Hi, some users of (Apache) Openmeetings report following exception to our mailing lists:
*javax.persistence.PersistenceException: Found 'javax.persistence.provider' property in the map but the value is not a String. Found object : 'null'.* You can find hardly anything about this exception in the net and I tested on various platforms ... never had this issue. Is there a known problem or root cause for this exception? It seems to me like a problem with finding the persistence.xml. Thanks! Sebastian
