[jboss-user] [EJB 3.0] - Can a Stateless bean make a call to an entity bean to persis

Hi All , I am facing a problem in trying to put a call from a Stateless bean to an entity bean to persist an object . The beans are packed in an ear file and have been deployed on JBOss Server 4.xx . When I make a call to persist the entity bean object then it throws up an error as this : javax.persistence.PersistenceException: Exception [TOPLINK-7060] (Oracle TopLink Essentials - 2.0 (Build b41-beta2 (03/30/2007))): oracle.toplink.essentials.exceptions.ValidationException Exception Description: Cannot acquire data source [java:/system].
