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
网友回复:我知道webservice包括corba一般只支持基本数据类型,楼主可以将对象转换成List或者数组传递过去
