[jboss-user] [JBossWS] - 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.metadata.builder.jaxrpc.JAXRPCMetaDataBuilder.buildParameterMetaDataDoc(JAXRPCMetaDataBuilder.java:897)
  | 	at org.jboss.ws.metadata.builder.jaxrpc.JAXRPCMetaDataBuilder.setupOperationsFromWSDL(JAXRPCMetaDataBuilder.java:214)

  | 	at org.jboss.ws.metadata.builder.jaxrpc.JAXRPCClientMetaDataBuilder.buildMetaData(JAXRPCClientMetaDataBuilder.java:133)
  | 	at org.jboss.ws.metadata.builder.jaxrpc.JAXRPCClientMetaDataBuilder.buildMetaData(JAXRPCClientMetaDataBuilder.java:85)
  | 	at org.jboss.ws.core.jaxrpc.client.ServiceImpl.<init>(ServiceImpl.java:111)
  | 	at org.jboss.ws.core.jaxrpc.client.ServiceFactoryImpl.createService(ServiceFactoryImpl.java:157)
  | 	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);
  |   }
  | }
  |
