XFire Dynamic Client怎么调用传对象的service方法？

daryl715 2007-07-24 03:02:24

User user=new User("1111","1234");
Client client=new Client(new URL("http://localhost:8080/XFireStudy/services/IHelloWorldService?wsdl"));
Object result[]=client.invoke("HelloWorld", new Object[]{user});
System.out.println(result[0]);

我的HelloWorld接受一个user对象，可这使用出现下列异常

简单类型，比如new Object[]{"123"}的方法就可以，我已经配置了相应的aegis文件，不用dynamic client访问user对象为参数的service方法是没有问题的
