Robert, I assume you've signed off and back on.  Once the JVM is
started, the classpath can't be changed, and you can't end the JVM and
restart it in the same job (at least
not reliably).

Did you specify the classes exactly the same in your RPG as you did in
your import statements in Java, with the package info (*JAVA :
'mypackage.mysubpackage.myclass')?

That's all I can think of that could be causing your problem.

When RPG starts the JVM, it just uses the CLASSPATH environment variable
when it sets up the parameters for the call to the JNI Invocation API.
I don't really know how this is actually used by JNI.
