Né alcuno della sua super classe è noto a questo contesto

Question

Sto provando a inviare qualche entità al servizio web basato su ejb. Qui è il mio web il codice client del servizio:

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())); 

    } 
} 

E qui è un'entità:

package ejbserviceclient; 

import javax.xml.bind.annotation.XmlRootElement; 

@XmlRootElement 
public class ExCourse { 

int id; 

} 

Ma c'è un'eccezione:

Answer 1

Sembra che tu non hai inizializzato il JAXBContext correttamente. È necessario informarlo di tutti i possibili nomi di classe @XmlRootElement che potrebbero essere analizzati.

quindi è necessario cambiare

JAXBContext context = JAXBContext.newInstance(EjbServiceClient.class) 

a

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