[phmkem]

Hi all

I am a Java Developer who is new to the Linux OS Altogether and cannot figure out how to configure the JRE I Believe my error lies in the class path variable because I keep getting Class Not Found Errors also I have no clue on how to setup the Applet Plugin.

Any Help is appreciated

Which IDE u intend to use?

For eg, BlueJ works with Sun Java only.
http://www.bluej.org/

Search and install JDK (Sun or OpenJDK) in System==>Admin==>Synaptic Package Manager.

Pls mention specific issues, if any.
