HibernatePersistence does not play well with other PersistenceProviders ----------------------------------------------------------------------- Key: EJB-247 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-247 Project: Hibernate Entity Manager Type: Bug Components: EntityManager Versions: 3.2.0.ga Environment: all Reporter: Jeff Drost When HibernatePersistence is called to create a EntityManagerFactory, Ejb3Configuration.configure() is called. If configure() determines that persistence.xml refers to a non-hibernate provider, then it is not used, and null will be returned. HibernatePersistence never checks the return value of configure() and then calls buildEntityManagerFactory() - which will throw an exception. This stops javax.persistence.Persistence from searching for another provider. I would think HibernatePersistence should check the return value of configure() and only call buildEntityManagerFactory() if the result is non-null. Otherwise, null should be returned. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
