A: servlet源码实例
package com.viewlinecn.userlogin.www.servlet;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.lang.StringUtils;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import com.viewlinecn.userlogin.util.OrganizeXML;
/**

*/
public class LoginGameServlet extends HttpServlet {
     private final static long serialVersionUID = -200904271326L;
     private static Log log = LogFactory.getLog(LoginGameServlet.class);
     public void init() throws ServletException {
            //no code
     } public
     void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
           // 添加代码
    } public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
           // 添加代码
    }
}
B: servlet部署
web.xml 中配置<Servlet>...</Servlet>节点
class: com.viewlinecn.userlogin.www.servlet.LoginGameServlet ;
url:    /servlets/login.html
C: 客户端远程调用
URL: http://host:port/context/servlets/login.html
D: servlet开发调用工具
package com.viewlinecn.common.http.util;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.HttpURLConnection;
