Annotated WebService problem

[avlevy2k]

Hi,

I'm trying to deploy the following simple web service:

@WebService(name = "EndpointInterface",
targetNamespace = "http://localhost",
serviceName = "HelloService")
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE,
style = SOAPBinding.Style.DOCUMENT)
@Remote({HelloService.class})
@Stateless
public class HelloServiceEJB implements HelloService {

private String hello = "Hello World";

@WebMethod
public String sayHello() {
return hello;
}

@WebMethod
public void setHello(Stringtype hello1) {
this.hello = hello1.value;
}
}

Stringtype is a simple String wrapper class.

when I try to deploy this on JBoss 4.0.4RC2 I get a null pointer exception. Any idea why?

When I change the parameterStyle from BARE to WRAPPED I'm able to deploy it, but then, when I try to generate a client using Visual Studio 2005, it doesn't recognizes the parametes correctly.

Thanks a lot for any help.

Can you supply the stacktrace?

It is illegal for a bare service to have a void return value and the method not be tagged with @Oneway. However, it should be throwing a propper exception telling you this.
