As there seems to be a basic incompatibility with version 4.2.0 connecting to a message queue hosted on legacy version 3.0.3 (issue posted on the JNDI board), I thought I'd just move the legacy app containing the message bean to version 4.2.0. In theory I should just be able to take the .jar file containing the message bean and deploy it. No special configuration required as the legacy app uses "queue/testQueue". After fixing an ejb-jar.xml issue that 3.0.3 didn't have a problem with, I now get this error on 4.2.0: 13:57:43,375 WARN [verifier] EJB spec violation: | Bean : AutoCreditMessageBean | Section: 15.7.2 | Warning: A message driven bean must implement, directly or indirectly, the message listener class But it does: public class AutoCreditMessageBean implements javax.ejb.MessageDrivenBean, javax.jms.MessageListener | { | ... | } And the deployment descriptor specifies it. ejb-jar.xml: <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd"> | | <ejb-jar> | <enterprise-beans> | <message-driven> | | <ejb-name>AutoCreditMessageBean</ejb-name> | <ejb-class>org.myorg.AutoCreditMessageBean</ejb-class> | | <transaction-type>Container</transaction-type> | <message-selector>messageType = 'request'</message-selector> | <messaging-type>javax.jms.MessageListener</messaging-type> | | <acknowledge-mode>Auto-acknowledge</acknowledge-mode> | | <message-driven-destination> | <destination-type>javax.jms.Queue</destination-type> | </message-driven-destination> | | </message-driven> | | </enterprise-beans> | | <assembly-descriptor> | </assembly-descriptor> | | </ejb-jar> jboss.xml: <?xml version="1.0" encoding="UTF-8"?> | | <jboss> | | <secure>false</secure> | | <container-configurations /> | | <resource-managers /> | | <enterprise-beans> | | <message-driven> | <ejb-name>AutoCreditMessageBean</ejb-name> | <destination-jndi-name>queue/testQueue</destination-jndi-name> | </message-driven> | | </enterprise-beans> | </jboss> Any thoughts? Or do I have to rewrite this to EJB3? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4146620#...
