Hi, Thank you very much. But I still can not get through. Please look at what I did and let me know if you have any idea. I am using JBoss5.0.0CR2. The configuration file I think is this one: C:\jboss-5.0.0.CR2\server\default\deploy\messaging\destinations-service.xml. I added a new based the code you give me (with some modificaitons -- Change the Topic to Queue and the jia.jms to jboss.messaging.destination). I don't understand the yet but I assume it is not related to our problem. I can not remove the @Resource(mappedName="jms/NewMessageFactory") private ConnectionFactory connectionFactory; Since it will prevent me to compile the servlet on this line: Connection connection = connectionFactory.createConnection(); Here is the modified configuration file: <?xml version="1.0" encoding="UTF-8"?> | | <!-- | Messaging Destinations deployment descriptor. | | $Id: destinations-service.xml 72251 2008-04-16 00:38:50Z clebert.suconic(a)jboss.com $ | --> | | <server> | | <!-- | The Default Dead Letter Queue.
