jsp连接数据库，帮帮忙，谢谢

我的jsp环境是jdk+tomcat5.0+sql server 2000（个人版），在winxp系统下。我打开sql server 2000企业管理器，在microsoft sql server ——》（local）（Windows NT） ——》数据库下建立了一个数据库叫jspsql，在这个数据库下面新建了一个表叫student：
id 姓名学号专业性别
1 张三 123 计算机男
2 李四 456 化学男
3 李琴 789 数学女
请问我怎么才能把这张表里的所有数据读取到一张jsp页面中去？？？？（我用jdbc驱动连接，不要用jdbc-odbc桥接器）
jdbc驱动也已经安装好了，然后我用了如下代码jdbc.jsp:
<%@page import="java.lang.*, java.io.*, java.sql.*, java.util.*" contentType="text/html;charset=gb2312"%>
<html>
<body>
<%Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=jspsql";
String user="sa";
String password="123456";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select * from student";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next())
{

out.print(rs.getInt("id"));
out.print("<br>");
out.print(rs.getString("姓名"));
out.print("<br>");
out.print(rs.getString("学号"));
out.print("<br>");
out.print(rs.getString("专业"));
out.print("<br>");
out.print(rs.getString("性别"));
}%>
<%out.print("数据库连接成功，恭喜你");%>
<%
rs.close();
stmt.close();
conn.close();
%>
</body>
</html>

但是出现错误了，错误代码如下：
HTTP Status 500 -

数据库连接出错了.查看jar文件有没有问题,看看端口是否禁用
