java vm not working, appletviewer does...

["gl :)" <gl@despammed.com>]

Hello everybody :)

I've got great headhaces trying to setup Compaq JDK 1.3.1 on my PWS 
runnind debian SID.
At first sight my problem seems a classpath related faq, but I cannot 
find a solution anywhere.
My CLASSPATH is set to 
/usr/java/jdk1.3.1:/usr/java/jdk1.3.1/lib:/usr/java/jdk1.3.1/jre/lib:. 
which should be fine.

When I try to run the HelloWorld code...
  gl:~/java/Hello$ java HelloWorld.class   Exception in thread "main" 
java.lang.NoClassDefFoundError: HelloWorld/class

The HelloWorldApp applet code instead runs fine in the jdk 
appletviewer...

What should I do?

Thanks
gl :)
