Ni ninguno de su superclase se conoce en este contexto

Question

Estoy tratando de enviar alguna entidad al servicio web basado en ejb. Aquí está mi Web código de cliente de servicio:

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())); 

    } 
} 

Y aquí es la entidad:

package ejbserviceclient; 

import javax.xml.bind.annotation.XmlRootElement; 

@XmlRootElement 
public class ExCourse { 

int id; 

} 

Pero hay una excepción:

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

Parece que no se ha inicializado el JAXBContext correctamente. Debe informarle de todos los posibles nombres de clase @XmlRootElement que podrían ser analizados.

lo tanto es necesario cambiar

JAXBContext context = JAXBContext.newInstance(EjbServiceClient.class) 

a

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