Java Package Help!

Does anyone know where I can find the following packages for Linux:

TurtleGraphics
TerminalIO
java.util
BreezySwing
Swing

I would prefer to have an rmp, self-extracting file. Either that, or a complete explanation with the packages explaining where everything goes. If you say to get the JDK, please don't, because I already had some memory problems with that (computer memory, that is). Thanks.

Well, that's too bad about your memory problems, because 2 of those are in the official Sun JDK (java.util and Swing). Maybe try one of the open source JDK implementations instead (kaffe, gcj, etc.).
If you explained what you were trying to do it would probably help with the number of answers.

If the memory problems are to do with Java running out of memory, then you might be able to fix that by adding the -Xmx parameter to your java command. This defines the maximum amount of memory that is available in the java memory pool. Its default is 64MB, and if your computer has a lot more than that you could get your application running by using a value of -Xmx512.

I'm not all that worried about the memory (I found out it was my trash bin sucking it up). Now I'm just concerned about BreezySwing and TerminalIO for Linux.

Then I don't see what the deal is, you just search for TerminalIO and BreezySwing and download the jar files for them. It isn't like you'll get rpm files that just have 1 or 2 jars in them. Do you want to use them for development? You still haven't explained what you want to do, so it isn't clear.

I've looked for them up and down Google, and all around the java.sun site. I don't see any pagckages for Linux. And I want the packages for Linux, buecause I don't know where the packages go. in /usr/bin/java?

What are these packages you want for Linux ?
Jar files a platform independant, so they would work for linux or any other platform.

Try following the instructions here, everything is explained.

That's not what I'm concerned about. I'm simply concerned about where the packages go. There are plenty of instructions for Windows, but I've scoured Google, and I don't see any for Linux.

Tux

With platform independent stuff you can put it anywhere you like. If it is just for you put it in your home directory. If it is to used system wide put it in any directory that is in your path.

I've put it anywhere I please since it's for personal use. Still, the compiler doesn't recognize TerminalIO and BreezySwing. Yes, I do say
import TerminalIO.*;
or
import BreezySwing.*
at the beginning of my program (outside the class declaration of course), but it just doesn't recognize the package.
Do I need to specify the class path? If so, please tell me how. Thanks.

That is what you are concerned about !

If you care to read carefully the above mentioned link, you'll find that the instructions are given for Linux too (i.e. Other Environments).
Well, I concede they aren't given clearly enough, so here the answer your are looking for:
copy these jars to your <jre-directory>/lib/ext directory.

It's a little strange, I know, but I'll post my own answer in this one (I don't know if anyone else answered it...sorry). For future reference, you need to create a CLASSPATH for the packages. I actually created an alias to make it easier. But, that's how you do it

Tux-O-Matic · 10-24-2006, 04:55 PM

Okay, maybe creating a class path didn't help. I know I'm annoying, but if someone knows what to do, please tell me. I've done everything I know how to do: try yum, unzip a package, download a birnary file, creating a class path, placing it in the java/lib/ext direcotry...
If anyone has had this problem and has fixed it, I would greatly appreciate it if you could tell me. Thanks so much.
