执行�?br />控制台输出：(x��)

Java6发布了，其中一个吸引我的新�Ҏ(gu��)��就是原生支持WebServices。在�q�和大家分��n下学�?f��n)心得�?br>下面��开始写个最��单的WebServices�Q?br>

package org.hermit.study.jdk;

import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;

@WebService(targetNamespace = "http://jdk.study.hermit.org/client")
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class Hello {
    @WebMethod
    public String sayHello(String name) {
        return "hello:" + name;
    }
}

怎么��L(f��ng)��z�吧�Q�很多朋友的写法�q�要在命令行中执�?#8220;wsgen –cp . ”
用偶�q�种�Ҏ(gu��)��写的service可以省去上面�q�步�?br>
targetNamespace = "http://jdk.study.hermit.org/client"�q�句是指定客��L(f��ng)��获取服务端服务后存放的类路径。注意是反着的，http: //jdk.study.hermit.org/client在客��L(f��ng)��生成的类�?x��)放在org.hermit.study.jdk.client包下�?br>下面是发布服务：(x��)

package org.hermit.study.jdk;

import javax.xml.ws.Endpoint;

public class StartService {
    public static void main(String[] args) {
        Endpoint.publish("http://localhost:8080/HelloService", new Hello());
    }
}

呵呵�Q�更��z�。一句话而已�?br>http://localhost:8080/HelloService是指发布的地址

�q�行StartService �Q�开发浏览器输入�Q�http://localhost:8080/HelloService?wsdl

如果能看��C��下内容，��可�?br>
