I need help.

I just install Java on MPE/iX version 6.5
Used  JINSTJDK.INSTALL.JAVA  for the installation.

The Problem:   The "Exception in thread "main"
java.lang.NoClassDefFoundError".
Thrown if the Java Virtual Machine or a classloader tries to load in
the definition of a class  and no definition of the class could be
found.
The searched-for class definition existed when the currently executing
class was compiled, but the definition can no longer be found.

P.S.  I found three questions posted to the HP3000-L in the last year
asking about various incarnations of this exceptions but never any
answers.     Also nothing in the Java/iX FAQ on Jazz.
