First you can change the jre/jdk startup to actually set them :D

 

I used to do this with a particular jre which was needed by Oracle8i.

If I remember though if you have different ones you also need to set the linker libary path (LD_LIBRARY_PATH) or times might have changed :D

 

Second way is to do it globally in /etc/(something) .

Or you can do it per user

Depending on the shell/intepreter .. it depends on the scope you want to apply to it.

If you have different JDK versions you might want to just make a script that sets them seperately...

Or for per user .... It depends if you want them per interpreter loaded OR per user login... (i.e. you can bypass with su <user> instead of su - <user>

 

The man pages for the intepreter are the place to look.

man csh/sh/bash etc....

Im in Solaris mood right now and I remember the csh is the .cshrc or .login depending on scope but the bash stuff (is .bash_profile ) etc.

I don't wanna tell you wrong but man .bash_profile is a good start :D

you need to put it in the .bashrc file.

 

You (AFAIK) will also need to reboot after you add them to that file so that the changes take affect.

not reboot, just re-login

if u want to put variable for all users. u have to put them in /etc/profile or in /etc/profile.d/

Precisely! This came from Sun with instructions in their j2re file:

 

Create java.sh / java.csh (depending on shells) in etc/profile.d/ containing:

 

JAVA_HOME=/usr/java/j2re1.4.2_01

export JAVA_HOME

PATH=$PATH:$JAVA_HOME/bin

export PATH

 

(of course path in first line must match your system)

This works for all users.
