Hi all,

Can anybody tell me whats the use of sending a message to the destination in this way ?

TextMessage request = qSession.createTextMessage();
request.setJMSReplyTo(myQueue);

Thanks in advance,
parineeta

When the application which posts a message expects a response to the message, it sometimes creates a temporary queue and sets this temporary queue in the replyTo property.

Clients which receive the message can post back to this temporary queue with a response. Often the jms correlation id is used to link the two - the request and response messages.

Hi ram,
Thanks for your reply.
Actually i understood its purpose but i am confused in creating temperory queues.
As per my understanding the temperory queues are created dynamically and is used within the same connection and once the connection is closed the temperory queues are deleted.

So in this case how is it possible for another application to connect with this temperory queue and send the reply?

Can you please clear this doubt for me?

thanks in advance.

That's so but you should know that Connections are usually cached and not created every time a new message needs to be sent. Usage of temporary destinations for request-response in jms is standard architecture practise in enterprise systems. It has its advantages and disadvantages. Here is an excellent article explaining it's usage.
