complete, compilable Java SOURCE CODE that shows the problem and nothing else. Be as brief as possible. (See http://javafaq.mine.nu/lookup?364 for details and a HOWTO.)
ok, i will paste it on a web…. give me a second
bbl
~pastebin
http://eugeneciurana.com/pastebin
ResourceBundle.getBundle(“../../Hello”); finds Hello.properties fine, but “../../foo/Hello” doesn’t find foo/Hello.properties.
http://eugeneciurana.com/pastebin/pastebin.php?show=3501 starting on row number 130
yikes, that is not nice-looking code…
no comments? what is this class supposed to do?
too long lines, that paste has lots of extra line breaks in it …
you do not close your readers in a finally-block
my eyes! the googles! they do nothin!
your indentation seems broken at line 136
a test case should not be in a package, it just complicates testing by others.
when I run that class the jvm exits directly
did you try that code yourself?
compilation and build is ok
yes, the code compiles, but with an empty main(…) it will not do much
And classes should start with a capital letter
gui.Main();
according to sun:s java code standard. You do not have to follow it (but I do in this regard)
program works fine, except that small rows
Exception ApiException is not compatible with throws clause in Object.toString() — how to handle that
that your method names are not english does not help, reading your code is not easy for me…
Sure, you don’t _need_ to follow it. But if you don’t (and mix both english and someLangeuage in looong lines) help is a lot harder to get here, imo. At least from me.
Hmpf. You beat me to it
when I add a Main() call in main(…) I get a window, with two white boxes, the left has a tree with one root and two nodes
i am sorry about that, next time i will write all in english
agreed
yes
but I myself do not follow the sun code guide regarding ‘(‘. I always put a blank before it (and make sure my pre-commit hooks checks for it)
and the second one (on the right side) is jList
but that jList has very small rows
the right contains nothing.
it is about 3 cm heigh
you are not right, jList1 contains data
could be because I do not have the valhala-data directory?
damn. I can’t make toString() function throw my own exception?
lines 130-134
No
you can make it throw a RuntimeException, but not a checked one
(or subclass of RE of course)
i can see rows in jList with text… that’s everything fine… i just want to make take rows bigger
on height
provide a test case that works for more people and do not depned on files that only exist on your hard drive
setFixedCellHeight() ?
g[r]eek: and this is method of jList?
g[r]eek: that is not the problem…
Neither do I (following the guideline completely). But a common base for “code that I want others to look at” is really needed and sun is closest here, imo
that setFixedCellHeight() works, thank you
maybe, but I do not care much as long as the code is using only one style guide
blank before ‘(‘ everywhere, including method calls?
yes
“new Foo ()” as well as “fooFactory.newInstance ()”
yuck
that was what I used in C/C++ a long time before I started doing java….
why should I think about what is a constructor/if/for/… or a method call
I’ve never had to think about it

so HA HA HA
the shooka’s are before the hammond. neener yerself.
o_O
shooka? Oh, the shakers
it made me think of “sound chaser”
that series of albums from Yes ranks among my favorites
Going for the One
yah, the shakers are in the first few versus, behind the dittit-dittit parts.
you listen to radioparadise?
mmm
erm… no bells ringing
ah, you should. you’d like it.
http://www.radioparadise.com/
I’m listening to Arcade Fire a lot lately, though, which is very uncharacteristic for me and thoroughly enjoyable
I’ve been meaning to pick up tormato and topographic oceans, just to round things out
tormato and oceans are just too indulgent for me… after Going for the One, Yes kinda went “no”
90125 and Big Generator were good, but they weren’t really YES
one thing RP does is you can rate a song as it comes along. look at my ratings here – you get an idea of the sort of stuff they play:
http://www.radioparadise.com/content.php?name=Members&file=userinfo&u=12619
yeah, I actually have a separate classification in my ipod for Rabin’s Yes
Drama was OK iirc
I don’t have that one either
Drama wasn’t yes either… sorry, without Jon Anderson it ain’t yes
that article by weiqi gao… what a load of carrots
yeah, it was mostly the buggles iirc
the buggles with squire and white
ever listen to Anderson Bruford Wakeman and Howe? (yes-not-yes) ?
and rabin’s yes… it was sort of like what someone with a hell of a lot of skill would imagine Yes as being had they never heard it
g[r]eek:
yes
eidolon, yeah – my favorite bassist (tony levin) played with them
yes, THAT group rocked… all they needed was to replace Levin with Squire and you’d have had Yes… and since Howe was the driving force behind Yes anyway, it was closer
but yet – they were kinda so-so
Bruford was playing an electronic kit.. I never enjoyed that much
all hail bill bruford.
yeah it sounds really… artificial
so if you’re a classic Yes fan, I highly recommend Spocks Beard.
It’s wierd, for a band that was supposed to be so far ahead technologically, Yes really wasn’t all that brilliant on the effects/synths front
but I do listen to the resultant live album quite a bit
Pink Floyd was the same way
they didn’t need to, and thank goodness for that. their ahead-ness was in arrangements and pure unadulterated skill.
for all their reported brilliance as technologists, they relied on the farsi organ a hell of a lot
gonna have a hard time finding any better series of musicians than squire, how, anderson, and bruford
howe.
is that a new java lib?
I saw the last tour though, they had the “classic” lineup again
was excellent
Rush has gotten more technologically reliant mostly because the arrangements finally went into eight-musician territory, which three musicians just couldn’t do live
brb.
yeah
hrm. must’ve stumbled into ##oldmusic by mistake.
weird.
damn mondays.
lol
the “ladder” tour was so bad that I almost didn’t go this time but I’m glad I did…
bthe “ladder” tour was so bad that I almost didn’t go this time but I’m glad I did…/b
and that’s all I’ll say about that
the House of Yes recording was really good.
somebody must have a case of the mondays 
and I liked the Homeworld track… the rest… bleh
i have a case of the idontwannaworks
but that’s kinda my feeling for all Yes post-BG
“Talk” was at least as good as BG imo
You know, I haven’t heard Talk
~fap cheeser
Is that sad?
pick it up, it’s quite decent
right, so, here ya go. classic music that was ahead of it’s time, IMHO
Moody Blues – Question
rabin actually tried to get wakeman for it, but there was some contractual problem
yeah, wakeman and contracts have never worked out
for such a wanker, MAN was he awesome in concert
yeah…
brilliant
but he caused more problems for Yes than anyone else has
put the band into bankruptcy when he JOINED
they’re supposedly touring again next year
40000th anniversary or some such
only 40000th?
have you guys ever coded/designed a system and then when its just about ready to goto production you realize that you coul dhave improved on it with just some more time?
I hear they’re the reason that Java went with a “long” for timestamps instead of an “int”
almost every time
no, if that was the reason, java would have had long longs
ug im having to rush to get this system out and now im wishing i had more time to revamp some things =\
Aradorn, don’t worry about it – if it meets the requirements, it’s as good as it needs to be
yeah
learn for next time
its 10000 times better than the previous version
ive completely rewritten it in about 4 months
g[r]eek: that weiqi gao post has gotten me a lot of flack
i’m not surprised.
it’s funny for me, because people didn’t get what I was actually saying
i figured you were saying “don’t hire this guy. anybody. ever.”
changes are weiqi himself missed it
g[r]eek: what’s funny is that weiqi is a really bright guy
is there a simple stringy object/method for string substitution like “hello %name%, how are you on this lovely %day% ?” or something similar. in .NET and ol’ C it’s prety easy.
yes
that’s what i like about publishing an article on tss. it can either make or break you. if it makes you however, then what a way to earn a rep
g[r]eek: yeah… although a large part of me frets about what I’m doing to myself and my future employment possibilities
hehe
what’s the name ?
PrintWriter
perhaps a tad taboo, but what are your thoughts on infoq
jottinger thanks i’ll javadoc it
pm welcome
g[r]eek: *shrug* not taboo, I think it’s good for what it is
I think it has some fundamental challenges ahead of it, many of which I think the cult of personality will help evade
but I hope – for Floyd’s sake – he never loses that cult
bbut I hope – for Floyd’s sake – he never loses that cult/b
i guess that’s your experience in these matters talking. from my point of view, all i see is a jack-of-all-trades attempt with one helluva interface
g[r]eek: you like the interface?
you should be a fly on the wall for floyd’s and my conversations
yes. that’s not to say i think it’s superior to tss’s.
we’re good friends, of course, and I plan to keep it that way
g[r]eek: InfoQ’s interface is WAYYYY better than TSS’
I’m terrifically glad infoq is there, it’s helping drive the TSS rewrite
and yes, there is one
So you are spending all your spare time rewriting the TSS interface?
I’m working on a final revision of the requirements doc today, in fact
god no
tss’s does it’s job well. infoq’s is more web2.0′ish
g[r]eek: for our audience, we need web 2.0-ish
the average TSS reader considers himself ahead of the curve (like all drivers, they consider themselves to be above average) and they expect their tech sites to be ahead too
but like i said, i like that fact that tss is java full stop.
g[r]eek: *nod* that’s likely to change slightly… but we’re never going to abandon the platform
has bitten off a big chunk…
the language and platform are changing too rapidly for us to stay just java (language and platform)
lets hope they chew well.
we’ll slowly integrate groovy, ruby, python
g[r]eek: infoq allows you to filter out some of the ocntent yo migh tnot wat though, doesn’t it?
g[r]eek: They’re not doing what they’d like to do, I think
only with coarse filters
sure, that’s what makes their interface great
interesting i’ve never really given the filter an in-depth analysis. i don’t bother much with non-java material
how do I read from an URL if I’m behind proxies?
http://java.sun.com/docs/books/tutorial/networking/urls/readingURL.html
for a tech media company, our technical acumen blows
there is a company behind TSS?
is tss your full time job?
however, after the error messages, I do get the contents
g[r]eek: yes, among others
kids?
yes
g[r]eek: and other consulting
Rod Johnson actually asked me how I found time
hmm, I never knew.. not that it changes anywathing..
Well, it does, in some ways
Heh. That’s putting it mildly
i like the idea of making a living from managing a popular news board / blog
we’re backed by a huge media company, which is good and bad… good because we have funds to push forward, bad because it’s a media company and not a tech company
[TechGuy]: putting what mildly?
Having a media company behind you is good and bad
[TechGuy]: ah, yeah
well, having a three-year project shut down due to requirements – when you have domain experts in house and screaming to let them help – is baaaaaaaad
been there, done that
some of the questions I managed to get were staggering
they were planning on using a JCR product… and pondered using an in-house search library or google
nice
(for the illiterati, JCR includes – and mandates – a full-text search solution.)
they also wanted to avoid ajax because it wasn’t seo-compatible
Yeah, we’re going to use JCR, on top of Hibernate, with Lucene
heeheheh
that’s probably my only fear in growing my software company – reaching the stage where it’s not longer simple to redesign something / enjoy a good hack. bureaucracy is a necessary stench
*no longer
g[r]eek: well, the key is to keep your business’ goals in mind
My business goal? Get big. Make money.
Interface21 uses drupal, for example, which is PHP
goal #1 – no employees
mmm, drupal.
I blasted them for that, but their response was correct – their goal isn’t to use java, it’s to use something that works
that said, Rod’s remembered that I said that for years now… and he brought it up last time we met
hi. im stuck
mostly because SOMEONE mentioned backing TSS with cakePHP (not me)
get some lube.
breath in, and try to move.
breathe out surel
who designed the infoq interface?
inside toString i’m throwing checked exceptions..
g[r]eek: floyd, I think…

Don’t do that then

would developing a locally focused (why bother competing with the big guns) add value and what sort of content would be necessary?
where do i put the applicationContext.xml, web.xml, xfire-servlet.xml; normally they go in war/WEB-INF/ but in this case mvn is looking for it in /home/username/workspace-3.3.0/ApplicationName/target/ApplicationName-0.0.1/WEB-INF/web.xml which gets wiped on every mvn clean
a locally focused… missing noun?
ernimril, http://rafb.net/p/FznwLr39.html
erm, yeah, i meant to say something along the lines of “focused on local happenings” as opposed to internationally viable
that does not say anything?
Narada put resources in project/src/resource under mvn
src/main/webapp/WEB-INF
g[r]eek: I’m still missing a noun… you mean a locally focused site?
ernimril, i need some format in toString
Wha… *anyone* can tell the bot to leave?
resources even
[TechGuy]: don’t ask me, I didn’t code the damn thing
*doh* yeah, a site
ernimril, i’m checking if the values of the fields are set or not
like a mini-tss – a place to share technical articles and the like
g[r]eek: I dunno, it can be useful, you just need to be aware of what people in your area need
ernimril, if not append NOTSET.. otherwise append value.
using toString and expecting it to do what you want is not good, if you need a method that returns a string that is well formed, then add a getWellFormedString() in some interface and make your class implement that interface
BTW, l10n is one of the requirements for the new TSS
[TechGuy] yeah…. The author frequently gets asked to leave too.
and pass the more popular ones upstream to your site etc
Do that in the constructor or whereever you create the object.
umm is it src/resources or src/main/webapp; i’m getting conflicting answers
this is a service not a webapp; do i still need to put it there
resources.
Hi, Is there a channel for JSTL or is this one good for that too?
Throwing an “I don’t have X, so I’m useless” exception in toString() is quite – nasty. Stupid?
Maven in fascist about some things.
like it would be interesting to have smaller technical blog sites that can be moderated, and the most popular articles get fed through to tss for potential publishing
anyone know of a plugin similar to firebug for ie?
(off topic i know)
if it is a module it will land on classpath:
well, if it’s war host pacakge, webapp makes little sense ;9
g[r]eek: yeah, could be
but that kinda defeats the purpose of writing with a specific community (locality) in mind
interesting idea though. i’ll give it some more thought
src/main/resources right? i put it there but it still complains; anything else i need to do
is it necessary that I create ApiUncheckedException ?
an example that comes to mind – i’d be very interesting in reading articles from indian companies that provide outsourced development services
if it is there and you have a build that is correct it should be fine.
gawd excuse my english
ernimril, but I’m using String class alot
g[r]eek: That is how they would begin.
good point
you can use String, but you should not rely on toString() to return what you want
I see. but getWellFormedString() will return a String no?
since I do not know what you are trying to do it is kind of hard to tell y ou…
yes
how come i can’t cast an object i created with Object object = new Object[]{new Object[]{something}} like Object[][] test = (Object[][]) object; ?
reflection is in most cases the wrong answer
=(
how can I read from URL and avoid java.security.PrivilegedActionException
g[r]eek: no worries
thanks that worked; resources didn’t
sign your applet…
g[r]eek: what you’re talking about can be done, but it’d be very difficult
not technically, mind you
ernimril, it’s not an applet
ernimril, http://java.sun.com/docs/books/tutorial/networking/urls/readingWriting.html
ok.. webstart run in a similar sandbox, so sign your app then… or are you using some other sandboxed environment?
I’m writing this
Good morning.
ernimril, I’m using a proxy server… maybe that is the problem
if tss somehow spawned regional sub-sites, each with their own editor in chief for supervisory purposes, and each allowing the moderation of locally produced articles, with the best being fed through to tss global. something along those lines
you have not really said what you try to do or how, provide a test case…
doAsPrivileged
what about log4j properties etc; same place?
Yup
at least that way we wouldn’t have to worry about guys like Gao
fmarceau, oh, let me read about that
g[r]eek: haha
AccessController.doAsPrivileged(subject, action, null);
g[r]eek: I don’t like your idea, I’d be irrelevant and my goal is to BE KING OF ALL OF THE EARF
you obtain the subject via the LoginContext (JAAS)
editors can be female
ernimril, in to many toString functions of my classes i’m returning MyMethods.outString(this.getClass(), this);
s/to/so
of course they’d be moderated into position too
fmarceau, login?
jottinger’s techno-harem
I do not care what your toString-methods return, I know what I expect of toString…
ernimril, i’ll take your approach as the first solution to the problem.. [interface]
because they are different types
but I’m not logging in anywhere ^^;
note that if you could describe your problem on a high level, then maybe you could get better directions…
then, one day, when anyone needs a technical article, they can search global tss for things like “java 1.5 jboss 4.0.5 thisThatException” and some bloke in panama will have written up a solution
joedj, is there a way to nest arrays and then cast back?
as it is now you say like “my toString-method does not work”
wait this is beginning to sound like google.
g[r]eek: heh
http://java.sun.com/docs/books/tutorial/networking/urls/readingURL.html
only the URL is different
ernimril, I have a class with so many fields (and it extends another class with 5 fields too).. and i needed to output the fields in toString if they’re not null.. using if/else so many times kind of suck so i decided to use reflection..
does that example work for you (when it is as on the website, no edits)
fmarceau, I’m not sure if jaas is what I want since I’m not really trying to log in anywhere
only if you create it like new Object[][]{new Object[]{null}}
ernimril, collecting the non null fields in a buffer and printing them..
bbl
joedj, if you have to specify the [][] then how can it be done dynamically?
ernimril, this is mainly why i had to use reflection in toString
ok, that does not need to throw any exception….
joedj, is there a way to use reflection?
you don’t have the choice since you’re not gonna change the policy file on each machine the applet will run on
it is not what I would do, if a field is null, then I want to know that
InvocationTargetException, IllegalAccessException
hmm.
ernimril, you could know that.. but there are so many fields
1) do not use reflection 2) catch the exceptions internally and handle it
if you have many fields then chances are that your class tries to do too much
fmarceau, I don’t have an applet
ernimril, i’m setting the non null or empty fields to NOTSET
use reflection to do what, exactly?
instead of “null”…
err
i’m setting the null or empty fields to NOTSET
i meant to say that.
joedj, a function based on a counter that can nest arrays and return something that can be cast to the n demensional array that was created, i don’t see how though if one has to specify the [][]..
ok, it looks like you need to tell java to use your web proxy then
euh sorry… i though i’ve read that
NOTSET instead of null, NOTSET instead of empty.
Which one of the java datastructures is a sorted list. I for instance want a sorted list of Integers. Then I want to do: instanceName.getFirst()
ernimril, and as I said earlier, I get [for both urls] the page, but before that I get a huge pile of exception info
ernimril, how do I do that?
It should also have a map type structure, with key=value pairs, and sorted by value.
ernimril, methods 2) seems what I need.. but in that case ignoring a new interface.. and not covering all the exception in ApiException.
method*
Oh, heck, who knows… Something like this?
you google, I do not use a proxy so I am not sure… (I think you do something like “java -Dhttp.proxy=…. ” or similar)
~tell fifo_ about javadoc SortedMap
fifo_, please see java.util.SortedMap: http://java.sun.com/javase/6/docs/api/java/util/SortedMap.html
isn’t there a list of java datastructures in the docs?
I can’t find such a page
ernimril, isn’t there a way to tell an application to use a proxy from within the code?
why do you care about dynamic when you want to use a cast like (Object[][][]) anyway?
I would probably still question your use of toString(), it is not a method that you should use to format data for the end user
you can probably use System.setProperty to do that…
but you still need to google for the correct property
joedj, because you just said when i create it i can’t just use an array of an array of array, etc.. i have to do array[][]{array[]{}} etc… how do i do that without knowing how many demensions it starts with?
ernimril, but my toString calls outString(this.getClass(), this), and inside that I use StringBuffer to form the output.
thanks, ernimril, now I know a bit more what I should be looking for
again, why do you need to use toString?
how do you do the cast without knowing how many dimensions it starts with?
joedj, the person outside the function would do the cast on the returned object
ernimril, because mainly i’m dealing with Strings.. and it’s a function of Object.. overwriting it is nice..
heh, assenta is really cool but is absolutely slaughtering MS outlook performance… and outlook wasn’t that great of a performer in the first place
why do you need to use Object? why not use SomeInterface with a well defined method that returns a string?
too much work!
ernimril, so back to your solution # 2
I still have very few clues about what you are trying to do, but I guess that it is what I would do
you can do it with Array.newInstance
e.g. (int[][])Array.newInstance(int.class, new int[]{10, 20}) creates a 10×20 2-dimensional array
joedj, ah ok, thanks that helps a lot
man i love maven; it’s so much less work compared to ant
mvn rocks for sure
mmm mant.
er
mmm, ant.
ernimril, fmarceau, I tried both the -DproxySet=true… and System.getProperty().put(“proxySet”, true);… but I still get the exact same exceptions
Is there an easy way do a lookup on a collection using it’s hashcode?
huh?
ernimril, ok well now getWellFormedString() calls my static function that performs the reflection stuff and i’m able to throw ApiCatchedException in it. nice.
I have an object X, which has a field Y. I want to be able to lookup X in a collection using either X or Y, because X returns as hashcode Y.hashCode().
no, fifo_
dmlloyd :/
So I would just have to create an instance of X everytime?
seems like you need to set proxySet, proxyHost and proxyPort, did you set all 3=
s/3=/3?/
How heavy is instance creation?
ah, I think I know what’s the problem
it depends
ernimril, yes of course, that what the “…” was there for
fifo_, quite cheap if the objects are small and don’t live long
ok, I am out of options, google more and see if you can find anyone else that has that problem…
(since it works well for me)…
I have a set of objects (each associated with a connection). The object only contains a channel and an Integer field (used for sorting by activity). I want to be able to do a lookup on a SortedSetThisObject, using the channel. I figure by your statement this would be cheap/fast?
These lookups happen often
maybe you want a Map
dmlloyd, it has to be sorted
the use a SortedMap
I basically want to retrieve the least active channel
dmlloyd, thats what I am using
dmlloyd, oh
a LinkedHashMap works for doing LRU type things
works well
dmlloyd, but SortedMap sorts by Key.
dmlloyd, LRU?
least-recently-used
LRU…oooo
ernimril, is there a way to “disable” exception messages?
I wonder if that would work
catch the exception and ignore it..
ernimril, can’t do that
(but if you ignore it then put a good comment in the code)
most sorted maps can take a comparator to sort by
PrivilegedActionEdception can’t be caught from the body
or something
I tried that earier
so you can sort by the value
How do I make ant tell me what my current working directory is? I just want to echo it right now.
“java.security.PrivilegedAction is never thrown in the body of corresponding try statement”
ernimril, so I don’t knwo what to do
i have downloaded as2ant_2.2.zip and apache-ant-1.7.0-bin.zip from sourceforge I am trying to build as2ant which has inbuilt swfmill mtasc and things like that. but when i run ant from it bin as ant build in as2ant dir i get swfmill error . i think i need some advice on build.xml . i am on
command line without access to eclipse. and i cant sudo apt-get
ernimril, but the comparator supplies the key. So unless you have a field in the key, which contains a reference to the value – you can’t. or am I missing something
you are correct
i have changed build.xml to build flowplayer.swf
can anyone have any pointers
I guess that the main reais is for when the key does not implement Comparable
s/reais/reson/
Anyone know how to get ant to echo a pathelement? I just want it to spit out the string for the directory
is this correct? public class NITFItem extends Item implements WellFormedString
anyone
b0r3d, yea
damn not
Assuming that Item and WellFormedString exist/are imported… yeah.
So I have the SortedMap. Htf do I query it to get the 2nd/3rd from the top?
but WellFormedString has getWellFormedSting(), and in NITFItem I’m not implementating it, eclipse doesn’t complain!
implementing*
does Item implement it?
hell yeah
then thats why 
err not.
hmm. NITFItem extends Item too.
and then your “implements WellformedString” is superflous
Use javac. Nuke eclipse from orbit. That’s the only way to be sure.
hehe
meh.. silly people..
This isn’t working.
I think I have to put implements WellformedString explicitly for the subclasses
b0r3d, what do you mean?… if its superclass implements it it is not needed..
subclasses always implement whatever the base class implement
but I need a local implementation of the subclasses
then just override the method?
oh no, everything is screwed.
lol
ehm, …
And the SortedMap/Set doens’t update itself, nor provide an update method.
why is it screwed?
It relies on the structure it builds when the object is added to the list
if you mutate the key objects in a map you are in big trouble
ernimril, yeah – not if the hashCode stays the same
but the SortedMap doens’t even use the hashcode for some reason
at least – in a HashMap i mean
no, it uses compareTo only…
System.out.println(_n2.getWellFormedString()); doesn’t return anything anymore
no exception no nothing
ernimril, which one does? the SortedMap?
b0r3d, and what class is _n2? and from wich inheritance does it get its implemenetation of getWellFormedString?
TreeMap (the easiest way to get a SortedMap)
hi .. this is very basic question but i dont understand why is Interger i = new Integer(10) same as Integer i = 10;
loesh, NITFItem extends Item which extends Entity. I have implements WellFormedString for each of them.
it is not the same
i think he’s asking why they’re not the same
they both contain 10
“Integer i = 10″ is sytactic sugar for “Integer i = Integer.valueOf (10)”
b0r3d, ok, but which class actually implements the methoid?
they both contain 10, one uses the shared Integer instance, one is a new created
so they ought to be equals but not ==
loesh, all.
thanks
it’s nice just to sit here and read what people like ernimril writes.. and learn a little java
b0r3d, ok, then if _n2 is a NITFItem the method getWellFormedString() in NIFTItem should be called when doing _n2.getWellFormedString()
so how does that implementation look?
loesh, public String getWellFormedString() throws ApiCheckedException { return MyMethods.outString(this.getClass(), this); }
Can anyone tell me how to make ant echo a path? I have a path with a pathelement set to . and I’d like to echo it so that I can see the path on the screen….
try echo
I need to convert HTML file to text file
yeah, did that
html is text…
it just prints out ${path.element}
I Want it to print /home/user/path
b0r3d, ok, and then what does MyMethods.outString(…) do?
you can try this, but it only works for well formed pages: String plainText = page.replaceAll (“.*?”, “”);
I tried that, it doesn’t print out the actual path, it just prints out the name of the variabble
ernimril, html has all sorts of tags
loesh, http://rafb.net/p/t6nj6o52.html,
or use a html-parser to get all text-nodes
does echo not support variables?
i would be willing to bet that programmers are the backbone of most companies in the world today
can you only echo string literals? that sounds useless.
?
ernimril, plus there are many characters in the HTML like “ü”
[echo] ${some.path}
again
they are harder tro translage
loesh, i uses reflection to get all the values of the class and append the value if set otherwise NOTSET.
hearing this I just love make more
or in this case it returned : [echo] ${path.element}
are you sure the property is set?
no kidding
I use make for all my projects
loesh, it’s going into an infinite loop and get killed by JVM or something..
b0r3d, yea i see..
loesh, why?
thtas probably because it calls getWellFormedString
yeah, I declare a path with the id=”some.path” and inside i create a pathelement and set it to .
do you get a stackoverflow?
lol
no nothing
the program just terminates
after you check that its not the getClass method, also check that it is not getWellFormedString ….
loesh, I can make it not call getWellFormedString
yeah that’s it.. let’s see.
because that would give you an infinite recursion
thanks man you’re the best
it works?
property name=”output” refid=”path.ref”/echo message=”${output}”/
loesh, yes it does
nice
ah! so it has to be a property? echo won’t work for pathelements?
so it seems
so do I wrap my pathelement in a property?
http://ant.apache.org/manual/CoreTasks/property.html
i have downloaded as2ant_2.2.zip and apache-ant-1.7.0-bin.zip from sourceforge I am trying to build as2ant which has inbuilt swfmill mtasc and things like that. but when i run ant from it bin as ant build in as2ant dir i get swfmill error . i think i need some advice on build.xml . i am on
command line without access to eclipse. and i cant sudo apt-get
loesh, i thought something went wrong with eclipse for instant.. heh
b0r3d, well if you are uncertain, allways try running stuff from the commandline
the property type doesn’t support a nested path element…
eclipse is very nice but well it might mess things up..
what do you mean? it says so right in the docs
why do you need it to work that way?
haha
what’s wrong with declaring the path, and then referencing it by ID
I just want to echo the directory. That’s all. I don’t care how it happens.
I need to use the directory to make a decision later also.
so it’d be nice if I could branch based on which directory I’m runing from.
path id=”duh”pathelement location=”.”//pathproperty name=”dir” refid=”duh”/echo message=”${dir}”/
though for the record I think that’s just going to print “.”
Thannks… don’t understand why you have to use a refid, but that works great!
no wait… I DO understand why I have to use a refid… learn something new every day….
Is it essential to declare enum as public ? I am trying to access enum Type from my class but enum has default accessor type
What is the best way for me to read a file using ANT?
hello, i want to learn java programing and development.. I do not have a programming background at all though I am very good at web design and web development. I heard that java is the way to go if I want to learn programming and I have already started with the tutorials on the Java website
and I was just wondering my being new to programming is there a better guide or another source i should seek out to learn java or should i stick to the w
$diety I hate this policy of not beeing allowed to delete files from projects after first commit to the release tree
Nope.
You’re doing the right thing.
You may want to find a book that covers object-oriented programming in a language-neutral way. To understand the concepts.
crap… Been thinking about this… Since getting a resource from the classloader means you can’t use a File object, is there a way to ask the classloader (or Tomcat in general) for the directory path of the deployment root, so I can build a File object?
ok cool, someone had told me i shold get “java for kids” or “java for dummies” books but the website seems to cover things quite well
Nah.
I’ve got a config file in WEB-INF that I want to periodically check the file modification time to see if I have to reparse it
As a non-programmer, you should be more concerned with OOP basics than Java calistenics.
[TechGuy]: or you do some ugly hack to inspect the url you have…
any ideas on where i can learn that stuff? Books? website?
This is in a background processor thread spawned from an init servlet. It’s not called from a URL
Books.
Some websites may cover it well. Google for object-oriented programming concepts or similar things.
[TechGuy]: getResuorce gives you an URL, it was that url I meant that you can inspect, if it is a file:///foo/bar/webapp/… it is quite easy to get a file (, but ugly)
indeed
nivekc1, maybe not the right level, but there’s a series of books called “How to think like a computer scientist”
nivekc1, and there’s one for Java too
Was just trying to think of different ways to get to a file modification time
oh also I am a Windows free user (I hate windows) is it going to be ok going ahead with this in Linux?
nivekc1, the best part of that book is that it’s entirely free, in PDF format
thanks ill try that out
Sure.

I won’t any more
You ruined it you meanie! *throws fit*
ie blows….
cool thanks! and just to clarify on my last question there this is ok to go ahead with being that I am a Linux user and will not even consider Windows
sure
java works fine on linux
nivekc1, I think youre safe [Mac user]
public class Err{ public String name; Err(){} public void getName(){return name;} private int hour; } Why will this class not compile.. I am doing practice test and I do not have java installed. Thanks
Install Java
http://www.innovation.ch/java/java_compile.htm
great you guys have been very helpful, I’m sure I’ll be back later after I begin reading and i’m stuck in a “huh?!” part lol.. thank you.
thanks thats gr8 erni
nivekc1, it also helps if you have a “problem” to solve
nivekc1, if you just read the books… I find it hard to learn, I have to have something real to solve
what do you mean?
How do you add an external resource to a jar through ant? such as a configuration file?
grumblefuck
Monday mornings.
nivekc1, like “OK, I need to get the files from a server; how do I do that? to save on my computer”
oh i see
I was told to begin a project, and as i learn new tings update my project as i go and then once i am finished i should have a working program
sound right?
nivekc1, exactly
that and get a nice IDE to start
such as eclipse
O_O dont start with using an ide
~newbie ide
newbies shouldn’t use IDEs. http://weblogs.java.net/blog/editors/archives/2007/02/you_better_get.html and http://weblogs.java.net/blog/gsporar/archive/2007/02/tools_that_do_t.html
what the bot said …
you can also make small projects, and write class files for those small projects and then make the final project that uses the class files from the smaller test/projects
what they should use Emacs, VI?
totic, well yea, or something simpler…
no..
any editor is fine
with the two Integer objects? or perhaps an Integer and an int?
totic, any text editor
Just the jump to learn Vi or emacs should scare them enough
then go for a simpler one
or well both emacs an vi are extremely easy to use at a basic level
open emacs and start typing your code
and he said he vas a linux user, my bet is that he should be familiar with at least some decent text editor…
loesh, but I find it always going crazy [since I press control key in wrong places and times]
daredemo, hehe yea but eventually you learn to do it right…
~tell gaillard_ about autoboxing
gaillard_, autoboxing is http://java.sun.com/j2se/1.5.0/docs/guide/language/autoboxing.html
[krustofski], thanks
loesh, like opening a new buffer in the same window and you can’t see the original anymore and you get a heart attack since you last saved in the morning
haha i see that any text editor will do right? ill just keep to my basic text editor in ubuntu i use it for html coding should be good enough?
daredemo, oh well emacs might not be the best choice if you are not willing to take some time and learn it…
for learning, that should be sufficient
nivekc1, the added value of some text editors is that they close “(” and “{” and so on
oh i see
loesh, I finally learned it this summer
yea and well it is a nice benefit to have one with syntac highlighting, makes it easier…
daredemo, yea i picked it up not that long ago either…
such as python?
now i use it for all my coding..
loesh, had tried it many times before, but got seriously lost, but since the new version has a Mac native version, it was much less scary
well i basically took the time to go trough the tutorial
nivekc1, python?
and i try and look things up as i stumble upon them..
loesh, my first trouble was that I didn’t understand the tutorial
it is a programming text editor that is made for linux and can be found in the default repositories
hehe..
python is a language?
loesh, it was talking about modifier keys and whatnot, and I “didn’t have such key” feeling
yea it is a bit strange until you get used to it..
nivekc1, python is a very good programming language [because I use 3D app called Blender and all scripting has to be done in python in there]
How do you add an external resource to a jar through ant? such as a configuration file?
update the jar
but at build time?
im not talking about the language there is a text editor call python too made for programmers it does what you said closes ( and { and what not after you select the language your using
add that resource to fileset
thanks everyone for your help, i have to go to work.. bye
a stupid question, does java have a way to run .java without compiling .class?
erm… no
you can certainly compile on use, if you need, but… ick
jottinger, well, is there a compiler for mobiles? :p
in an interface what attributes are allowed ?
public / private?
none
everything is public
like this? fileset dir=”${classes};${basedir}/default.xml” /
though … maybe protected is supported.
~tell totic about tias
totic, Try it and see. You learn much more by experimentation than by asking without having even tried.
is default.xml a file?
I already did and it didnt work
yes
does not work
well there you go
heh
public String name; did not work either..
it accepts method definitions
only?
I thought that would be an easier way for you to say no, it has to be like “blah”
I sometimes find myself in a bus… and can’t take out my laptop… so, I wonder if there would be any way to use java on a mobile [nokia], use in the sense of writing code and testing
String name = “I can never be changed because i’m a ‘constant’”;
yes?
target name=”build” depends=”compile” description=”package the .class files as a .jar file”
jar destfile=”${basedir}/jars/${ant.project.name}.jar” update=”true”
fileset dir=”${classes};${basedir}/default.xml” /
/target
crap
sorry..
String name;
http://rafb.net/p/3lwMBx97.html
that whave I have now
it works without the xml file
I am using gaim
because an xml file isn’t a dir.
right…
and fileset

how would i cache jdbc access transparently if there are no pojo domain objects; can’t use ehcache because there are no pojos as such and not using hibernate; any ideas
~coffee cheeser
yum
use hibernate.
i can’t; this legacy db schema is horrific to say the least; and we don’t have the time to model it; it’s quite big
Heh
how are you accessing the tables? (I mean, are you using a DAO?)
uh, you want to cache it without modeling it? somehow, that doesn’t make sense.
Hm. I’m tentatively impressed with IDEA
yeah there wasn’t a data layer in the previous implementation by someone else; but i am rewriting it so now it has dao interface and jdbc implementations
why?
then memoize based on the primary key. And, BTW, I’m so sorry.
haha
Just the UI so far.
Could you elaborate a bit I don’t understand what you proposed.
in the dao… have a map of primary key/object
First impressions of it seem more usable than those I’ve seen previously. I’m very prepared to change my mind though.
and never ever let anyone access the DB except through that map
and never use more than one process to access the DB
if you violate those restrictions, you might as well… use hibernate, because you’ll be rewriting it at that point
haha
thats what ive done
Narada im in your boat
and you’ll pardon me, I’m sure, but I think Gavin did a better job than either of you will
well i havnt rewritten hibernate (its way more advanced) but i have a nice OR mapping framework that allows me to write nice litte apps pretty quick
Couldn’t he use ibatis and map the old cruft?
they said they couldn’t model, or some crap like that… plus, ibatis won’t cache
jottinger sometimes its easier to ryo framework than fight with the server guys to get some new thing installed like hibernate
to clarify by primary key to objects you mean an arbitrary key to access that result set and the result set?
two strikes then….
I’m familiar with it
im sure you are
there are no domain objects in this case; just maps and strings
If I have a path like ‘/path/to/file’ how can I tell java to give me back just ‘file’?
It’s a string..

cool
although it relies on the ability to determine how long an array is!
so be careful!
Yeah, I have to get into some halfway-tolerable recent music. Soundtracks have burned me out
jottinger, unless the string is null, would there be problems? I mean, rellis is splitting a string to get an array

anyone know of any good references for history tracking within a database?

How long does it typically take a JSR to get adopted into the core language API after a final approval?
MarkT-: 8 months at BEST
ooo, core language is even longer
look at generics
i think it was the last to go in
yeah, closures will take even longer
closures will be in java 7, won’t they?
maybe
language changes are ssslllooowwwww
not necessarily
java justifiably resists language changes… 1.5 was a surprise with that
blah
I was talking about a JSR that’s just an API, not a language change.
jottinger not really sure what you mean. essentially i need to track for example an account record and its various “states” so whenever it gets updated i have all previous versions
MarkT-: which one?
the system i have right now is alright, but wonder if there might be a better way that i just cant find
why not use explicit versioning?
hibernate et al support that out of the box
actually an aop interceptor that caches on method signature should work
because i cant use hibernate =\
JPA?
atleast at this time
a lot of jsr’s are just API’s.
MarkT-: I’m familiar with the JCP, dude.
Or were you asking which jsr _I_ was referring to specifically?
yes.
yes. duh.
8^)=
sorry… (slow)
no worries.
JSR 231
haha
that one will be a LOOOONG time if ever
progress has been rapid on it, though… but as a core API? Probably never.
Why do you think, jott?
OpenGL isn’t something the platform can rely on.
~jsr 231
aditsu, jsr 231 is http://www.jcp.org/en/jsr/detail?id=231
opengl is fairly ubiquitous… I can’t think of a single graphical platform that isn’t obsolete and doesn’t have it.
groan. Ya know, screw this tracking of file modification time
heh
i’m not sure why there needs to be a JSR for that.
MarkT-: not knowing what you said, you said it.
I’ll just reparse the config file at every iteration (30 seconds). It’s not that bad
so many of those JSRs are more product requests than actual infrastructure issues
would having opengl bindings actually help java?
i seriously doubt we will see a game in opengl anytime soon, and what other industry would use it?
er not opengl games but java games
anyone have a guess at the most popular java gaming platform?
JEE?
hahaha! No!
JME!!!!
cell phones?
dingdingding
ah.
MarkT-: ever see a cell phone with opengl?
opengl
Puzzle Pirates
ever see a cell phone with directx that you could afford?
me neither!
directx is a windows-only thing.
puzzle pirates
Oh wait, you haven’t answered yet
MarkT-: note that there are handhelds that run windows….
my desktop can intercept radio waves.. does that count?
okay…but it’s a noteworthy title written in Java
sure it is
opengl is cross-platform. directx isn’t.
dosnt matter
Doesn’t matter why?
the gaming industry relies on the windows platform
/ignore Aradorn
not all of it.
that’s the _current_ state of things, yes.
the big studios do
Like Blizzard?
like id?
Oh, except they have a Mac build of their games.
You lose again.
well, I don’t really want to drift from the topic being about java here… so I’ll refrain from arguing.
build platform != runtime platform
anyhow.
What’s up all?
MarkT-: in any event, opengl isn’t likely to become part of the java distribution.
the jre is too bloated as it is, anyway
the jogl bindings are pretty easy to use.
Not opengl itself… just the api.
no need to make it worser.
that has 0 to do with it.
they are adding a whole bunch of stuff in java7. Some of it’s pretty cool.
