NoSUchMethodException in Message Driven Bean

[thl-mot]

I created a very simple MDB. Like the one in the online documentation (code shown below). After sending a Message to the specified topic I get the following message on the servers console (JBoss 3):

[11:06:57,920,JMSContainerInvoker] Exception in JMSCI message listener

Here the Beans source code (Compiled with Java 1.3.1):

package test.ejb;

import javax.ejb.*;
import javax.jms.*;

public class MessageBean implements MessageDrivenBean, MessageListener {

public MessageBean() {
}

public void setMessageDrivenContext(MessageDrivenContext parm1) throws javax.ejb.EJBException {
}

public void ejbRemove() throws javax.ejb.EJBException {
}

public void onMessage(Message parm1) {
System.out.println( parm1.toString());
}
}

I also have this problem under JBoss-2.4.1_Tomcat-3.2.3 - does anyone have an explanation?

[matt.h]

Okay the issue is that the MDB must implement ejbCreate()... although interestingly this method ISN'T specified in javax.ejb.MessageDrivenBean.

I have solved the problem,
it was defenitely the missing ejbCreate method.

I was getting the same message, and implementing a dummy ejbCreate() did fix the problem. Can anybody on the development team comment as to why an ejbCreate() is required of an MDB when it is in fact not in the MDB spec?

thanks,
Deepak.
