Newbie question: Class path variables

[Jan Peters]

Hello,

I just encountered the following error messages compiling the java 
application jmousetrap-2001-09-13.
I guess, I just have to set the swarm paths right, but how does it work? 
I am not completely new to Linux, but my experience is limited. How 
should my profile file look like and which paths are crucial to set for 
programming Java Swarm applications?

Thanks in advance

Jan

And here are the error messages:
