fact

Novell exteNd Application Server 3.7.4

Novell exteNd Workbench 2.0

symptom

Receive an error on the Application Server Console after a servlet calls an EJB

Error: "java.rmi.NoSuchObjectException: CORBA OBJECT_NOT_EXIST 9998 Maybe"

Error: "java.rmi.ServerException: RemoteException from the server; nested exception is:
java.rmi.RemoteException: Non-reentrant requirement is broken"

Do not receive the error message the first time that the servlet calls the EJB

The Enterprise Java Bean (EJB) appears to complete it's work and no exceptions are being thrown from the EJB. The correct results are returned

This Enterprise Java Bean (EJB) is a Stateful Session Bean

cause

If calls are made too quickly to the Stateful Session Bean, the "java.rmi.NoSuchObjectException: CORBA OBJECT_NOT_EXIST 9998 Maybe" error is received.

fix

Serializing the calls to the Stateful Session Bean will prevent this from happening
