利用xml+xsl快速生成大量JSP的常用代码的方法.

摘要: 利用xml+xsl快速生成大量JSP的常用代码的方法.

利用xml+xsl快速生成大量JSP的常用代码的方法. 参考Jbuilder的Servlet向导来使用xml+xsl产生JSP的常用代码。xml样本: <?xml version="1.0" encoding="GB2312"?>
<?xml-stylesheet type="text/xsl" href="jspram.xsl"?>


rloginusername
loginusername
String
request
lizongbo
用户的登录名


clastlogintime
lastlogintime
long
cookie
0
用户最近一次的登录时间


suserpass
userpass
String
session
password
存放在session里的密码


xsl文件略。 转换后的效果图和相关代码：

testjsp.jsp
