How to inject EJB with @WebServiceRef from Web-module

I have a JEE6 application, with an ejb and a web-module, running on a GlassFish 3.1.1 Now I wanted to access a WebService (JAX-WS) by injecting it (as a Session Bean) into several Managed Beans.

@Stateless
public class AnyService implements AnyServiceLocal {

    @WebServiceRef(wsdlLocation = "META-INF/wsdl/AnyService/Any.wsdl")
    private AnyService service;
    @Override
    public String findLastname(Integer key) {
        Any port = service.getAnyPort();
        AnyPerson sp = port.findAnynumber(key);
        return sp.getLastname();
    }

}

When I try to access it:

@ManagedBean
@SessionScoped
public class UserBean {

    @EJB
    private AnyServiceLocal any;
    public void findLastname() {
        name = any.findLastname(Integer.valueOf(key));
    }
}

I'll get these Exceptions

    (somewhat shortened..)

But when I access the WS directly from within the UserBean, it works.. Looking forward to your ideas :)

*yay my first post^^

I've got the solution! Transactions with Webservices have to be atomic, like dependency injection. But it tries to nest the request into the injection-transaction (hihi this rhymes), so it's not atomic anymore. You can bypass that for the specific method, with an annotation:

@Stateless
@LocalBean
public class AnyServices{

    @WebServiceRef(wsdlLocation = "META-INF/wsdl/AnyService/Any.wsdl")
    private AnyService service;

    @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
    public String findLastname(Integer key) {
        Any port = service.getAnyPort();
        AnyPerson sp = port.findAnynumber(key);
        return sp.getLastname();
    }

}
