Using muse with metro project (jax-ws)

[Alejandro Escalante Medina]

Hello and thanks for your very fine framework. I am trying to implement
WS-Notification support for my application using Muse and jax-ws from the
Metro project.

Is there anyone here that has any experience with this?

I just put together a WS-Notification consumer class using the examples
provided by the muse package, but haven't been able to expose this as a web
service. Take a look at this class:

public class WsNotificationService extends AbstractCapability implements
ConsumerCapability,
      NotificationMessageListener {

    private static final Log log =
LogFactory.getLog(WsNotificationService.class);

    public void initializeCompleted() throws SoapFault {
        super.initializeCompleted();

        NotificationConsumer wsn = (NotificationConsumer)
getResource().getCapability(WsnConstants.CONSUMER_URI);
        wsn.addMessageListener(this);

        log.debug("nitialized!!!");
    }

    public boolean accepts(NotificationMessage message) {
        return true;
    }

    public void process(NotificationMessage message) {
        log.debug("Received message:\n\n" + message);
    }

}

Now, using the @WebService annotation for web services provided by the
jax-ws framework produces a lot of errorrs, since JAXB (used internally by
jax-ws) can't handle a lot of the classes involved in this implementation:

Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 5 counts
of IllegalAnnotationExceptions
org.apache.muse.ws.notification.NotificationMessage is an interface, and
JAXB can't handle interfaces.
    this problem is related to the following location:
        at org.apache.muse.ws.notification.NotificationMessage
        at public org.apache.muse.ws.notification.NotificationMessage
com.jackbe.presto.ec.ws.jaxws.Accepts.arg0
        at com.jackbe.presto.ec.ws.jaxws.Accepts
org.apache.muse.ws.notification.NotificationMessage does not have a no-arg
default constructor.
    this problem is related to the following location:
        at org.apache.muse.ws.notification.NotificationMessage
        at public org.apache.muse.ws.notification.NotificationMessage
com.jackbe.presto.ec.ws.jaxws.Accepts.arg0
        at com.jackbe.presto.ec.ws.jaxws.Accepts
org.apache.muse.ws.addressing.EndpointReference does not have a no-arg
default constructor.
    this problem is related to the following location:
        at org.apache.muse.ws.addressing.EndpointReference
        at public abstract org.apache.muse.ws.addressing.EndpointReference
org.apache.muse.ws.notification.NotificationMessage.getProducerReference()
        at org.apache.muse.ws.notification.NotificationMessage
        at public org.apache.muse.ws.notification.NotificationMessage
com.jackbe.presto.ec.ws.jaxws.Accepts.arg0
        at com.jackbe.presto.ec.ws.jaxws.Accepts
org.w3c.dom.Element is an interface, and JAXB can't handle interfaces.
    this problem is related to the following location:
        at org.w3c.dom.Element
        at public org.w3c.dom.Element
com.jackbe.presto.ec.ws.jaxws.SoapFaultBean.detail
        at com.jackbe.presto.ec.ws.jaxws.SoapFaultBean
org.w3c.dom.Element does not have a no-arg default constructor.
    this problem is related to the following location:
        at org.w3c.dom.Element
        at public org.w3c.dom.Element
com.jackbe.presto.ec.ws.jaxws.SoapFaultBean.detail
        at com.jackbe.presto.ec.ws.jaxws.SoapFaultBean

Of course this a quick shot at the problem and I might be totally missing
the target, that's why I am asking here.

If anyone has any experience or can provide any pointer, I will greatly
appreciate it.

Thanks in advance,

I'm not sure how jax-ws helps with this, but that may be my lack of
experience with it.

The above class looks good.

Muse provides its own internal structure for marshalling and
unmarshalling of xml, the only thing it needs is integeration with a
servlet of some kind.  Perhaps appropriate for your case (using metro)
is to use the soap mini Muse environment (a simple servlet) and
register it in the same web.xml as metro.

I am going to check into this (the mini stuff) to see what I can do. I will
come with more info.
