Bernard Labno commented on AS7-3423:
------------------------------------

Scott I've tested branch AS7-3423_deploymentWithJavaXPersistence_4 but it didn't solve the problem to the end.
I'm running seam2 on as7 with hibernate3 bundled with app. If I add ehcache as second-level cache i get this exception:

Caused by: net.sf.ehcache.CacheException: Another unnamed CacheManager already exists in the same VM. Please provide unique names for each CacheManager in the config or do one of following:1. Use one of the CacheManager.create() static factory methods to reuse same CacheManager with same name or create one if necessary2. Shutdown the earlier cacheManager before creating new one with same name.The source of the existing CacheManager is: DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ]
at net.sf.ehcache.CacheManager.assertNoCacheManagerExistsWithSameName(CacheManager.java:457) [ehcache-core-2.5.1.jar:]
at net.sf.ehcache.CacheManager.init(CacheManager.java:354) [ehcache-core-2.5.1.jar:]
at net.sf.ehcache.CacheManager.<init>(CacheManager.java:242) [ehcache-core-2.5.1.jar:]
at net.sf.ehcache.hibernate.EhCacheRegionFactory.start(EhCacheRegionFactory.java:70) [ehcache-core-2.5.1.jar:]

It looks like the persistence unit is being initialized twice. I'm attaching both my server.log and sample project sources.

> If an application deployment contains its own copy of a persistence provider, make it possible for the application to access the persistence provider via the javax.persistence.Persistence.
