由於項目裡面需要用到Java調用PHP的儲值介面，所以學習了一下，以下這個Demo是個小小的例子，寫下來做個筆記>

jsp頁面：

 <%@ page language="java" import="java.util.*" pageEncoding="utf-8" contentType="text/html; charset=GBK"%><% String path = request.getContextPath(); String basePath = request.getScheme() + "://"   + request.getServerName() + ":" + request.getServerPort()   + path + "/";%><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"> <head>  <base href="<%=basePath%>" />  <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />  <meta http-equiv="x-ua-compatible" content="ie=7" />  <title>Lost Crown</title>  <link rel="icon" href="favicon.ico" />  <link rel="shortcut icon" href="favicon.ico" /><script type="text/javascript">function getXmlHttp(){    var http_request = false;    if (window.XMLHttpRequest){        http_request = new XMLHttpRequest();        if (http_request.overrideMimeType){            http_request.overrideMimeType(‘text/xml‘); }   }else if (window.ActiveXObject){        try{            http_request = new ActiveXObject("Msxml2.XMLHTTP");        } catch (e){            try{                http_request = new ActiveXObject("Microsoft.XMLHTTP");            }catch (e) {            }        }    }    if (!http_request){        alert("不能建立對象！");        return false;    }    return http_request;}function result(){    if(req.readyState == 4 && req.status == 200){     var names =  req.responseText;     alert("Hello:"+names);    }    }function checkTest(){ var name = document.getElementById("name").value;    var ul = "http://localhost:8011/TestAjax/index.php?name=" + name;    req = getXmlHttp();    req.onreadystatechange = result;    req.open("POST",ul,true);    req.setRequestHeader(‘If-Modified-Since‘, ‘0‘);    req.send(null);}</script></head> <body>   <center>   <table width="300" border=1>   <tr align="center">    <td colspan="2">     It‘s A Ajax Test    </td>   </tr>   <tr align="center">    <td>     使用者名稱    </td>    <td>     <input type="text" name="name" id="name" value="Jerry"/>    </td>   </tr>   <tr align="center">    <td colspan="2">     <input type="button" name="submit" id="submit" value="提交" onclick="checkTest();"/>    </td>   </tr>  </table>  </center> </body></html>

php頁面：

<?php$username = $_REQUEST[‘name‘];echo($username);?>
