Hello,
I have an java EE application which has one message-driven bean and it runs fine on JBoss 4, however when I configure the project for JBoss 6 and deploy on it, I get this error;
WARN [org.jboss.ejb.deployers.EjbDeployer.verifier] EJB spec violation:
...
The message driven bean must declare one onMessage() method.
...
org.jboss.deployers.spi.DeploymentException: Verification of Enterprise Beans failed, see above for error messages.
But my bean HAS the onMessage method! It would not have worked on jboss 4 either then.
Why do I get this error!?
Edit:
The class in question looks like this
package ...
imports ...
public class MyMDB implements MessageDrivenBean, MessageListener {
AnotherSessionBean a;
OneMoreSessionBean b;
public MyMDB() {}
public void onMessage(Message message) {
if (message instanceof TextMessage) {
try {
//Lookup sessionBeans by jndi, create them
lookupABean();
// check message-type, then invokie
a.handle(message);
// else
b.handle(message);
} catch (SomeException e) {
//handling it
}
}
}
public void lookupABean() {
try {
// code to lookup session beans and create.
} catch (CreateException e) { // handling it and catching NamingException too }
}
}
Edit 2: And this is the jboss.xml relevant parts
<message-driven>
<ejb-name>MyMDB</ejb-name>
<destination-jndi-name>topic/A_Topic</destination-jndi-name>
<local-jndi-name>A_Topic</local-jndi-name>
<mdb-user>user</mdb-user>
<mdb-passwd>pass</mdb-passwd>
<mdb-client-id>MyMessageBean</mdb-client-id>
<mdb-subscription-id>subid</mdb-subscription-id>
<resource-ref>
<res-ref-name>jms/TopicFactory</res-ref-name>
<jndi-name>jms/TopicFactory</jndi-name>
</resource-ref>
</message-driven>
