Returning lists on jbossws-1.2.1.GA

[burakbayramli]

Hi all,

How can we return lists using @WebMethod, @WebService annotations

I have used the following code but I received the error below:

Exception in thread "main" org.jboss.ws.WSException: Cannot obtain java type mapping for: {http://service.gg.com/}arrayList

Code:

@WebService
@SOAPBinding(style=Style.RPC)
public interface ProductDb extends Remote {

 @WebMethod ArrayList<Product> getProducts();

}

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

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

 public ArrayList<Product> getProducts() {
 List<Product> l = em.createQuery("from Product").getResultList();
 ArrayList<Product> list = new ArrayList<Product>();
 for (Product p : l) {
 list.add(p);
 }
 return list;
 }


}

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);

 ArrayList<Product> list = s.getProducts();

 }

Thanks in advance,
