Ok, I now have my tiny jms client submitting messages, but the ejb doesn't consume them. I use the atm example as guideline and have this running. However when I have a look at the atm example, I notice that neither does atm logs !!1 That is, there doesn't appear anything in the table com_acme_atm_ejb_mainlog table, whereas other tables are filled!! What are the specific orion requirements, such that the jms-ejb consumes the message ?? ( I am running on 1.4.7) and how can I debug the problem (look at the topics's or somthing like that )?? I don't get any output from orion in any log !! (strange!!!) I will shortly explain my client and ejb hereunder as they are really short: The ejb-jar.xml: -------- <ejb-jar> <enterprise-beans> <message-driven> <description>JMS logger</description> <ejb-name>Hello</ejb-name> <ejb-class>HelloMSGBean.HelloBean</ejb-class> <transaction-type>Container</transaction-type> <message-selector>JMSType='mainLogMessage'</message-selector> <message-driven-destination> <destination-type>javax.jms.Topic</destination-type> </message-driven-destination> </message-driven> </enterprise-beans> </ejb-jar> -------- The onmessage part in the ejb: ------------ public void onMessage(Message message) { System.out.println("onMessage"); TextMessage textmessage = null; if (message instanceof TextMessage) { textmessage = (TextMessage)message; } else { return; } ---------- The client part: --------------- ctx=new InitialContext(p); tcf=(TopicConnectionFactory)ctx.lookup("java:comp/env/jms/theTopicConnection Factory"); tcon = tcf.createTopicConnection(); tcon.start(); tsession = tcon.createTopicSession(false, Session.AUTO_ACKNOWLEDGE); topic = (Topic)ctx.lookup("java:comp/env/jms/theTopic"); tpublisher = tsession.createPublisher(topic); TextMessage message = tsession.createTextMessage(); message.setJMSType("mainLogMessage"); message.setText("Hello, World"); tpublisher.publish(message); ---------------- The part in the jms.xml file (I am not sure if this is necessary!!!??): ------------- <topic name="Demo Topic" location="jms/theTopic"> <description>A dummy topic</description> </topic> -------------- The application-client.xml: ----------------- <application-client> <display-name>Something</display-name> <resource-ref> <res-ref-name>jms/theTopicConnectionFactory</res-ref-name> <res-type>javax.jms.TopicConnectionFactory</res-type> <res-auth>Container</res-auth> </resource-ref> <resource-ref> <res-ref-name>jms/theTopic</res-ref-name> <res-type>javax.jms.Topic</res-type> <res-auth>Container</res-auth> </resource-ref> </application-client> ---------------- That's it, but the ejb doesn't print anything to the STDOUT. What am I doing wrong ????. Eddie
