The request/reply messaging pattern is useful for your requirement. You typically use a CorrelationId to relate request & reply messages.

While sending request message you set JMSReplyTo destination on the message. Typically a temporary queue is used as JMSReplyTo destination. When creating a consumer to receive response use a selector with JMSCorrelationId, something like

cons = session.createConsumer(tempDestination,"JMSCorrelationId="+requestMsg.JMSMessageId);

At the other end, the application that is processing the request message must use the JMSReplyTo destination to send response. It must also use the MessageId of the request message and set it as CorrelationId of the response message.
