WFLYEJB0094: EJB 3.1 FR 5.4.2 MessageDrivenBean does not implement 1 interface nor specifies message listener interface ------------------------------------------------------------------------------------------------------------------------ Key: WFLY-13152 URL: https://issues.redhat.com/browse/WFLY-13152 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 17.0.1.Final Reporter: Rhuan Rocha Assignee: Cheng Fang Priority: Major Attachments: lib.zip, samplemdbear.zip The MDB does not works when it extends a superclass that comes from an external JAR and this super class implements the MessageListener. It generates this exception: {code:java} WFLYEJB0094: EJB 3.1 FR 5.4.2 MessageDrivenBean com.exemple.MyMDB does not implement 1 interface nor specifies message listener interface {code} These are what I have noted: * It only happens in a EAR project. In a WAR project it works fine. * It only happens when the abstract class come from an external JAR * If the sub class implements directly the MessageListener or if the messageListenerInterface is defined in the annotation it works fine.
