title: Nor any of its super class is known to this context
body: <p>I'm trying to send some entity to ejb based web service. Here is my web service client code:</p>
  
  <pre><code>package ejbserviceclient;
  
  import java.net.MalformedURLException;
  import java.net.URL;
  import javax.xml.bind.JAXBContext;
  import javax.xml.bind.JAXBException;
  import javax.xml.namespace.QName;
  import javax.xml.ws.Service;
  
  public class EjbServiceClient {
  
    public static void main(String[] args) throws MalformedURLException, JAXBException {
  
      JAXBContext context = JAXBContext.newInstance(EjbServiceClient.class);
  
  
      URL url = new URL("http://ipsedin:8080/WebServiceBeanService/WebServiceBean?wsdl");
      QName serviceName = new QName(
              "http://ejb.rpt.softcomputer.com/",
              "WebServiceBeanService");
      QName portName = new QName(
              "http://ejb.rpt.softcomputer.com/",
              "WebServiceBeanPort");
  
      Service service = Service.create(url, serviceName);
      Echo ejbService = service.getPort(portName, Echo.class);
  
      System.out.println(ejbService.echo("lololo"));
      System.out.println(ejbService.processExCourse(new ExCourse()));
  
    }
  }
  </code></pre>
  
  <p>And here is entity:</p>
  
  <pre><code>package ejbserviceclient;
  
  import javax.xml.bind.annotation.XmlRootElement;
  
  @XmlRootElement
  public class ExCourse {
  
  int id;
  
  }
  </code></pre>
  
  <p>But there is exception:</p>
  
  <pre><code>Exception in thread "main" javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException
