If I just run the program without debugging, I get the classic:

Java Virtual Machine is IBM Technology for Java. PID(4135)
JVM properties were loaded from a properties file.
Java exception received when calling Java method.
Application error. RNX0301 unmonitored by .....

The Java exception has this tidbit:

Cause . . . . . :   RPG procedure ...... received Java
   exception "java.lang.NoClassDefFoundError:
   org.apache.commons.logging.LogFactory" when calling method

Is org.apache.commons.logging.LogFactory also the method being dalled directly from RPG? (The method mentioned in the RNX0301 message following "when calling method")

If you were calling some other method, then the NoClassDefFoundError would have been received after the called Java method started. In that case, it might be useful to get an exception trace from Java. If you add this envvar, you'll get an exception trace printed to stderr.
ADDENVVAR QIBM_RPG_EXCP_TRACE value('Y')
