    Could not enlist in transaction on entering meta-aware objec

    Jeff Newbie

      Hello all,

      I'm really really stuck on a persistence issue and would like some help please.

      jboss-4.2.2.GA
      Hibernate 3
      MySQL 5.0

      I have an EJB that is a SessionBean & TimedObject.

      It wakes up every 200 ms to check a directory for any files to process.
      (XML files)

      I'm using a <local-tx-datasource>.
      I've tried using <no-tx-datasource>, but not all the data gets saved to the DB (no error messages).

      The EJB has no static member varibles.
      The EJB makes a call to another EJB to do the actual persistence.

      This is the statck trace I get...
