[jboss-user] [JBossWS] - Type mapping trouble with JAX-WS and EJB3

[JoPe]

I'm trying to write my first own webservice using EJBs (V3) in a JBoss 4.2.2. Building and deploying the webservice bean works fine, but when I try to access a web method with no parameters and no return type like this:
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
  | {
  |     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();        
  |     }
  | }    
it throws 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:18)    
where the last line refers to "Service service = factory.createService(url, qname);"
 
My questions are:
1. I thought using JAX-WS and Annotations would take care of all the webservice-configuration-XML-SOAP stuff for me. Do I still need to manually specify a type mapping? How? Where?
2. The web method I try to access has neither parameters nor a return value. How can there be any types to map??
 
If you could make me friends with webservices again, they and I would really appreciate it.
