Setting Java PATH

[furryfren]

I am using Knoppix 3.8.1 and it is bundled with Java 1.4.2. I do not know how to uninstall Java 1.4 and since I need the new features of Java 1.5, I decided to install Java 1.5 over it (some of you may think its not a very good idea).

Now, when I run a java -version at the command prompt, it still says 1.4.2. So I explicitly exported the PATH of my new Java 1.5

"export PATH=/home/java1_5/bin"

After that "java -version" replies with 1.5, which is correct. However when I restart the shell, the PATH seems to be reset to its original state and won't recognize my Java 1.5!
Please help!

Prepend your PATH variable with that directory in your .bashrc file.

Redo your symlink in /usr/bin to point to your copy of the java.
