Hi there, I am having a problem with inheritance, aop and message driven beans (using JBoss 4.0.4 GA with the EJB 3 option enabled).
I defined a couple of MDBs which listen to some topics and do nothing than log a little hello in the first instance. So my code looks something like: | @MessageDriven( | description="My Message driven bean to test JMS implementation. It does nothing but loggin the log4j.", | name="LogOneMDB", | activationConfig={ | @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic") | ,@ActivationConfigProperty(propertyName = "destination", propertyValue = "topic/one") | ,@ActivationConfigProperty(propertyName="Durability",propertyValue="Durable")//subscription | ,@ActivationConfigProperty(propertyName="subscriptionName",propertyValue = "LogOneMDB") | ,@ActivationConfigProperty(propertyName="clientID",propertyValue = "LogOneMDB") | } | ) | public class LogOneMDB extends AbstractMDB implements MessageListener{} | | @MessageDriven( | description="My Message driven bean to test JMS implementation. It does nothing but loggin the log4j.", | name="LogTwoMDB", | activationConfig={ | @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic") | ,@ActivationConfigProperty(propertyName = "destination", propertyValue = "topic/two") | ,@ActivationConfigProperty(propertyName="Durability",propertyValue="Durable")//subscription | ,@ActivationConfigProperty(propertyName="subscriptionName",propertyValue = "LogTwoMDB") | ,@ActivationConfigProperty(propertyName="clientID",propertyValue = "LogTwoMDB") | } | ) | public class LogTwoMDB extends AbstractMDB implements MessageListener{} | and a (abstract) super class implementing the listener method: | class AbstractMDB { | public void onMessage(final Message message) { | Logger.getLogger(this.getClass()).debug("Received a message."); | } | } | If you deploy something like this and send a message to the topic(s) you end up with following exception: | 3459235 [ERROR][JMS SessionPool Worker-58][org.jboss.ejb3.mdb.MDB] Exception in JMSCI message listener | java.lang.IllegalAccessException: Class org.jboss.aop.joinpoint.MethodInvocation can not access a member of class com.your.package.AbstractMDB with modifiers "public" | at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:65) | at java.lang.reflect.Method.invoke(Method.java:578) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:112) | at org.jboss.ejb3.interceptor.InvocationContextImpl.proceed(InvocationContextImpl.java:166) | at org.jboss.ejb3.interceptor.EJB3InterceptorsInterceptor.invoke(EJB3InterceptorsInterceptor.java:63) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.entity.TransactionScopedEntityManagerInterceptor.invoke(TransactionScopedEntityManagerInterceptor.java:54) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.AllowedOperationsInterceptor.invoke(AllowedOperationsInterceptor.java:47) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.aspects.tx.TxPolicy.invokeInCallerTx(TxPolicy.java:126) | at org.jboss.aspects.tx.TxInterceptor$Required.invoke(TxInterceptor.java:201) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.stateless.StatelessInstanceInterceptor.invoke(StatelessInstanceInterceptor.java:62) | at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) | at org.jboss.ejb3.mdb.MDB.localInvoke(MDB.java:865) | at org.jboss.ejb3.mdb.MDB.localInvoke(MDB.java:844) | at org.jboss.ejb3.mdb.MDB$MessageListenerImpl.onMessage(MDB.java:1074) | at org.jboss.jms.asf.StdServerSession.onMessage(StdServerSession.java:266) | at org.jboss.mq.SpyMessageConsumer.sessionConsumerProcessMessage(SpyMessageConsumer.java:902) | at org.jboss.mq.SpyMessageConsumer.addMessage(SpyMessageConsumer.java:170) | at org.jboss.mq.SpySession.run(SpySession.java:323) | at org.jboss.jms.asf.StdServerSession.run(StdServerSession.java:194) | at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(PooledExecutor.java:748) | at java.lang.Thread.run(Thread.java:595) | Am I overseeing something or is this a bug of the EJB3 MDB implementation?
