Mediation problem with WAS 6.1

Question

I'm working with SIBus in WAS 6.1 Problem is that medations won't execute when sending messages to destinations. I get this error:
The handler list MyMediation contains a handler MyMediation, which does not implement the MediationHandler interface
public class MyMediation implements MediationHandler {
     public boolean handle(MessageContext arg0) throws MessageContextException {
          System.out.println("***********************");
          System.out.println("********MEDIATE********");
          System.out.println("***********************");
                                     //Some other stuff...
          return true;
}I don't know what I have done wrong. This is a simple java class in EJB project. Here is the ejb-jar.xml
<ejb-jar id="ejb-jar_ID" version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">
