Question

When I deploy my app, it works perfectly until I make a change, save, and netbeans hot deploys the application. At this point I get an unknown entity bean class error on a class that has the @entity and it’s included in my persistence.xml. When this happens, anything dealing with jpa stops working. Only if I restart the server will my jpa stuff start working again.

If I turn deploy on save off in my project and I only manually save and deploy I get the same results.

Is this just a netbeans/glassfish error? Or is there something wrong with my jpa setup?

Exception

java.lang.IllegalArgumentException: Unknown entity bean class: class amc.nase.idms.persistence.model.SecSession, please verify that this class has been marked with the @Entity annotation.

Answer 1

The issue is the old persistence unit with references to the old classes is remaining after your redeploy. Ensure the old EntityManagerFactory is getting closed. Glassfish should handle this for any managed factories such as in a SessionBean, but if you are managing your own factories you need to ensure these are closed.
