I haven't completed read that tutorial - you could have posted the appropriate code here :-) But here's the code which i think is responsible for the exception: public class PostMessage extends HttpServlet { | @Resource(mappedName="jms/NewMessageFactory") | private ConnectionFactory connectionFactory; | | @Resource(mappedName="jms/NewMessage") | private Queue queue; 1) As far as i know, the connection factory in JBoss is by default bound at "ConnectionFactory". So the first injection should look like: @Resource(mappedName="ConnectionFactory") | private ConnectionFactory connectionFactory; | or even @Resource | private ConnectionFactory connectionFactory; | 2) For the injection of the "queue" to happen, you should have deployed the queue through configuration file to be bound at jms/NewMessage. Have you done that? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186899#...
