java客户端代码 java客户端程序开发

IT技术String

java2wsdl生成的客户端代码怎么调用首先，你要先把你的WS服务启动起来，就是比如ht tp:/ /localhost:8080/Example/services/HelloWorldService?wsdl
然后在你的另一个项目中建一个Webservice Client 客户端，用来访问你的WS服务 。
建立Webservice Client 方法如下 ， 在Eclipses中建立一个java工程，然后在src上右键--NEW---Other---Web Service Client --Xfire--在WsdL url 中写上htt p:/ /localhost:8080/Example/services/HelloWorldService?wsdl-----下一步结束 。
在src里的会出现一些java文件，你找一个以Client结束的java文件，在里面的main方法中会有个service对象，现在你就可以直接用这个对象了，service.peerstatus(参数)这样写就行了 。
急求一段JAVA代码 ， 有关客户端和服务器的 。。。客户端

java webservice生成的客户端代码 需要哪些jar包1、安装环境 J2SE SDK 1.4 ， Tomcat 5.0，eclipse 3.2 。
2、下载Axis安装包 。
3、将Axis相关包文件放在WEB-INF\lib目录下 。
4、Axis可选的包：activation.jar； mail.jar； xmlsec-1.4.Beta1.jar拷贝到WEB-INF目录下 ， 生成客户端时候需要使用 。
Axis支持三种web service的部署和开发，分别为：
1、Dynamic Invocation Interface （DII）
2、Dynamic Proxy方式
3、Stubs方式
建议我们使用Stubs方式，因此我就主要就介绍一下第三种方式 。
注意，Java源代码是放在D：\workspace\test\目录下，Axis相关包文件放在D：\workspace\test\WEB-INF目录下 。
用java代码实现客户端与服务端建立连接？套接字 Socket
import java.net.*;
Server:
ServerSocket server=new ServerSocket(port);//port是端口
Socket socket=server.accept();
//等待客户机的连接请求java客户端代码，若连接，则创建一套接字，并将返回 。
Client:
Socket socket=new Socket("host",port);//host主机名（本机java客户端代码：127.0.0.1）
Java客户端调用Webservice接口求代码客户端获得自定义对象包路径必须和服务器端相同，当然在客户端也可以不用建该对象，可以将客户端的自定义对象打成jar包 ， 然后在客户端引用 。
猜想用反射也可以实现改对象，但目前没有写相关例子 。
pimport java.io.Serializable;/pppublic class Hello implements Serializable {
/**
*客户端必须有与服务器端相同的自定义对象
*/
private static final long serialVersionUID = 1L;
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
