Returning Complex Type

[burakbayramli]

Hi all,

While trying to return a complex type from a Web Service and I am experiencing some problems:

I am on JBoss 4.2.1.GA and jbossws-1.2.1.GA.

My client receives

Exception in thread "main" org.jboss.ws.WSException: Cannot obtain java/xml type mapping for: {http://service.gg.com/}Product
 at org.jboss.ws.metadata.builder.jaxrpc.JAXRPCMetaDataBuilder.processOutputDocElement(JAXRPCMetaDataBuilder.java:778)

 at org.jboss.ws.core.jaxrpc.client.ServiceFactoryImpl.createService(ServiceFactoryImpl.java:128)
 at com.gg.service.Client.main(Client.java:20)

If I comment out the method which returns the complex type, the client code works fine.

Any ideas would be appreciated,

The code is below;

@WebService
@SOAPBinding(parameterStyle=SOAPBinding.ParameterStyle.BARE)
public interface ProductDb extends Remote {

 @WebMethod String getProductTitle(int id);

 @WebMethod Product getProduct();

}

@Stateless
@WebService(endpointInterface="com.gg.service.ProductDb")
@WebContext(contextRoot="/ggServices")
public class ProductDbBean implements ProductDb {

 @PersistenceContext(unitName="GGLocal")
 EntityManager em;

 public String getProductTitle(int id) {
 Product prd = em.find(Product.class, id);
 return prd.getTitle();
 }

 public Product getProduct() {
 List<Product> l = em.createQuery("from Product").getResultList();
 return l.get(0);
 }
}

public class Client
{
 public static void main(String[] args) throws Exception
 {
 URL url = new URL("http://localhost:8080/ggServices/ProductDbBean?wsdl");
 QName qname = new QName("http://service.gg.com/", "ProductDbBeanService");

 ServiceFactory factory = ServiceFactory.newInstance();
 Service service = factory.createService(url, qname);
 ProductDb s = (ProductDb) service.getPort(ProductDb.class);

 String test = s.getProductTitle(1);
 }
}
