最近写了一个用户验证密码的程序，其功能如下：
输入用户名和密码，然后提交，只有在密码位数大于8位切有数字的时候，才输出Thank you Your password meets the security policy 否则输出Sorry Your password does not meet the security policy 可是我的不知道怎么了，两个竟然同时输出了！各位大虾帮帮忙啊！谢啦！
login.html文件如下：
<html>
<head><title>A Siple Login Page</title></head>
<body>
<p>Please Login:
<form action=login.jsp method=post>
<p>User Name:<input type=text name=usernameField>
<p>Password:<input type=text name=passwordField>
<p><input type=SUBMIT value=Submit>
</form>
</body>
</html>
login.jsp文件如下：
<html>
<head>
<title>A Simple Jsp That Verifies Password Policy</title>
</head>
<body>
<%! final static int MIN_PSWD_LEN=8;
static boolean verifyPasswordLength(String password){
if(password.length()<MIN_PSWD_LEN)return false;
return true;
}
static boolean verifyPasswordHasDigit(String password){
for(int i=0;i<password.length();i++)
if(Character.isDigit(password.charAt(i))) return true;
return false;
}
static boolean verifyPasswordPolicy(String password){
if(verifyPasswordLength(password)&&verifyPasswordHasDigit(password))
return true;
else
return false;
}
%>
<%String password=request.getParameter(passwordField);
if(verifyPasswordPolicy(password)){%>
<p>Thank you
<p>Your password meets the security policy
<%}else{%>
<p>Sorry
<p>Your password does not meet the security policy
<p><a href="login.html">Please Try Again</a>
<%}%>
</body>
</html>
在众多好心人的帮助和启发下，我无意中改了一下文件类型，将.html改成.jsp ， 就好用了！！我想问一下，这个和我的编译环境有关吗？我用的是Eclipse3.2--jdk1.5--jre1.5 。 还是另有其因？如果这样可以的话，为什么不把所有的html都换成jsp呢？

此程序没有任何问题
<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

%>
<p>Sorry

<p><a href="login.html">Please Try Again</a>
<%
}
%>
</body>
</html>
就是加了点符号
