我正在尝试将一些实体发送到基于ejb的Web服务.这是我的Web服务客户端代码：

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()));

}

}

这里是实体：

package ejbserviceclient;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement

public class ExCourse {

int id;

}

但有例外：

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