    public QueueRequestor(QueueSession session,
     Queue queue)
     throws JMSException 

    Constructor for the QueueRequestor class.

    This implementation assumes the session parameter to be non-transacted, with a delivery mode of either AUTO_ACKNOWLEDGE or DUPS_OK_ACKNOWLEDGE.

    Parameters:

    session - the QueueSession the queue belongs to

    queue - the queue to perform the request/reply call on

    Throws:

    JMSException - if the JMS provider fails to create the QueueRequestor due to some internal error.

    InvalidDestinationException - if an invalid queue is specified.

• Method Detail

  • request

    public Message request(Message message)
     throws JMSException 

    Sends a request and waits for a reply. The temporary queue is used for the JMSReplyTo destination, and only one reply per request is expected.

    Parameters:

    message - the message to send

    Returns:

    the reply message

    Throws:

    JMSException - if the JMS provider fails to complete the request due to some internal error.

  • close

    public void close()
     throws JMSException 

    Closes the QueueRequestor and its session.

    Since a provider may allocate some resources on behalf of a QueueRequestor outside the Java virtual machine, clients should close them when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.

    Note that this method closes the QueueSession object passed to the QueueRequestor constructor.

    Throws:

    JMSException - if the JMS provider fails to close the QueueRequestor due to some internal error.
