[jboss-user] [EJB3] - Re: Why do EJBs share EntityManager instances

Kieran Simpson [http://community.jboss.org/people/kierans] created the discussion "Re: Why do EJBs share EntityManager instances" To view the discussion, visit: http://community.jboss.org/message/575802#575802 -------------------------------------------------------------- Doing some further digging around, the object that is being injected  into the DAOs is an instance of http://grepcode.com/file/repository.jboss.org/nexus/content/repositories/... org.jboss.jpa.tx.TransactionScopedEntityManager which is located in the jboss-as/common/lib/jboss-jpa-deployers.jar  JAR.  Looking inside the manifest, the JAR is at version 1.0.0 Looking at the source, it would appear as if the TSEM  class should be doing what I thought it should do; that is provide  EntityManagers which are only enrolled in the transaction that is  currently assigned to the thread. Still I have no idea  why when a transaction is rolled back in one thread all transactions are  rolled back.  Perhaps this is a transaction management issue rather  than an EntityManager problem. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/575802#575802] Start a new discussion in EJB3 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
