Thanks. I tried adding all these attributes, i get the error : "javax.naming.NameNotFoundException: TestMdbTopic not bound" | @MessageDriven(mappedName = "topic/TestMdbTopic", | activationConfig = { | @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), | @ActivationConfigProperty(propertyName="subscriptionDurability", propertyValue="Durable"), | @ActivationConfigProperty(propertyName="subscriptionName", propertyValue="topicmdb"), | @ActivationConfigProperty(propertyName="clientId", propertyValue="mdbtopic-test"), | @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"), | @ActivationConfigProperty(propertyName = "destination", propertyValue = "topic/TestMdbTopic") | }) | Someone claims it works (in Spanish): http://blog.neodoo.es/fsolans/entry/mdb_con_anotaciones_pojo_ejb3 It does not ( i kept only the attributes he used : mappedName, acknowledgeMode, destinationType, destination) Does anyone else have a clue ?
