How to execute GoesCollaboration Application

Dear whom it may concern,

I installed VisAD ver.2(Java Version) in the  Windows98. When I ran
the execution file "java" like "java GoesCollaboration", the error
messages were as follows;

Exception in thread in "main" java.lang.NoClassDefFoundError: GoesCollaboration
(wrong name: visad/paoloa/GoesCollaboration)
 at java.lang.ClassLoader.defineClass0(Native Method)
 at ....
 at ....

Could you let me know how to run it?
Thank you very much.

S. Ryu
