JSP+ACCESS做的一个简易论坛

JSP+ACCESS做的一个简易论坛

在JB9+win98下编译成功并能运行,如果大家用JB2005的话,请自己新建一个工程,再建一个web应用程序,再将附件中的JSP文件复印到自己创建的工程下即可运行,数据库用DSN配置一个BBSDSN的数据源,就应该能够运行了.
源码如下,
一. userlogin(登录页面)
<%@ page contentType="text/html; charset=GB2312" %>
<html>
<head>
<script language=JavaScript>
function checkform(formlogin)
{
var flag = true;
if(formlogin.userName.value == "" || formlogin.userName.value == null)
{
alert("用户名不能为空!");
formlogin.userName.focus();
flag = false;
}
else if(formlogin.userPassword.value == "" || formlogin.userPassword.value == null)
{
alert("密码栏不能为空!");
formlogin.userPassword.focus();
flag = false;
}
return flag;
}
</script>
<title>欢迎光临阿当论坛--用户登录</title>
</head>
<body bgcolor=#7ADA93>
<BR><BR><BR><BR>
<p align="center"><b><font size="7" face="华文彩云" color=#006699><span style="letter-spacing: 50">阿当论坛</span></font></b></p>

<p align="center"><span style="letter-spacing: 26"><font face="华文彩云" size="5" color=#006699><b>用户登录</b></font></span></p>

<form method="POST" action="checklogin.jsp" name="formlogin" onsubmit="return checkform(this)">
<p align="center"><font size="3" face="华文中宋" color=#006699>用户名 </font><input type="text" name="userName" size="20"><br>

<p align="center"><input type="submit" value="登录">&nbsp;&nbsp;&nbsp;
<a href=createNewUser.jsp><font size=1 face=宋体>注册新用户</font></a></p>
</form>

<HR size=5>
<TABLE align=center width=37% >
<TR >
<TD><FONT SIZE=1pt COLOR=#006699 face=宋体>由于初学JSP,所以界面简陋,功能简单,敬请原谅!<br>由于经验有限,此论坛只有注册用户才能进入.<br>我的座右铭:努力努力再努力,我一定会成功!</FONT></TD>

//连接数据库，进行查询看是否有此用户
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection cn = DriverManager.getConnection("jdbc:odbc:BBSDSN");
Statement st = cn.createStatement();
String sql = "select * from BBS_USER where USERNAME='" + userName + "' and Password='" + userPassword + "'";

汗啊，当当怎么从C板块流窜到这里来作案了～～
把你的程序打包一下吧

我怎么不能跟贴了.还有一个文件源码,想请问TEXTAREA文本域中的字体怎样设置.没有学JAVABEN,所以暂时只能做成这样了.这个简易论坛暂时只能发贴,与回复贴,呵呵,是不是太简易了点啊,请大家不要见＾○＾.
