Cannot obtain java type mapping for {http://business/jaws}Li

[jaguaraci]

Hello,

I'm using Jboss 4.0.5G, JbossWS 1.0.3, SDK 1.5.0_9 and Windows XP_SP2.

I have created theses classes using EJB3 annotation:

package business;

import java.rmi.Remote;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

@WebService
@SOAPBinding(style = Style.RPC)
public interface SelecionarMusicas extends Remote{
public java.util.List selecionarMusicas() ;
}

package business;

import java.util.ArrayList;
import java.util.List;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.jws.WebService;

import transfer.MusicaTO;

import delegate.ManterMusicaDelegate;
import exceptions.MusicaException;

@Stateless
@WebService(endpointInterface="business.SelecionarMusicas")
@Remote(SelecionarMusicas.class)
public class SelecionarMusicasWS {

public java.util.List selecionarMusicas() throws MusicaException{

List musicas = new ArrayList();
ManterMusicaDelegate delegate;
delegate = new ManterMusicaDelegate();
musicas = delegate.selecionarMusicas();
return musicas;
}

}


package client;

import java.net.MalformedURLException;
import java.net.URL;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import javax.xml.namespace.QName;
import javax.xml.rpc.ServiceException;
import javax.xml.rpc.ServiceFactory;
import javax.xml.rpc.Service;

import transfer.MusicaTO;
import business.SelecionarMusicas;

public class WebserviceClient {

private static final String nameSpace="http://business/jaws";
private static final String service="SelecionarMusicasService";
private static final String wsdl="http://localhost:8080/easd2007/SelecionarMusicasWS?wsdl";

public static void main(String[] args) {
try {

System.out.println("Starting Test Client");
URL url = new URL(wsdl);
QName qname = new QName(nameSpace,service);
System.out.println("Creating a service");
ServiceFactory factory = ServiceFactory.newInstance();
Service remote = factory.createService(url, qname);
System.out.println("Obtaining reference to a proxy object");
SelecionarMusicas proxy = (SelecionarMusicas) remote.getPort(SelecionarMusicas.class);
System.out.println("Accessed local proxy: " + proxy);
System.out.println("Receiving data: ");

List musicas = new ArrayList();
musicas = proxy.selecionarMusicas();
for (Iterator iter = musicas.iterator() ; iter.hasNext();){
System.out.print("Nome: "+ iter.next().getNome());
System.out.print("Tom: "+ iter.next().getNome());
System.out.print("Dominante Primário: "+ iter.next().getNome());
System.out.print("Dominante Secundário: "+ iter.next().getNome());
System.out.print("Diminuto Ascendente: "+ iter.next().getNome());
System.out.print("Diminuto Descendente: "+ iter.next().getNome());
System.out.print("Diminuto Alternativo: "+ iter.next().getNome());
System.out.print("Clichê Harmônico: "+ iter.next().getNome());
}



} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

catch (ServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}

When I try to use a webservice client happens it:

Exception in thread "main" org.jboss.ws.WSException: Cannot obtain java type mapping for: {http://business/jaws}List

Somebody know why ?

Thanks!

Hi,

I have been working several days with this issue. At last this problem is caused in the Client application. In my case a web app. It was not able to recognize the type that the server was returning (ArrayList in this case).

Another important thing, correct me if I am wrong, is that Web Services Soap Messages not support ArrayList directly, so if you would like to use it you must implement an ArrayList by yourself. A pretty hard work. The thing that I have done is to return an Array (suported by the Web Services) of my own objects, that I have mapped previously.

My solution was to create a Web Service Client using Eclipse Wtp. It creates a EAR that includes all the necessary stuff for map the user types.

What's this type mapping about after all? I'm trying to write my first own webservice and did two tutorials, leading to this client code:

package test.de.laliluna.library;

import java.net.URL;

import javax.xml.namespace.QName;
import javax.xml.rpc.Service;
import javax.xml.rpc.ServiceFactory;

import de.laliluna.library.BookTestBean;

public class WebServiceTestClient
{

 /**
 * @param args
 */
 public static void main(String[] args) throws Exception
 {
 URL url = new URL("http://localhost:8080/FirstEjb3Tutorial/BookTestBean?wsdl");
 QName qname = new QName("http://library.laliluna.de/", "BookTestBeanService");
 ServiceFactory factory = ServiceFactory.newInstance();
 Service service = factory.createService(url, qname);

 BookTestBean serviceEndpoint = (BookTestBean)service.getPort(BookTestBean.class);

 serviceEndpoint.test();
 }
}

leading to this exception:

Exception in thread "main" org.jboss.ws.WSException: Cannot obtain java type mapping for: {http://library.laliluna.de/}test
 at org.jboss.ws.metadata.builder.jaxrpc.JAXRPCMetaDataBuilder.processDocElement(JAXRPCMetaDataBuilder.java:627)
...
 at test.de.laliluna.library.WebServiceTestClient.main(WebServiceTestClient.java:22)

The last line refers to the statement "Service service = factory.createService(url, qname);"


I expected not to have to care about XML internals of the web service when using Java Annotations - like this:

@WebMethod
 @Oneway
 public void test()
 {...

So, if you could answer these questions:
1. Where/how can I manually specify a type mapping? Or do I need to extend my Annotations?
2. My web method has neither parameters nor a return value, how can there be any types to map??

I'd really appreciate it.

Also, does anybody know a good webservices tutorial for complete webservice rookies using JBoss?

Thanks in advance!
