在学习webservice的时候，经常将ns和url花了好久时间才理解过来，这里备份下！

首先定义接口：

@WebService  
public interface IService  
\{  
@WebResult(name = "login")  
public User login(@WebParam(name = "username") String username,  
@WebParam(name = "password") String password);  
\}

创建实现类：

@WebService(endpointInterface = "com.cml.soap.IService\[这里是实现接口的全路径\]", name = "myname")  
public class ServiceImpl implements IService  
\{  
@Override  
@WebResult(name = "login")  
public User login(@WebParam(name = "username") String username,  
@WebParam(name = "password") String password)  
\{  
System.out.println("进来登录");  
return new User("恭喜你登录成功！", 1);  
\}  
\}

发布服务：

String address = "http://localhost:8888/cml";  
Endpoint.publish(address, new ServiceImpl());

在浏览器上输入http://localhost:8888/cm?wsdl

创建soap消息：

public void sendSoap() throws Exception  
\{  
String ns = "http://soap.cml.com/";  
QName name = new QName(ns, "ServiceImplService");  
  
String url = "http://localhost:8888/cml?wsdl";  
// 使用的是url进行服务的创建  
Service service = Service.create(new URL(url), name);  
  
  
Dispatch<SOAPMessage> dispatch = service.createDispatch(new QName(ns,  
"mynamePort"), SOAPMessage.class, Service.Mode.MESSAGE);  
  
  
SOAPMessage msg = MessageFactory.newInstance().createMessage();  
SOAPEnvelope ele = msg.getSOAPPart().getEnvelope();  
SOAPBody body = ele.getBody();  
  
  
QName name2 = new QName(ns, "login", "tns");// <tns:login xmlns=""  
SOAPBodyElement element = body.addBodyElement(name2);  
element.addChildElement("username").setValue("1111");  
element.addChildElement("password").setValue("222");  
msg.writeTo(System.out);  
SOAPMessage response = dispatch.invoke(msg);  
System.out.println("\\n服务器响应回来");  
response.writeTo(System.out);  
// 获取返回信息的文档对象  
Document document = response.getSOAPPart().getEnvelope().getBody()  
.extractContentAsDocument();  
System.out.println();  
  
System.out.println(document.getElementsByTagName("login").item(0)  
.getTextContent());  
  
\}
