I am running an application that uses Hibernate on both a Tomcat server, and in a Jave GUI. The following code works fine on Tomcat, but fails with a MappingException on the GUI. I am wondering what I am doing wrong.

Transaction t = session.beginTransaction();
try {
session.save(job);
t.commit();
}
catch (HibernateException e) {
t.rollback();
throw e;
}
finally {
session.close();
}

Here is the stack trace.

ERROR [] - No persister for: com.onerealm.solx.wfg.run.WfgJob
net.sf.hibernate.MappingException: No persister for: com.onerealm.solx.wfg.run.WfgJob
at net.sf.hibernate.impl.SessionFactoryImpl.getPersister(SessionFactoryImpl.java:347)

at net.sf.hibernate.impl.SessionImpl.saveWithGeneratedIdentifier(SessionImpl.java:763)
at net.sf.hibernate.impl.SessionImpl.save(SessionImpl.java:738)

However, the startup log shows that Hibernate successfully read the mapping files.

Any suggestions will be gratefully received.
