    public TopicRequestor(TopicSession session,
     Topic topic)
     throws JMSException 

    Constructor for the TopicRequestor 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 TopicSession the topic belongs to

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

    Throws:

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

    InvalidDestinationException - if an invalid topic is specified.

• Method Detail

  • request

    public Message request(Message message)
     throws JMSException 

    Sends a request and waits for a reply. The temporary topic is used for the JMSReplyTo destination; the first reply is returned, and any following replies are discarded.

    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 TopicRequestor and its session.

    Since a provider may allocate some resources on behalf of a TopicRequestor 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 TopicSession object passed to the TopicRequestor constructor.

    Throws:

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