Subject RE: How to post message to a certain queue consumer?
Date Wed, 19 May 2010 08:22:56 GMT
Session session = ...;
MessageProducer producer = session.createProducer(destination);

producer.setTimeToLive(timeToLiveInMilliseconds); //use the producer API to set TTL

Message message = session.create...Message(...);

producer.send(message);

TTL has nothing to do with message selectors; I found it useful though.

Yes,it works well.
But I work with Visual C#,the method is a little different from yours.
Can you give me some guide about TTL you mentioned in early reply?
