如何从java调用Web服务(由wsdl描述)

import org.apache.cxf.frontend.ClientProxyFactoryBean;
import com.example.webservice.MyWebService;

public class MyWebServiceClient {
    public static void main(String[] args) {
        ClientProxyFactoryBean factory = new ClientProxyFactoryBean();
        factory.setServiceClass(MyWebService.class);
        factory.setWsdlLocation("http://example.com/mywebservice?wsdl");
        MyWebService service = (MyWebService) factory.create();
        String result = service.myMethod("hello");
        System.out.println(result);
    }
}
