J2EE WebService und .net Client - seltsame Datentypen

Ich hab mir ein EJB3-Minimal-WebService gebaut, wo ich eine Methode ohne Parameter habe:

Code:

---

package example;

import javax.ejb.*;
import javax.jws.*;
import javax.jws.soap.*;

@WebService
@SOAPBinding( style = SOAPBinding.Style.DOCUMENT )
@Stateless
@Remote( IRandom.class )
public class Random {

        @WebMethod
        public boolean getRandom() {
                if ( Math.random() < 0.5 ) {
                        return false;
                } else {
                        return true;
                }
        }
}

---

Dann wird das ganze mit der folgenden web.xml deployed:

Code:

---

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation = "http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
        <servlet>
                <servlet-name>Random</servlet-name>
                <servlet-class>example.Random</servlet-class>
        </servlet>
        <servlet-mapping>
                <servlet-name>Random</servlet-name>
                <url-pattern>/Random</url-pattern>
        </servlet-mapping>
</web-app>

---

Sodass mir der JBoss die folgende WSDL zur Verfügung stellt:

Code:

---

<definitions name='RandomService' targetNamespace='http://example/jaws' xmlns='http://schemas.xmlsoap.org/wsdl/' xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/' xmlns:tns='http://example/jaws' xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
 <types>
  <schema elementFormDefault='qualified' targetNamespace='http://example/jaws' xmlns='http://www.w3.org/2001/XMLSchema' xmlns:soap11-enc='http://schemas.xmlsoap.org/soap/encoding/' xmlns:tns='http://example/jaws' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
  <complexType name='getRandom'>
    <sequence/>
  </complexType>
  <complexType name='getRandomResponse'>
    <sequence>
    <element name='result' type='boolean'/>

    </sequence>
  </complexType>
  <element name='getRandom' type='tns:getRandom'/>
  <element name='getRandomResponse' type='tns:getRandomResponse'/>
  </schema>
 </types>
 <message name='Random_getRandom'>
  <part element='tns:getRandom' name='parameters'/>
 </message>

 <message name='Random_getRandomResponse'>
  <part element='tns:getRandomResponse' name='result'/>
 </message>
 <portType name='Random'>
  <operation name='getRandom'>
  <input message='tns:Random_getRandom'/>
  <output message='tns:Random_getRandomResponse'/>
  </operation>
 </portType>

 <binding name='RandomBinding' type='tns:Random'>
  <soap:binding style='document' transport='http://schemas.xmlsoap.org/soap/http'/>
  <operation name='getRandom'>
  <soap:operation soapAction=''/>
  <input>
    <soap:body use='literal'/>
  </input>
  <output>
    <soap:body use='literal'/>

  </output>
  </operation>
 </binding>
 <service name='RandomService'>
  <port binding='tns:RandomBinding' name='RandomPort'>
  <soap:address location='http://itwien2:8080/random/Random'/>
  </port>
 </service>
</definitions>

Wenn ich jetzt in Visual Studio (2005 c# express) eine WebReferenz auf das ganze einfüge, kann ich zwar prinzipiell wunderbar damit arbeiten, jedoch will das etwas unlogische Datentypen haben:

Code:

---

getRandom ( getRandom As getRandom ) As getRandomResponse

---

Wenn ich die WebReferenz darauf z.B. JBossApplication nenne, dann benötige ich den folgenden Code um darauf zuzugreifen:

Code:

---

using System;
using System.Collections.Generic;
using System.Text;

namespace RandomTest
{
    class Program
    {
        static void Main(string[] args)
        {
            JBossApplication.RandomService service = new JBossApplication.RandomService();
            JBossApplication.getRandomResponse response;
            response = service.getRandom( new JBossApplication.getRandom() );
            System.Console.WriteLine(response.result);

            System.Console.WriteLine();
        }
    }
}

---

Wenn ich ein service.getRandom( null ) mache, bekomme ich im JBoss eine NoSuchElementException:

Code:

---

Woran liegt das? Warum muss ich als Parameter und Rückgabe so seltsame Datentypen machen, und nicht so wie es definiert ist? Wenn ich das WebService aus einem Java-Client ansprechen will, verhält es sich wie erwartet, nur in .net ist es etwas seltsam.
