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

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()));

  }
}

这是实体：

package ejbserviceclient;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class ExCourse {

int id;

}

但也有例外：

看起来你没有JAXBContext正确初始化你的。您需要通知它所有可能@XmlRootElement被解析的类名。

因此你需要改变

JAXBContext context = JAXBContext.newInstance(EjbServiceClient.class)

到

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