Aucune de ses super classes n'est connue dans ce contexte

J'essaie d'envoyer une entité au service Web basé sur ejb. Voici mon code client de service Web:

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()));

  }
}

Et voici l'entité:

package ejbserviceclient;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class ExCourse {

int id;

}

Mais il y a une exception:

Exception in thread "main" javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException

Il semble que vous n'ayez pas correctement initialisé votre JAXBContext. Vous devez l'informer de tous les possibles @XmlRootElement noms de classe qui pourraient être analysés.

Vous devez donc changer

JAXBContext context = JAXBContext.newInstance(EjbServiceClient.class)

à

JAXBContext context = JAXBContext.newInstance(ejbserviceclient.ExCourse.class)
