[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5304) Deploying Hibernate 3.5 in isolated classloader in AS 5.1 fails

[Galder Zamarreno (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=37537#action_37537 ] 

Galder Zamarreno commented on HHH-5304:
---------------------------------------

So, if anyone ever wanted to get Infinispan 2LC to work on AS 5.1, it would be easier to attempt to port Infinispan 2LC to Hibernate 3.4 instead? I don't remember any major changes in terms of caching since 3.3.

> Deploying Hibernate 3.5 within an isolated deployment in AS 5.1, where Hibernate 3.3 or 3.4 runs, fails with:
> 3:29:34,255 INFO  [PersistenceUnitDeployment] Starting persistence unit persistence.unit:unitName=InfiniSeam-ear.ear/InfiniSeam-ejb.jar#InfiniSeam
> 13:29:34,305 ERROR [AbstractKernelController] Error installing to Start: name=persistence.unit:unitName=InfiniSeam-ear.ear/InfiniSeam-ejb.jar#InfiniSeam state=Create
> java.lang.ClassCastException: org.hibernate.ejb.HibernatePersistence cannot be cast to javax.persistence.spi.PersistenceProvider
> Taking in account that org.hibernate.ejb.HibernatePersistence extends javax.persistence.spi.PersistenceProvider, this would appear to be an issue of the first class being loaded with a CL and the second one with a different one.
> Since org.hibernate.ejb.HibernatePersistence is something that's defined in the persistence.xml, there might be a change that this class is loaded from the wrong place rather than the .ear file (This is just a hunch though):
>       <provider>org.hibernate.ejb.HibernatePersistence</provider>
