Hi, I am currently trying to deploy a very simple Message Driven Bean (MDB) in Orion 1.4.5. The MDB is subscribing to a topic. To do this I have studied the atm application and the logging MDB used there. Orion deploy's my MDB without any error messages but the bean is not responding when a message is published on the topic. To me it seems like the MDB doesn't know or understand what topic it should subscribe to. I use a client to publish a message on the topic. If I start another client subscribing to the same topic, everything works fine. The jms.xml file seems to be ok. I think I am missing something connecting the MBD with the topic in the ejb-jar.xml file. When I created my ejb-jar.xml file I copied the relevant parts from the atm ejb-jar.xml file. I have studied other MDB examples and tried to modify my ejb-jar.xml file according to those examples but so far nothing has worked. My MDB is the src.java.ejb.NewOrderBean and the topic name is orderTopic. This is my ejb-jar.xml file: <ejb-jar> <enterprise-beans> <message-driven> <ejb-name>src.java.ejb.NewOrderBean</ejb-name> <ejb-class>src.java.ejb.NewOrderBean</ejb-class> <message-selector>JMSType='orderTopic'</message-selector> <message-driven-destination> <destination-type>javax.jms.Topic</destination-type> </message-driven-destination> </message-driven> </enterprise-beans> </ejb-jar> My hopes are that someone could help in this matter.
