How to interpret my stacktrace?

Question

I use IBM RAD 8 and deploy to websphere and then I get this stacktrace:

ERROR ArendeProcessLoginServlet:142 - Fel i ArendeProcessLoginServlet, performTask(): 
javax.ejb.EJBTransactionRolledbackException: nested exception is: javax.ejb.EJBException: See nested exception; nested exception is: <openjpa-2.1.1-SNAPSHOT-r422266:1141200 fatal user error> org.apache.openjpa.persistence.ArgumentException: The type "class se.prv.pandora.arendeprocess.entity.Anstalld" has not been enhanced.

    at org.apache.openjpa.meta.ClassMetaData

What does it mean? What steps should I take to resolve the error?

Thanks for any help

Looks like your model class 'se.prv.pandora.arendeprocess.entity.Anstalld' hasn't been ehnanced. See this link on how to enhance model classes in openjpa before they can be used by your application.
