Symptom

The call fails and returns the following root cause, which points at missing XOM classes, although those classes have been deployed using the managed XOM feature:

Cause: java.lang.RuntimeException: java.rmi.RemoteException: CORBA NO_IMPLEMENT 0x4f4d0001 No; nested exception is:
org.omg.CORBA.NO_IMPLEMENT:
SERVER (id=4773e3aa, host=myhost.com) TRACE START:
   org.omg.CORBA.NO_IMPLEMENT: The sender's class RMI:test.MyParameterClass:1C07FA96BB0B7F99:1461E0CFE4DEDE78 is not present on the local classpath, and the class is not marked as truncatable, so it cannot be unmarshaled.  vmcid: OMG  minor code: 1  completed: No
