you mean don't mention J++ ?

Microsoft trying to implement java..

twice

That went *real* well

im not very used to jave, i need some obj to put inside my JPanel that reads html and has some sort of link and navigation functions..is there any? simplest to use would be nice..im using JEditorPane but i needed atleast some sort of navigation

Yeah ><

~~litb bomb

litb, javabot drops a humongous exploding turd on bomb

lol I was close

lol

haha

thanks javabot, noted

donpeyote: java's built-in HTML components are very limited right now. They're adding a component specifically for rendering HTML in the next patch or 2, but right now you'll have to make do with a third-party component or (i think) a JEditorPane

i just dragged JEditorPane right form the toolbox and setPage(..) and it works fine all i need now is the links working...its just some local html

donpeyote: it would be better just to launch an external browser

dragged from a toolbox?

matisse, I expect

ohh in an IDE

yeah im using netbeans....i really dont like it but...im not a java coder

donpeyote, you're writing a webbrowser and you're not a java coder?

no no i just need to display some html inside the app

writing a webbrowser must be painful

donpeyote: if you're dead set on embedding your html in your app, take a look at http://lobobrowser.org/index.jsp or http://mindprod.com/jgloss/htmlrendering.html

donpeyote, as Sou|cutter has said a few times, just launching an external browser would be better

I wrote a WYSIWYG html editor in java back in the 1.3 days.. it was hell

ouch

all i need is display wich i got already ...now i see the html page and underlike blue links and when i click them setPage no another..i dont know if its easy

Sou|cutter: you poor thing

*underline

svm_invictvs: I want a cookie!

~boost

svm_invictvs, I have no idea what boost is.

lol

tactics gives Sou|cutter a "chocolate chip" cookie

donpeyote: again, take a look at the links I gave you

:D

the chocolate chips are DEFINETLY chocolate, and not rat turds.

~boost4java

svm_invictvs, I have no idea what boost4java is.

There's boost for java?

no

lol

xP

But there needs to be, god damnit!

lol

Dont see how it would help anything

svm_invictvs is a huge fan of boost

;D

Doesnt java's std lib have like 80% of what boost has?

and more

well yeah

but i mean

tactics: It also cuts Julian Fries!

out of boost features

svm_invictvs: :p

oh man

Boost exists because C++ never had a decent stdlib

It's my b'day coming up.

tactics gets svm another "chocolate chip" cookie

Fanook, uhuh

so a friend of mine bought me a "gag birthday gift"

oh noes

russian bride?

I'm really hoping it's not an effigy of me on fire.

lol

*shrug*

'cause I kinda thought she was mad at me last time I talked to her.

:(

hey guys

hey

my friend thinks im always mad at him.. whenever i point out a flaw in C# he takes it personally as if i'm insulting him

hey trend

tactics, heh

you prefer java over c#?

i'm learning c# now.. i really like it

Both languages have their merits.

uhu

:/ I just wish I could program in one.. but seems like I have legacy code that requires one language..or an API that requires that.. or webcode that requires php

~point

I guess the factoid 'references are pointers' might be appropriate:

svm_invictvs, references are pointers is http://java.sun.com/docs/books/jls/third_edition/html/typesValues.html#106237

~point is <reply>Get to the bloody point already.

Okay, svm_invictvs.

~point

Get to the bloody point already.

lol

heh, urgent to answer some questions, no?

we have a pretty low nattering threshold here

ok.. really stupid one.. I have always make objects out of classes. .but can you make an object out of just a function? example.. when I create a new project, It creates code like this:

nattering?

~dict nattering

svm_invictvs, dict nattering is http://dictionary.reference.com/browse/nattering

heh, actually that conv was interesting to me.. was talking w/ someone earlier about it

http://pastebin.com/d6c44a47f

i'm sure it was interesting.

here it comes

~turd

I guess the factoid 'turdbreath special' might be appropriate:

svm_invictvs, turdbreath special is when I fail to to run `yum update` to patch a vulnerability that's been known about for months

Where's the exploding turd?

so in public static void main... I have: main myMain= new main(); which creates a new object of main()

is that the correct terms?

yes

so you can create an object of a class or a function :/

you can create an *instance* of a class.

ok

why would you want to be able to create an object of a function?

i wouldn't.

yeah, I cannot see any upside

ok, cool. back to nattering

:)

thanks for your input

well, one upside would be passing a method (or a list of them) to an event handler

someone of here could explain me the term, programming an interface?

hi java

on an off note Jetbrains seems to have removed "Rename to Groovy" from the dropdown menu in Diana :<

that's, in part, what closures would bring

~tell josefig about interface

josefig, interfaces is http://java.sun.com/docs/books/tutorial/java/concepts/interface.html

like passing around a function pointer?

still talking about closures

passing around a method?

cheeser, ah ok

Myoma: mmm yeh

java doesn't have closures

not officially

but it does have a prototype which can be used :)

is it any good

decent.

I wrote a simple swing app using it

cheeser, yes i know what it is, but i don't know the term, the concept "programming an interface", i'm looking for an answer in google, but i have not found it yet.

if you know what it is, that phrase would make sense to you

josefig: where you basically program based on a contract ie all methods defined in concrete classes match your interfaces

you're probably thinking "programming *to* an interface"

so you can pass in say a List vs an ArrayList (prime example)

you're not bound to one impl.

josefig: do you understand?

r0bby, actually no.

Interesting threading issue for y'all. I need thread A to wait for B and C to finish, but if either B or C errors, A should know immediately so that it can also die a quiet death. Any ideas how to do that?

B/C tell A about the failure

or A checks the final state of B/C before doing it's thing.

really, it's not that hard. just think the problem through.

ja, pretty straightforward.

josefig: the idea is that you should write your methods to take the least specific class you need to have the functionality you desire. For example, if you need a list, write your method to use a List instead of any specific implementation. That way if you need to change the implementation later, you don't have to change nearly as much code

well, this actually operates on a more complicated dependency graph

this is what i mean: http://pastebin.com/dce022be

A depends on B which depends on C and D, and D depends on ...

which is why paraphrased questions suck

fair enough.

josefig: okay, so what's your question?

let me see if one of the specialized synchronizers will do this efficiently

i don't understand the concept "programming an interface"

then you don't understand interfaces despite your claims otherwise

have you read the Sun tutorial on interfaces?

yes

then tell us which part you didn't understand

read it again.

~interfaces

Fanook, interfaces is http://java.sun.com/docs/books/tutorial/java/concepts/interface.html

i suggest you pick up head first java

ok

in thread A, while (status != RUNNING ) { wait(); } ?

*shrug*

Doesnt' seem that hard.

cooperative multithreading!

hm. looks like a Latch is what I need

Latch?

~javadoc Latch

I don't know of any documentation for Latch

anyone used any of the java workflow engines?

hi gambler

hi Myoma

~tell gambler about anyone

gambler, Instead of asking whether anyone works with something you need help with, please save time by asking your actual question. If someone knows and wants/has time to help, perhaps he/she will.

what is the best java workflow engine

why is it the best

drools

~next

Another satisfied customer. Next!

cheeser, how much time do I have to invest to get started

no idea

more than I have i'd bet

8^)=

25 years to life :>?

ok np

can you guys tell me your top 5 java development tools?

svm_invictvs: a Latch is a concurrency construct.

gambler: google?

~javadoc CountDownLatch

Fanook, please see java.util.concurrent.CountDownLatch: http://java.sun.com/javase/6/docs/api/java/util/concurrent/CountDownLatch.html

Fanook: Yeah, I know what a latch *is*

based on a condition variable.

im talking about things like ides, debuggers, log viewers, etc. excluding eclipse, eclim, chainsaw and lumbermill all of which Ive evaluated

Fanook, omg i found the answer, damn it, next time i'll read carefully thx.

~thx

http://www.thx.com/

lol

~reading++

reading has a karma level of 6, cheeser

Doctor Robert!

present

lol

r0bby: are you a beatles fan?

no

can some one help me setup envirmental variables

by convetion, only final static varibles are named in uppercase, right ?

:(

~tell waddo about getstarted

waddo, getstarted is http://java.sun.com/tutorial/getStarted

well seems like im paying someone 600$ to fix my java bug, someone should of stepped forward, id much rather have given it to someone from this room :(

jowvez: What about enums

tty1: Why don't you fix it yourself?

Myoma: been working on it for days, and im behind schedule, dont have the time...

Myoma: besides, might just need a fresh new pair of eyes

jownez: by conventions, constants are in UPPER_CASE

tty1: What is the bug?

yeah and what qulifies a var as a constant ? only final ?

final, immutable, generally static

final != constant

so final static

Myoma: its not a bug, but unexpected behavior (it isnt producing the output image it should, and is runnign 100x sloer than the C# working version)

tty1: If I fix it will you give me £300?

jownez: no, constant requires immutability. final and static are java-isms that make it more efficient

Fanook: ok thanks for the explanation

Myoma: too late now, i announced it to the room several time sbut no takers, but if he doesnt get it your welcome to try next (or you can try too and if you get it and he doesnt youll get the cash if you want but thats a risk on your part)

why dont you see hu gets first

=]

ok

my javac.exe is saved to

D:\Program Files\Java\jdk1.6.0_07\bin

so what do i cchange path to

tty1: you ran it through a profiler, right?

waddo:cause i already gave the ok to the other guy to try and to give him 600$ if he fixes it.. i cant change the terms now

Fanook: yup

~tell waddo about getstarted

waddo, getstarted is http://java.sun.com/tutorial/getStarted

waddo: win or unix

lol

nice question ;)

i already doe that

k, add ;d:\...

then you should know what parts of your program to look at

waddo: some free advice. Get rid of the spaces in your path. It will make things much easier

cheeser nods.

Fanook: not exactly.. unless im reading the profiler wrong all the parts of the code that should be slow are, and the parts that arent, arent... its just that its slower than the c# version.. the only thing ic oudl guess at is that floating point math on java is 100x slower but that seems like too big of a difference to me

http://nathan.pastebin.com/d71c1b0b6

i get that error

when i try and run something

Myoma: its opensource if thats any incentive to ya

?

http://nathan.pastebin.com/d71c1b0b6

tty1: I am curious why there is this much money flying about over an open source program

;D:\pascal\bin\i386-Win32;D:\Program Files\Java\jdk1.6.0_07\bin

that is my path

is that write?

no

whats wrong wrh it

Myoma: because its going to change the world in a serious way, so its worth investing in :)

tty1: Cool, what does it do?

it has unquoted spaces in it

Myoma: and technically its my company thats paying, i jsut own the company :)

Myoma: Artificial Intelligence

wow

so how do i fix tha

%20?

" "

Myoma: this particular problem is lossy image comrpession using ARtificial Neural NEtowrks (jsut a demo app so very simple, later willb e adapted into a benchmark)

tty1: Shouldn't that sort of thing be done in C or Lisp so it's really efficient?

Myoma: there are C/C++ and c# and java, and java via JNI prots of it actually

Myoma: so C/C++ is certainly one side of it

interesting

Myoma: but this particular bug is in java

the anti8ve java version that is

*native

Myoma: interested? or should i just hop in the shower and figure your not?

tty1: I want to look at the code tommorow or something if you are on I will ping you

Myoma: ok, or jsut go to the site... http://www.syncleus.com/dannProject/index.jsp

the svn has the latest code

dont us ethe RC thats outdated

what does this thing actually do?

that depends on what thing you're talking about

ok

it cuts through aluminum cans and the slices tomatoes!

so how did ou lot learn java

self-taught primarily

yes but what stuff did you use to learn the sytax and type declaration stuff

the javadocs

core java (1st ed)

i learned C/C++ first

hi, can i use OpenGL with Java? or it's just for C/C++?

~gl4java

Fanook, gl4java is OpenGL for Java at http://www.jausoft.com/gl4java.html

~jogl

cheeser, jogl is a JNI binding of the OpenGL 3d Graphics library. Great for 3d games in Java. https://jogl.dev.java.net/

rockyrock: java3d is a higher leve scenegraph too which is pretty cool if you dont want the low level nature of opengl

~java3d

Fanook, 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. For a nice alternative see JMonkeyEngine

I have a Computer Graphics course in my University, in the course my instructer use OpenGL with C

i currently use lots of java3d to do visualizations (3d graphs, ANN topology etc)

i don't know what's higer and lower leve scenegraph!

rockyrock: im jsut talkign about a higher level of abstraction

rockyrock: with opengl you draw triangles at a time and basically draw the scene from the basics

~xml

Kalianyia, xml is http://www.w3.org/XML - XML stands for "eXtensible Markup Language". It looks a bit like HTML except that you can define whatever tag you want. Used to store hierarchical data of any kind into a standard format. See "xml parsing" for how to write or parse XML.

rockyrock: with a scenegraph the API handles taking care of some of the stuff like moving objects around or invoking animations, etc

~xml parsing

Kalianyia, xml parsing is best accomplished with XOM (http://www.xom.nu/ ), JAXB (http://java.sun.com/xml/jaxb/ ), JDOM (http://www.jdom.org/ ) or XmlMap (http://www.zwitserloot.com/java-boilerplate/mox ). If you like pain, you may wish to check out SAX or DOM (http://java.sun.com/xml/tutorial_intro.html ).

can u plz explain for me what's really the OpenGL?

~tell rockyrock about aolbonics

rockyrock, aolbonics is using unnecessary abbreviations such as 'u', 'r', 'ur', 'thx', etc. Using this language depicts you as an imbecile in the eyes of the helpful regulars in this channel, and is generally not tolerated to avoid the level of discourse devolving towards something like this: http://tinyurl.com/35nm3k . Additionally arguing about this rule will get you nowhere except banned. Have a nice day!

has anybody taken a Computer Graphics course?

12 years ago

Any particular XML parsers recommended over others as a commonly accepted standard? (XOM, JAB, or JDOM)?

so what;s about?

~xml

Fanook, xml is http://www.w3.org/XML - XML stands for "eXtensible Markup Language". It looks a bit like HTML except that you can define whatever tag you want. Used to store hierarchical data of any kind into a standard format. See "xml parsing" for how to write or parse XML.

meh

~xml parsing

Fanook, xml parsing is best accomplished with XOM (http://www.xom.nu/ ), JAXB (http://java.sun.com/xml/jaxb/ ), JDOM (http://www.jdom.org/ ) or XmlMap (http://www.zwitserloot.com/java-boilerplate/mox ). If you like pain, you may wish to check out SAX or DOM (http://java.sun.com/xml/tutorial_intro.html ).

yes i already did that about 1/2 a page up

I just want to know what the pros in here recommend / use.

what Computer Graphics is all about?

i use dom4j

rockyrock: do you have a java question?

i personally prefer aolbponics and suggest you continue to use it (unless its a bannable offense) :)

Kalianyia: sjsxp

i asked that question cuz my prof will use OpenGL with C, but I'm a Java programmer and i want something realtive

Kalianyia: unless it can be very easily mapped to objects then xstream

~tell rockyrock about aolbonics

rockyrock, aolbonics is using unnecessary abbreviations such as 'u', 'r', 'ur', 'thx', etc. Using this language depicts you as an imbecile in the eyes of the helpful regulars in this channel, and is generally not tolerated to avoid the level of discourse devolving towards something like this: http://tinyurl.com/35nm3k .

xstream++

~~rockyrock jogl

rockyrock, jogl is a JNI binding of the OpenGL 3d Graphics library. Great for 3d games in Java. https://jogl.dev.java.net/

ok thnx

xstream rocks.

cybereal: i already shared that once.

and the aolbonics link

i still say aolbonics is prefectly ok (again unless its bannable)

it would seem the spaghetti is not quite done

cheeser: not in my backlog *shrug*

before you joined.

cybereal n ods

ah so you did :P

tty1: it's a channel rule, good as anything bannable

tty1: argue and well you know :P

if its a channel rule then id follow it for the sake of being a rule, but it doesnt mean i have to agree with it :)

cheeser and cybereal: thanks for the feedback

that's right you don't

and you think aolbonics are ok because you're an idiot.

But repeatedly notifying us about the disagreement isn't going to win any friends either

cheeser: hey, thats as good a defense as any :)

8^)=

the wookie defense++

lol

kinda like... repeatedly telling a jewish person that you think eating pork's just fine

cybereal: friends are overrated :)

cybereal: that's bad?

8^)=

Yep :p

aolbonics are highly annoying and distracting

(to me)

javabot: Myoma++

oh my ..

this is fun let's all join in

~r0bby++

r0bby has a karma level of 19, Fanook

oh shit

now you feel like an ass, don't you?

I just saw the irony.

I hope you dont use any abbreviations then. Abbreviatons=aolbonics

~r0bby aolbonics

I guess the factoid 'r0bby wisdom' might be appropriate:

cybereal, r0bby wisdom is captured by: http://eugeneciurana.com/.../view_photo.php?set_albumName=Humor&id=20030723this

fail!

missed a ~ but it's ok

cybereal: i dont mind beign picked on, it usually means i said something that made sense :)

tty1: you smell like ass

Yes, all abbreviations are aolbonics. Remember to spell Java Virtual Machine out each time.

hehe

tactics: wrong

yeah when I say something that makes sense usually people attack me

I vote next person to even remotely argue the aolbonics rule be banned (or at least kicked)

of course my vote has ZERO merit but eh it works

cheeser: tactics: 'You are wrong'.

r0bby: I think you remotely argued it just then

anyway...

So, how about some java

or another 'rita...

Howsabout another flame war?

YES...give r0bby alcohol

I could use a whiskey sour for this headcold

i was wondering when the topic nazis were comming ::salutes the java flag::

cybereal: or just whiskey

A 'rita? How dare you sit in ##java and not have a nice cup of hot coffee!

I would love some coffee

not at 10pm ...

wyvern: I don't enjoy whiskey neat

I wish I also finished writing this method .....

tactics hopes noone notices that his "coffee" is infact hot chocolate...

wyvern: maybe single malt warmed

but then I may as well just have some proper sake

what int he world was that for?

cybereal: what about rum?

pass

Have you had *good* rum?

Bad rum tastes like poison

good rum tastes like port

that's a good question, I wouldn't know

nobody I know is a real rum drinker

I have 6 good rums

I'm a vodka drinker, my pop-in-law is a whiskey drinker

I Drink soda.

yo ho ho?

Rums aren't popular, so they're really cheap

A very good rum can be had for $30-40.

tty1 wanders off wondering why he was kicked

tty1: I think it obvious

Scotch is prestigious so its price is jacked way up

cybereal: i have no idea, im not talking aolbonics, or even offtopic (unliek the rum and scotch convo going on)

Tequila also has that happening over the last several years as distillers have started making quite excellent tequilas

~interesting

this is all very interesting (not really) but please take it somewhere else.

cybereal: hell otu of everyone im the best behaved

cheeser: okay, okay :)

tty1: did you read the kick message?

cybereal: yea but didnt make any sense.

cat /dev/urandom >> /dev/tty1

tty1: you must be joking

cheeser acquits tty1 ?

can I use a ResultSet even after I close() the db connection?

tty1: *you* made the comment about saluting first

~tell trend about tias

trend, Try it and see. You learn much more by experimentation than by asking without having even tried.

or should I move the RS to somethign else

no im seriously confused.. cause i said they wanted us to stop being off topic?

cybereal: yea but whats that have to do with anything?

yes and you said it in a sarcastic way

tty1: the quit message was salute

how do you tell a Runnable to yield some cpu?

rullie: you don't

didn't want to, because I will have to rewrite some code

rullie: Runnable is just an interface

write better algorithms

trend, just make a testcase

rullie: you ask it to wait, assuming it lets you

cybereal: yea but what i said witht he salute in it wasnt anything bannable, thus the confusion

tty1: you didn't get banned did you?

Fanook: i tried, gave me illegalmonitor something something

psst the answer is no

cybereal: no but a kick is a warning, meaning i should understand why i got kicked shouldnt i?

no

tty1: a kick is just a kick

you shoudl just forget it happened

rullie: the thread you want to pause has to call .wait(), and it can only do that in a synchronized block/method

thats fine by me, im not upset or anything, just wanted to know what i did wrong so i dont do it again..

~javadoc Thread.yield()

cybereal, please see http://java.sun.com/javase/6/docs/api/java/lang/Thread.html#yield()

cybereal points up

Fanook: is there some better way to do this? I'm using ExecutorService

thread.yield has no guarantee of actually doing anything

what should I moe the ResultSet to so I can conn.close (); ?

it's up to the implementing jvm

well whatever ill jsut ignore it, i suppose if cheeser thought it was important for me to know he would have said so..

just a List is the norm?

it might, for instance, totally ignore yield()

wyvern: the same terms for every other threading command

ill see you guys around headed out for a bit enjoy the java

trend: some collection that makes sense

cybereal: yeah, but Thread.yield() got special treatment in JCIP to say it's not to be trusted, so I thought it was worth a mention

cybereal: it's not a thread though, it's a Runnable

rullie: everything executes in a thread, Runnable is just an interface

oh, ok.. so just depends. thanks for your input

rullie: I see it's clear you have no understanding of threading and you ought to read JCIP

cybereal: i'm giving the runnable to a executorservice

rullie: yes, even better to question why you'd want to yield time then, as that's the job of the executor service

cybereal: right, so i'm asking if there's a better way to do this

rullie: well, you haven't said what you're trying to do at a high level

rullie: well in my case instead of waiting, I split up my task into multiple steps and each step schedules the next step in the service when it's done to keep tasks processing flowing fairly

run a bunch of runnable with a execturoservice without sucking up 100% cpu

rullie: for example, one common task I do in an ES is sending messages to clients, which means looping, which means it could take up the thread in that pool for forever potentially

no, i don't need synchronization between the runnables, i just want them to run

rullie: so to maintain fairness each loop is a single task and at the end, it's rescheduled, the next execution checks to see if it needs to run again and exits if not without rescheduling

rullie: what task are you trying to perform that is benefited by not using up CPU?

rullie: you could write your own executor that delayed between tasks or something

eh

provide a thread factory that made low priority threads perhaps

generally if you have a job to do you should do it as fast as possible...

there's no way to tell executorservice to be easy on the clocks and yield some for its friends?

write your own

they made AbstractExecutorService for that reason

heh yes could do that

wyvern: yes, that would be nice except i have other jobs along with it

so i gotta roll my own?

I have a task queue that allows me to schedule the task in the future, so the executor service won't get the task til it's supposed to be run

could work for you to do it that way

yeah, a custom queue might be enough

i was looking for an easier way...

only release x tasks per second

i guess there is no easier way then ...

well, you're looking to do a pretty unusual thing, so you're gonna need to do SOMETHING custom.

rullie: the problem with your insinuated solution is that it consumes a thread, when it really shouldn't

plus it binds a behavior to the wrong domain of concern (the task shouldn't care the performer of the task should)

i think you guys are complicating my question...

can I "run a bunch of runnable with a execturoservice without sucking up 100% cpu"

easily

well, are they CPU intensive?

...

the runnables
