There are far worse ways that Java could go than becoming more lisp like.
Nah. It’s not perfect, but we don’t need yet another lisp dialect
;
How does java decide whether to use RasterPrinterJob or PSPrinterJob when printing?
I’m not saying there aren’t better ways it could go as well.
is there a truly cross platform 3D library I can use for java? JOGL requires compiling for all sorts of architectures, and Java3D appears to be the same way, unless I’m misunderstanding something
um….how isn’t jogl cross platform?
you need native libs, unless you want software rendering 
OpenGL is a portable library.
Rather, implementations seem to exist in several OSs
but don’t I have to include binaries for a whole bunch of architectures?
yea but thats the same way for anything
yeah, you do
you have to do same thing with JDBC, iirc
Can’t make a magical jar file to add to my build path?
You’ve gotta provide the dll/so that supplies the JNI boilerplate code.
you can make a loader that will provide interface to the libraries you need though.. and that will decide, based on environment, which libraries to use
yeah
so the rest of the code will be oblivious to which library you’re using, as long api is same.
And implementations of OpenGL are pretty consistant across the board…
I was hoping to avoid something like that, because right now my program is neatly packaged into one jar host file
So?
google stuff up.. maybe someone did already that for opengl
ok
I think the classloader can somehow load the native lib, iirc.
er, no Runtime.
What is the app?
It’s for working with Chemistry. There’s a portion of it where I’d like to feature some 3D graphing (very simple point plotting, line drawing)
opengl might be overkill then.. i think someone mentioned along the lines of java3D in the past
~java3d
dfr, java3d is an api to add an extra dimension to your application, see https://java3d.dev.java.net Also see JOGL for hardcore openGL coders.
OpenGL is fun!
oh, i bet.. i never played with in in OO though
OO?
Object Oriented?
ya
the best i did is using it from C++ a few years back.. and i think it was quite and quite C
eh…? It’s not really object oriented.
I’d imagine that the java wrappers provide some OO-ness though
It’s a bunch of functions, but it has some elements of object oriented ness.
no, it doens’t.
duh.
It’s pretty much a big class called GL that’s got a shit load of static methods.
duh
that blows.
not really.
frankly, I’m not 100% sure about openGL structure, so it might be okay.
It’s sort of stack oriented…
but i kinda prefer to avoid mixing OO with procedural style
meh
OO is overrated….
and underdefined
I’m not saying that OO is the shit, I just advocate not mixing the styles too much.
unless you _really_ know what you’re doing.
of course, that’d imply that no one else knows what you’re doing
so… if anybody here is in the Triangle (RTP, NC) area, feel free to join us over in #trijug (Triangle Java User’s Group). 
anyone know if there is an official standard behind locale strings such as en_US, fr, … ?
i know these strings consist of ISO 639 language codes and ISO 3166 country codes, but i mean a definition for the whole string
goodnight fellas
peace-keeper: Unicode.org?
peace-keeper: at least the ones used by Java are defined somewhere in the javadocs

There’s not degrees of officiality…
is it a know problem with sending a bunch of booleans in serializable’d class over sockets?
What’s the problem?
well, it seems the data is not what i sent
i’m sending like a event structure
of my movements in a game
i have this event structure and processes it localy (it works fine) and then i send this event structure over sockets to my ‘enemies’
Booleans? Movement? Like “Left? No. Right? No” etc?
yeah
and somethimes it reacts very strangly, for instance my up and down could make the player go left
it seems that the booleans gets scrambled or something along the way
it seems like the other datatypes works fine, for instance i have a byte with a id
maybe you could log the bools that go on one end and that come on the other end and diff them
to make sure the problem is with serialization.
ive logged them to the extent that i print out what i get, and it differs
keyhandler.process(player, playerState);
Networker.getInstance().sendPlayerState(playerState);
what happens when they get the playerState object is that they run the keyhandler.process on the object
but as i said, the data is different when it arrives.
worth mentioning is that i’m testing this on my loopback interface, so there shouldn’t be any problem with external things
and I add “Foo”, stringArray to it…if I later change something in stringArray…does it change in the HashMap? I guess my question if it is passed by value or reference
eckser, yes
Okay, so it will change?
everything is passed by value, but not the value by which you are thinking
gotcvha
and yes, it will change
objects are effectively references.
gotcha* thanks
which are passed by value.
I have one more question…is there anyway to only put the keys in and not the values of those keys (array of strings)?
null is a valid value.
read the javadoc for HashMap
Thank you
however, be careful with it.. since if a key doesn’t exist map.get will return also null.. meaning it will give same return whether there’s no key or there’s a key with value “null”
God damnit

how do i deal with “unchecked cast ” warnings?
I have like 200+ warnings in my project.
You cast
ya check the cast…
SortedMapObject,Object[] sm=(SortedMapObject,Object[]) appdb.selectGvmWithNumber(getLoggedUser(),currentRowActionParam).getRows();
what type does getRows return?
result in “unchecked cast from object to SortedMap”
If you know that they are useless:
@SuppressWarnings(“unchecked”)
regarding that he doesn’t know what causes them, supressing them is a bad idea.
Uhm.. His casts may be completely valid. IF(!) he doesn’t know what they mean I agree.
the .getRows() method returns a SortedMap[] ; while I need SortedMapk,v[] . how can i fix this?
sleepster++
doesn’t matter. use unchecked cast
you return SortedMapk, v[]
you can not fix it… you can supress the warning though…
yes

Email.
I don’t use your email service.
Someone knows ricky AT myserver.com and knows that you’re ricky_clarkson.
The messages had your /nick in the subject line.
The only thing I use it for is to forward mails from my work account to gmail – I’ve never given the address to anyone.
They came from a number of spam zombots, mostly in the US.
Check at work then.
Someone may be infected.
If you can disable incoming mails to that account, that should fix it.
Is there a way to flush/reload an audiostream so that I can play it more than once?
I only run a cronjob to do the forwarding, once per hour.
I didn’t want to disable anything without checking with you first.
And that’s on lavender anyway (or whatever it’s called now).

Anybody know of any libraries to export SVG files?
~batic
ernimril, I have no idea what batic is.
~batik
ernimril, batik is a set of Apache libraries for manipulating SVG documents.
Cool.
^^^ that is what we use at work…
I have not worked with it, but I think you get a Graphics2D that you can “draw” on…
I was thinking it’d be cool to expot the results of JSizer to an SVG.
ernimril, wow, really? you draw to a graphics2d and it magically becomes an svg?
that’s pretty slick
more or less, that is also how iText work for pdf-images
(using batik)
I have only looked at the code once, a long time ago…
just fop
itext is really much nicer…
it is also faster and uses way less resources…
if you are drawing a geographical map then itext is definately more fun, just get a PDFGraphics and paint your component
yeah, I wouldn’t use fop for drawing graphics… different problem domain
Why am I such an SWT whore?
because you suck, obviously
NO U!
do you create any large documents with fop?
ernimril, I haven’t tried anything longer than maybe 10 pages
generating telecom invoices from xml invoice data
ok, we do, or rather we tried, got OOME (I told them so from the beginning, but they still tried to use fop… damn sometimes I hate being right…)
that and generating my resume
ernimril, and yes, you’re right, I wouldn’t want to generate huge (as in hundreds-thousands of pages) documents using fop
for smallish documents, it makes sense
I wouldn’t publish a book with it, I think…

Is using an xml based configuration file perticularly a bad thing?
no
xml-based config file is trash unless you have some sort of well-defined schema
and you have a good reason for it
otherwise, why not .properties, etc.?
Ther reason being it needs to have scope like structure.
Properties classes can also read a xml prop file
its really basic tho
It needs to be read in C++ and Java. And parsers for XML are easily available in both languages…
almost all java frameworks use xml as conf files
atleast the one ive worked with
just make a clear schema or dtd so you can validate easily
is there any way to get a jax-ws enum method parameter to not have minOccurs=”0″ in the generated WSDL/xsd?
no
generate the wsdl yourself
doh
because java itself does not have a “NotNull” declaration
I don’t see why the @webparam not have an option for it
saying if its required or not
yeah, a well defined schema helps…
So that the parsers in both languages actually can enforce some set of rules.
any swing gurus around?
ask your question and find out
I have one textfield per tabbed pane and when I switch tabs, i want to put focus on the textfield. I do this by using a change listener. stateChanged() calls a method which tries to set focus. This fails.
So, I tried having the method statechanged() calls create a new thread that sets focus and i put this thread n the gui thread with SwingUtilties.invokeLater(). It still fails.
darn that was going to be my suggestion
I’m not sure I can’t get focus on the text field… is anyting obviously wrong in what i descriobed?
why are you using a thread?
because gui drawing takes place ina swing thread so i set focus in another thread, using swingutilities should guarantee it happens at least after the tab is displayed
first of all
you need no threads
ok. can you tell me what’s wrong with my design?
stateChanged() { EventQueue.invokeLater(new Runnable() { pv run() { field.getFocus() } });
second of all,you need to describe wtf is “it still fails”
~tell jdroid- about doesn’t work
jdroid-, doesn’t work is useless. Tell us what it is, what you want it to do, and what it is doing. Consider putting some code and any errors on a pastebin. (use ~pastebin for suggestions)
what else would “it still fails” mean if i’m saying the text field isn’t getting focus…
;P
you could be saying you’re getting an exception
we don’t have ESP
you also aren’t describing the method by which you are requesting focus
requestFocusInWindow() sometimes returns false. when it returns true, the item doesn’t get focus
urequestFocusInWindow() sometimes returns false. when it returns true, the item doesn’t get focus/u
why event queue and not SwingUtilities?
because EventQueue is the proper place for invokeLater, SwingUtilities is simply retained for backward compatibility
the code you wrote is essentially what I had, but using swingutilities, which also IS a thread, it’s just the swing gui thread
no, it’s not a thread
ah, ok.
you are just specifying a piece of code to run
different semantics
sure it is. you’re runnable gets run in the gui thread.
you aren’t creating any thread
you are just requesting a piece of code to run
anyway, sounds like maybe you aren’t getting enough delay by using invokeLater
ok. my terminology was wrong before…
you might really want to *create* a thread sleep a short amount of time and then call invokeLater
i haven’t tried EventQueue. But the error I described happens with SwingUtilities.
there is no error
the behavior of using SwingUtilities and EventQueue is the same
hmm… So I’m confused why if the tab being clicked initiates the creation of the runnable which is invoked later, why does it not happen sufficiently late enough?
i was under the impression gui drawing happens in one thread where my runnables are run in sequence with anything swing is doing on it’s own
simple, because it’s likely there are other events that occur after your “invokeLater” which draw focus away
it’s an “event queue”
i need some pointers for obfuscating a war file with proguard, anybody able to help out?
that means items are queued for execution
sebr obfuscate first, pack war later
ok
sebr and don’t obfuscate the main entry points, servlets, filters, etc.
well i’m not upto that yet
don’t really know how to create the ant task
sebr then you can’t obfuscate
sure
ok. if I have a window listener and window focus listener and that’s it for listeners, do you think they are interfering?
jdroid-, has nothing to do with the listeners
hmm… do you have a suggstion for how i can look for other events that might interfere then? or maybe something i could read that’d help explain the stuff going on here?
jdroid-, if you don’t understand what’s going on, it’s best to see if you can hook into the event queue and see what events are being passed
oh, hmm… i’m not sure how to do that
jar basedir=”$build.home” jarfile=”${dist.home}/${app.name}.war”/
should be some info in documentation in EventQueue
should i create a new target obfuscate between compile and dist?
k. thanks.
obfuscating the necessary classes then call dist?

anyway have an opinion on spring mvc vs gwt?
they address different problems
spring mvc does not address ajax, gwt does
end of discussion
I was told that mvc could have the ajax http callback placed in the mvc?
but this seems like a “workaround” rather than core functionality
like I said, different approaches
so gwt is pretty unique?
I would guess so
Im verrrry impressed with it… but you ahve to keep your options open

sure, as Json, XML or something like it.
When you’re starting with a clean slate like I am, its hard to choose an EE framework/platform… spring vs seam vs struts vs portlets vs jsf… *sigh*.
ahughes, it’s not hard at all
you just and choose the best pieces
spring for the backend along with java ee5
wicket++
then you’ve got seam and wicket
I think are your top contenders
there is not necessarily a best, though =P
pick the best for your needs, obviously
if you need an ajaxy front-end use gwt or whatever makes ajax work out easily
You can always integrate Gwt with Wicket if you want.
why not portlets?
Or just use the built-in.
Why?
because portlets aren’t a framework
portlets = servlets
THey are handicapped WebApps
except they’re made to be rendered on the same page with other portlets
And a cludge to get to intercommunicate…..
what’s so kludgy, use an external mechanism, jms, etc.
right.
jmx normally
I’ve done it with DWR, I’m talking of updating one from the other.
jmx is “wrong” from a semantic perspective
Which is being addressed in JSR268
we’ll Im no closer to deciding… I think its really Portlets as a container or Seam + gwt for the AJAX/JS.
seam seems to get a lot of publicity
coversations are cool

it sounds like you know what you want to do, just not how to do it… rfc will help with http
fredy22, http protocol, network, socket, server, client
fredy22, sounds like you have the keywords already
you could probably do away with “network” and “socket” and still come up with reasonable results
thanks
jdroid-: I have already read the rfc
then what aspect do you not know?
just what i was gonna type…
what exactly are you looking for
If I use seam, how can I add something like a CMS to our site, and a Wiki? becasue this is the advantage of portlets… plus the security container
ahughes, how is that an advantage of portlets?
in your pages, just include the “CMS” component
as an include
my female coworker just said she’s “working for pennis”
or the wiki as an include
I have read the rfc, but I have no idea how to implement it. I haven’t dealt with java networking in the past
like a jsp include?
fredy22, then it sounds like you need to read the tutorial there
or an iframe?
~tell fredy22 about networking
fredy22, networking is http://java.sun.com/tutorial/networking
ahughes, your choice
fredy22, so using servlets, etc. is out of the question?
~tell fredy22 about javadoc HttpURLConnection
fredy22, I don’t know of any documentation for HttpURLConnection
eh?
Javadocs down for now.
well i have a object stream going between a servlet and an applet. The applet is dynamically resized with the browser window with a bit of javascript, and it also calls a method in the applet to let it move things if need be, its one big applet for the window. Someone please give me a compelling
reason not to use this as a very very interactive website?
http://java.sun.com/javase/6/docs/api/java/net/HttpURLConnection.html
javabot should say so
I guess the factoid ’sensayuma’ might be appropriate:
ain’t you got no sensayuma?
it’s an assignment for school, the specifications didn’t mention servlets
fredy22, if you’re using java6, cheat and use the built-in http server
java 1.4.2
if it’s an assignment for school, you’ll probably lose points by using the built-in http server…
http://java.sun.com/javase/6/docs/jre/api/net/httpserver/
java 1.4.2?
people still use that crap?
GET http://java.sun.com/javase/6/docs/jre/api/net/httpserver/spec/
I have seen the HttpUrlConnection class but I cannot use it from the server’s side, I can only use Socket class. That is my main problem
use that then
fredy22, well then, you have the networking tutorial
you have the http rfc
any opinions on doing what i wrote?
you’re done
gaillard_, applets suck
?
pfn, why?
fredy22, your problem is solved by combining the two
gaillard_, accessibility, ease of use, ugly gray boxes, etc.
pfn exactly..could you please provide me with some advice?
I have
It’s homework, you are supposed to do it.
I have given you the networking tutorial
and you already know about the http rfc
what more do you expect?
pfn, accessibility? ease of use is up to me to make good as well as ugly stuff right?
pfn, if i were to do it well isn’t it much more capable then anything out there?
pfn, full graphics library and such
I can’t combine socket class and httpurlconnection class. that’s the point I need advice
gaillard_, depends on what you’re doing, but flash tends to be more capable…
fredy22, httpurlconnection = client
duh
fredy22, you write the server
pfn, may i ask just what the main points are? (not dabled in flash)
smaller runtime size, faster loading, better media and animation support
my problem is that in the server programm, I can’t use the HttpURLConnection class and its convenient methods on HTTP elements…
is it possible?or not?
fredy22, the httpurlconnection class is *ONLY FOR CLIENTS*
I’ve already given you your answer
1) use the builtin java6 http server
2) use your knowledge of the http rfc + java networking tutorial to write a simple HTTP server
3) use HttpURLConnection to communicate with your simple HTTP server
use 1 or 2 and combine that with 3–assignment done
any further questions will fall upon deaf ears
thank you a lot but 1) is not possible because we work with java1.4.2
anyway thanks
pfn, you sound like a microsoft rep haha
then your answer is 2 + 3
done deal
1.4 … man when will people move on
pfn, would you mind commenting on the strength of flash over an applet?
Is it possible to hide all JDialog objects made out of a class at once?
I mean the setVisible(false)
well flash is more pervasive than the java plugin for browsers
pervasive?

use a static List to track the new objects. use a static method to hide them

is there a way to configure the default fontsize for the cross platform gui? I forget its name
swing
javabot tell myrkraverk about swing
myrkraverk, swing is a windowing toolkit for Java. Tutorials: http://java.sun.com/docs/books/tutorial/uiswing/ and http://www.swingwiki.org/ also check out ##swing
hmm, yes, I know what swing is; only, in applications I *don’t* write — can I still tune the default fontsize?
setFont().
er…you didn’t write it — the program has to provide the ability to do so.
~look and feel
cheeser, look and feel is java -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel your.fine.Program

i’m working on that now.
yeah, i know. any eta?

i don’t get it. i can see it running just fine here.
maybe i’ll push up another version and see.

indeed
what are you doing to it exactly?
trying to figure out why it works locally but not on the server.
smartass–
dumb questions– ?
what did you want to know?
so, i ended up using a ByteArrayOutputStream
i write all the primitives with a tag and a packet size and then send it across the wire
and decode it similarly on the other end, seems to work great in the tests i’ve done so far
nice
the only thing that threw me for a loop was that when i grab the incoming packets i have to queue up the data because they don’t necessarly fall on the same boundaries as the packets i’m trying to reconstruct
but once i realized that it was smooth sailing

For several weeks I had a mysterious crash on my servers and gateway at home.
I couldn’t figure out what was causing it until two Tuesdays ago.
It was the server-seeking housekeeper attack.
haha
heh
turning off the computer you accidentally left on?
More likely: Accidentally turning off the computer he intentionally left on.
So I asked her this morning to go around the server area with care, etc. Problem solved. She was a bit too diligent at cleaning the area and turning OFF the boxes that “you forgot to turn off, señor Ciurana.:
“

it’s weird. the process command just returns. nothing in the logs.
not even the debug i put in.

i noticed that it doesn’t log when i tell it to either
It logs when it matters though
gremlins are obviously causing this problem.
No, she’s 60.

Ahh.
pheh, there’s no such thing as gremlins
Indigenous looking.
orange80 might be into that
it’s ghosts
I might, but… I’m not.
I had a really hot one about 2 years ago. She couldn’t do shit around the house but was very nice to look at
..
It’s always a trade off, I guess.
Brazilian girl, around 24.
you tend to want somebody to clean good
Nice arse, small tits, pretty face.
Indeed.
The one I have does a fantastic job, is responsible, punctual, humble, and loyal.
That’s the best kind of worker
She didn’t even realized that I’d given her a raise until a week ago.
That’s all you need
She tried to return the “extra” money today then I explained to her that it was for a good job over the course of her first year, etc.
That’s _AWESOME_
honesty is the best trait.
I also gave her family a bottle of spumante and a ham for Thanksgiving, and she gets a little $$ for Christmas.
uI also gave her family a bottle of spumante and a ham for Thanksgiving, and she gets a little $$ for Christmas./u
Yeah. She has keys to my house — I gotta have trust.
The Brazilian chick was pretty nice, honest, loyal, etc. but did a lousy job.
She only cleaned well when I took the day off to hang out around the house and monitor her. Otherwise she would be done in 30 minutes.
it always sucks to fire people, but…
I rather keep good people motivated.
My intern is going back to the university next week.
We hired her half-time.
And she just bought a new MacBook Pro.
We have a “bitching jar” at the office: if you whine, you put a dollar in the jar. We’re using the money we collected in the last 40 days to buy her a Speck MacBook shell as a farewell gift.
She doesn’t know about it.
unless she’s one of the 235 people who hang out here
She sort of is, but she isn’t on-line yet.
She hasn’t fully groked IRC.
well, if university is good for one thing, it’s getting a person on to IRC
I would likely have filled that jar up
at least, so it was back in my day
Otherwise she’s pretty tech adept.
I’d had you transferred to another team.

I only complain if there’s something worth complaining about
since I’ve started working on jboss remoting, I’ve not had a one, really
Better than being fired
anybody have a tutorial on how to obfuscate a webapp which is running in Tomcat?
. . .
i know, it’s a big ask
Isn’t your code hard enough to read as it is?
obfuscation is a fool’s errand

To start my anonymous implementation of Runnable i should call run() ?
yes, considering that’s the only method Runnable declares
~tell Sashlik about threads
calling run() doesn’t start anything though
stupid bot
8^)=
you call start() on a Thread object to start a thread running.
it does. just not in a separate thread
yeah, my point is that it’s just a normal method invocation. Typically when somebody says “start” they mean kicking off another thread
mindCrime but i have an instance of Runnable, not Thread
you’d be better off doing new Thread(new Runnable(){/* your stuff here */}).start();
are you trying to run some code in another thread, or are you just packaging stuff up as a runnable?
if you want a thread spawned, pass your runnable to the Thread() constructor
Fanook ok will do that
and then call start() on the thread object
ojacobson run some code in another thread
if you don’t actually want it to run in a separate thread, then it doesn’t matter.
Then you need to create a Thread wrapping your Runnable, as has been suggested, and call “start()” on that thread.
thanks, i will wrap
repetition++
maybe i could anonimously implement thread instead of wrapping runnable?
Don’t do that.
why?
you could subclass Thread yes, but it’s not really a good practice
It ties your code to being run on a new thread, making it less flexible
Fanooks suggestion is a best practice, right?
yes.
ok, thanks
and concrete inheritance when the subclass isn’t really a specialization of the super class is just silly
single inheritance kicks asses
you can always delegate thread-functioning instead of inherit it, however
well, not always )

i fixed that admin bit noted that it is not possible to edit admins currently

fwiw python spells that s = “some string”, s.join (someIterable)
hm, that would be nice.
What would that do?
{“a”, “b”, “c”} joined using “,” is “a,b,c”
Hey everyone; I’ve been looking for a zip or jar with the API javadoc for the MySQL Connector/J package, but I can’t seem to find it anywhere. Does anyone know if such a thing exists (it should, right?) and where it can be downloaded from? Thanks

have you tried looking in the connector/j zip?
Yes, but I couldn’t find it.
Not in the doc/ folder

main kb is a very old MS Natural
waz, I have one of those too. Don’t want to replace it.
(I ruined my spare with spilled beer, alas.)
that’s ms’s split style kb, right?
yeah
Their newer model doesn’t feel nearly as sturdy. Keys are shallower, with no mass to them.
i tend to prefer those too…. my fingers get cramped on the regular kbs
ditto
I don’t have pr3d4t0r’s dainty hands
aight, how many of you assholes are using model Ms? Show of hands? C’mon, let’s see those monster forearms.
i use them for curls at the end of a workout :-/
If I had my way and some mechanism to connect it and work well with a Mac, I’d be using an IBM clicky 101 keyboard.
I’d rather use that than the Keyboard.
But given the choices, this is much better than the old white or black keyboards.
I never even open those

What’s the time cost of computing arcsines?
relatively not cheap
org.apache.jasper.JasperException: Cannot find any information on property ‘id’ in a bean of type ‘product.ProductBean’ — any idea why im getting this ?
Does it use numerical methods?
as compared to say, primitive math
probably. the source for Math.arcsin() is out there
er, fine. Math.asin()
pastebin~
can’t the FPU calculate it?
dunno. i’m not up on my assembly or cpu/fpu capabilities
I’m not sure, but I think it wants to find a property called “id” in your ProductBean class
I want to get the source code. Should I get the 100M+ source jar or the 2M Binaries for source?
i think it’s expecting a getid/setid method pair
binaries != source
getId and setId, I’d say
does it assume camelCase? (never done beans)
in my experience, yes
sup nzuhdi
http://papernapkin.org/pastebin/view/1289 here’s the bean
hey dude
I was just wondering if they have some good compress on the source. When I go to the source page. I saw “JDK Binaries for Source Build 6u2″
which project has 100M+ source and 2M binaries?
binaries are the programs/tools you run. they are built from the source
jdk, although i don’t remember seeing a…oh wait, the online installer
that’s not your real class, is it? Those imports are really suspicious if it is.
opss, ignore those imports
http://download.java.net/jdk6/
those are probably binaries used for building the source; the jdk binary download is 60MB+
maybe. any way, I’m downloading the source jar.
and the source download is 100mb
mainly because it includes source for windows, linux, and mac
Any good ideas on setting up Eclipse to find the source whenever I want it?
set it up in your prefs-java-installed jre’s
if you just want the api sources, they’re included in the binary jdk download
are they? i didn’t see them last time i installed
I want the source for arcsine
the page you were looking at has the sources for the jvm
yes, src.zip
hrmm, coulda sworn i put that there post-install. *shrug*
Math.asin calls StrictMath.asin which is a native method
really? that’s…interesting
oh…
it’s probably implemented in C
I added it to the place but F3 can’t find it
you told eclipse to attach the source to the system libraries?
What’s up?
I did what you told me prefs-java-installed jres
Oh no. When I open that page again, it disappeared from the jre list
that’s because it’s not a jre. you need to edit your installed jre
pr3d4t0r, oh nothing
How to edit it?
I see…
No. It still can’t locate it
oog. the strictmath implementations make my head hurt
select your installed jre. then look to the right
why? they’re so straightforward, just calling native methods
no, i mean the native methods
Do I need to add “source attachment” to each of the jars in the list?
yes
well, that’s just like jni
does jni make your head hurt?
no, complicated maths do
haven’t found any complicated maths yet..
still looking for the asin impl.
even a naive implementation of asin should be constant time, with a fairly large constant factor, at least. The constant factor depends on how many terms of the taylor series you use.
you might find it easier to profile than to read the sourd
source
It doesn’t work. I can see the source jar in the “attached source”, but F3 can’t locate it
