Type mapping trouble with JAX-WS and EJB3

[Johannes Koch]

I'm trying to write my first own webservice using EJBs (V3) in a JBoss as server. 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.

        em.remove(book2);
        System.out.println("List all books");
        allBooks = em.createQuery("from Book").getResultList();
        for(Iterator iter = allBooks.iterator(); iter.hasNext()   :wink:   
        {
            Book element = (Book)iter.next();
            System.out.println(element);
        }
    }
}
