I get this error: No endpoint mapping found for [SaajSoapMessage {http://mycompany/coolservice/specs}ChangePerson]

Following is my ws config file:

<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping">
    <description>An endpoint mapping strategy that looks for @Endpoint and @PayloadRoot annotations.</description>
</bean>

    </list>
    </property>
     <property name="inline" value="true"/>      
</bean>

I have then the following files:

public interface MarshallingPersonService {

public final static String NAMESPACE = "http://mycompany/coolservice/specs";
public final static String CHANGE_PERSON = "ChangePerson";

public RespondPersonType changeEquipment(ChangePersonType request);
}

and

  @Endpoint
  public class PersonEndPoint implements MarshallingPersonService {

    @PayloadRoot(localPart=CHANGE_PERSON, namespace=NAMESPACE)
    public RespondPersonType changePerson(ChangePersonType request) {
        System.out.println("Received a request, is request null? " + (request == null ? "yes" : "no"));
        return null;        
    }

}

I am pretty much new to WebServices, and not very comfortable with annotations. I am following a tutorial on setting up jaxb marshaller in springws. I would rather use xml mappings than annotations, although for now I am getting the error message.
