    MDB getting triggered before global transaction on client co

    Raja Sait Newbie

      I have a client that posts a message to JMS Queue and write a database record about the message in a global transaction by calling a method on stateless session bean.

      Associated with JMS Queue, I have a MDB registered to process the messages. In the OnMessage Handler I tried to update the database record with some status and proceed to process the message.

      The trans-attr on stateless session bean method is Required. The stateless session bean uses XAConnectionFactory and OracleXA classes to participate in global txn.

      I am seeing the message driven bean is invoked before the global transaction is commited to the database. As a result the database record is created after the MDB is invoked which results in some of the updates not happening in the database

      I am using JBOSS 3.0.2 version. Any ideas if this is a bug or something that I am doing wrong.

      Thanks in advance
