EJB3 & Web Services

Question

Hello everybody. I've been working with JEE using Eclipse and JBoss. Right now i have an "shopping cart application" which uses entity and session beans (stateless ant statefull). I'm using JSF technology for the web deployment. Everything works fine. Now, I want to add web services to the application. I've already packed a Stateless bean which exposes a web service fucntionality. Here it is:
@Stateless()
@WebService()
public class CarritoWS implements ILocalCarritoWS, IRemotaCarritoWS
    @EJB(name = "uniandes.cupi2.aplicacionIntermediaria.services.IServiciosProductos")
    private IServiciosProductos serviciosProducto;
    @WebMethod
    public String getCategoriesProducts(@WebParam String categories)
        String response = "";
        try
            response = serviciosProducto.findByCategory(categories).toString();
        catch (PersistenciaException e)
            e.printStackTrace();
        return response;
    }Well, here is the client:
String endpointURL = "http://localhost:8080/intermediario/CarritoWS?wsdl";
        String targetNS = "http://webservices.aplicacionIntermediaria.cupi2.uniandes/jaws";
        URL wsdlURL = new URL(endpointURL);
        QName serviceName = new QName(targetNS, "ICarritoWSService");
        Service service = Service.create(wsdlURL, serviceName);
        ICarritoWS carrito = (ICarritoWS) service.getPort(ICarritoWS.class);
        String response = carrito.getCategoriesProducts("deportivo");
        System.out.println(response);The wsdl file generated exposes everything OK, but I got an exception when accesing the webservice:
Exception in thread "main" javax.xml.ws.WebServiceException:

Hi
You seem to be mixing JWSDP and JBossWS libs in the client classpath. Try removing the JWSDP libraries and solely rely on the JBOSS_HOME/client/*.jar libraries. You may also take a look at the jbossws samples that ship with the distribution.
