 Post subject: EntityManagerFactory creation failed when webapp redeployed

Hi,

I'm using Hibernate JPA 3.2.1 with Glassfish V1. When I undeploy and deploy a new version of the webapp I got the error below. I have to restart the server instance after each re-deployment of the web application for EntityManagerFactory to be created properly.

Any idea why?

thanks.

Apaprently Glassfish mess up with the thread current class loader on redeployment

Here is the culprit line
Code:
         Enumeration<URL> xmls = Thread.currentThread()
               .getContextClassLoader()
               .getResources( "META-INF/persistence.xml" );

PS i seems you don't use the Java EE / JPA integration though
Are you creating your own EMF in your code (using Perssitence.createEMF)

PS: it should not fail either

Yes, I'm using application-managed entity managers. The service layer uses MyEntityManagerFactory to obtain EntityManagers. The line below is where I created the javax.persistence.EntityManagerFactory in MyEntityManagerFactory .

private static EntityManagerFactory emf = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT)

tmw, do you have any updates on this? I have the very same problem on glassfish v2-b33 and b41 as well with Hibernate EntityManager.

dyn, I don't have a resolution for this yet. I'm restarting the server instance every time I redeploy. I posted the same issue over at the glassfish forum, but haven't got a real resolution.

Maybe you should comment on the link above or create a new thread at the glassfish forum to rejuvenate this issue.

Okay. I'm trying to track down this issue with some other glassfish users/devs. You can see the according thread here: http://forums.java.net/jive/message.jsp ... eID=212150
