In shell...

$ vi ~/.bashrc

Press 'a' on the keyboard to insert... and type in the following:

Code:

# User specific aliases and functions
PATH=$PATH:/usr/java/j2sdk1.4.2_06/bin
export PATH

**NOTE: Your path my differ, depending on version and if you have SDK or just JRE. Please go to the /usr/java directory and right down the proper directory name and be sure to add /bin on the end**

Press 'Esc' to stop inserting.
Press ':' to bring up the vi command prompt.
Press 'x' to exit and save.

Now log out of KDE or Gnome and log back in.

In shell...

$ which java

Should return the path to your java install.

Type "locate java" and see what is returned. This should give you where java is installed.

Depending on your distro, it is likely to be /usr/local/java, /usr/lib/java or /usr/java.

Then open your ~/.bash_profile with your favourite text editor. Use .bash_profile rather that .bashrc, since .bash_profile is read on login, whereas .bashrc is read each time you open a shell. Add the following lines to .bash_profile:

Code:

export JAVA_HOME=/usr/lib/java
export PATH=$JAVA_HOME/bin:$PATH

(assuming that java is in /usr/lib/java. Substitute for where it is on your system)

I hope this helps
