  1. How to handle transaction time out before timing out? (3 messages)

    Hi
    I have a Session bean (transaction managed by Container, Requries new) that uses JMS/MQ to get certain information from an IMS enviornment in a *synchronous* manner.So the bean writes certain queries to IMS on a queue and waits on reply queue.
    Sometimes it so happens that IMS does not respond quickly - for whatever reasons. In such cases the transaction times out and container(websphere) rollsback entire transaction. Is there a way to do something like this:
    Send message for IMS
    see if it had taken more than 30 seconds - if so, throw an application exception? with in the boundaries of J2ee specification?
    Thanks in advance

    Specify a timeout on the blocking receive call. Example

    Message m = QueueReceiver.receive(30000);

    if(m == null) // we timed out and rollback the tran

    Also be sure to have committed the tx where you send the original message, otherwise, it'll never get there :) You need two transactions, one to send and a new one to receive.
