EJB programming & troubleshooting: CMT method with no trans-attribute specified

  1. CMT method with no trans-attribute specified (1 messages)

    what will the container default to in the absence of a trans-attribute for the onMessage method of an MDB? is it "Required" or "Not Supported"? thank you
  2. looks like the default is required. snippet from : http://java.sun.com/javaee/5/docs/tutorial/doc/JMS7.html#wp92011 --- To ensure that all messages are received and handled within the context of a transaction, use container-managed transactions and use the Required transaction attribute (the default) for the onMessage method. This means that if there is no transaction in progress, a new transaction will be started before the method is called and will be committed when the method returns. --- Bhagvan K http://www.jroller.com/page/bhagvank
