I am a newbie to Linux. I tried setting environment variable using export JAVA_HOME=/usr/java/jdk1.6 but that was not permanent (i.e is was there for that terminal session). I want to know how can i set environment variable permanently in Fedora 13 just like we do in windows.After google search, some user suggested to edit bashrc and profile file for setting environment variables but above file contains some shell programs.

I've purchased a couple of books so that I can begin to learn JAVA. Finding recent editions is very challenging, so the books I found cover JAVA 5.0. I plan to go through all of the exercises in both books. Which version of Java should I have installed on my computer?
Should I install 5.0 so that the examples from the book will work perfectly? Will I run into confusing situations or problems if I try the example exercises using Java 6?

If you are interested, Java SE 6 Update 24 is available. The Check Java Version link in my signature will tell you if you are up to date or not. The Update Java Version link in my signature will tell you how to obtain and install the latest version. The 32 bit version install directions are on the left side of that page and the 64 bit instructions are on the right side.
Just remember to remove the current version before installing the new one as it says in the instructions. The remove instructions are below the install instructions. Also, in Step 9 - "Now you'll want to tell the system, that there's a new Java version available." See the note below it that says if you get an error upon entering the command once, enter it a second time. I have to do that and sometimes forget. Just thought I would mention that. These instructions are already setup for version 6 update 24, but they can be modified for any update and they will work. I have been using these instructions for a couple of years and they work.

I play this game called Minecraft, and I'd like to run the server package as well, but the server is laggy as hell. I did my research, and some people were saying that one of the problems was the Java version. They recommended rolling back specifically to 1.6.0_13, but they didn't say how. So I Googled for a tutorial on how to roll back Java in Ubuntu, and got nothing. So here I am.
I also learned that you can add some extra code into a Java run command to make it run off of a specified version, so I added this to the original command I have to run my server
Code:
-version:1.6.0_13 and got "Unable to locate JRE meeting specification '1.6.0_13'". So now I'm thinking that Ubuntu didn't retain any previous versions of Java. My second question would be, where does Ubuntu keep it's versions of Java, cause I'd just download that version of Java, put it where Ubuntu keeps it, then run that command again and hope it works.

I've made a linux app that I'm porting to win32 winth MinGW and MSYS. It's a ticker app that reads then renders a text file to a pixmap (a tall single-line image), then it kind of scrolls the pixmap by drawing a part of it to a drawing_area, using gdk_draw_drawable() within a timeout handler set by g_timeout_add().
The problem is it works fine on linux (the scrolling is really smooth and that's the goal) but the win version is choppy and uses at least 90% of cpu resources (vs 15% with linux) like there is a big performance problem. And I'm not even sure that double buffering is set. Is it related to some mingw config or drawing_area stuff or gtk for win?

I have a Sun Fire X4450 running RHEL 5.3. Attached to this server via FC is a Sun StorageTek ST2540 that allows additional storage capacity. In order to administer the ST2540, a software application from Sun (CAM 6.6) has been installed. Part of the install process for this application also installs Java JDK1.6.0_12 (64-bit).
However as we use this hardware as a database server, our database software will not install properly as it requires an earlier version of Java JDK1.5.0_11 to be installed. When I try and install the older JDK rpm package, RHEL will not let me. How can I get both versions of Java installed?

I downloaded Java into my home folder instead of downloading it in my usr folder because it wouldn't let me(even when I was root user). It is present in my home folder with its own directory, but I am unsure how to use it. I downloaded Java to try to play Minecraft, but when I open then .jar file with the directory nothing happens. The actual directory contains the following
folders:bin,javaws,lib,man,plugin,copyright,licens e,a read me file, thirdpartylicensereadme, and a welcome.html file. I don't like running Minecraft with OpenJDK because it lags tremendously and it won't close, and I heard the "real Java" runs it much better.Did I download it incorrectly, if so can you tell me how?

Groovy is an object-oriented programming language for the Java platform. I do not have experience in Java, only perl and shell scripts. Recently I have been asked to maintain a software written in groovy (also to make enhancements). So can I learn groovy without knowing java language. or isit I have to learn java before venturing into groovy.

You can install Java either using "Synaptic Package Manager" or using "apt-get install java-6-openjdk" command.Java will be installed to the location "/usr/lib/jvm/java-6-openjdk"Now open a terminal and type "sudo gedit /etc/bash.bashrc ".Append the following lines to the opened "bash.bashrc" file
"export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/"
"export PATH=$PATH:$JAVA_HOME/bin"
Save & close the "bash.bashrc" file
[code]....

Tomcat installation requires JAVA_HOME to be defined. In Windows it is straight forward. But in Linux binaries are in one folder and libraries are in other folder.
Is there a way to find out where exactly is JAVA_HOME?
