-------------------------------------
ritesh-
Mailing list or irc chat is a good place to go for answers like this. One
quick thing to look at is you may prefer using a MessageListener callback..
messages are just handed to a method for you and you don't have to deal with
any of the timing logic by hand. (onMessage()..)
Look into ".. implements javax.jms.MessageListener"
> issue with messageSelector

> Message is already there in queue (I can confirm with activeMQ browser app).
> Create consumer with messageSelector and do consumer.receiveNoWait() always
> receive NULL message.
> Have only three message in queue.
> code sample...
> try
> {
>
> ActiveMQConnectionFactory connectionFactory = new
> ActiveMQConnectionFactory("tcp://localhost:61616");
> Connection connection= connectionFactory.createConnection();
> connection.start();
> Session session=
> connection.createSession(false,Session.AUTO_ACKNOWLEDGE);
> Destination queueDestination = session.createQueue("TestQueue");
> //using activeMq browser app i can see message is there with
> JMSCorrelationID=12345
> String messageSelector= "JMSCorrelationID = '12345'";
> MessageConsumer consumer=
> session.createConsumer(queueDestination,messageSelector);
> Message message= consumer.receiveNoWait();
> if(message==null)
> {
> // always return null message
> //log message not found
> }
>
> }
> catch (Exception e)
> {
> }
> But, if do this it’s works …
> For(int i=0; i< 7; i++)
> {
> Thread.sleep(100);
> message= consumer.receiveNoWait();
> If(message!=null)
> Break;
> }
> please help me what am i doing wrong?
