大家帮帮忙，我用JSP编写了一个程序，想用表格输出数据库里的内容，大家帮我看看代码，在哪个地方添加表格啊
代码：<%@page contentType="text/html;charset=GBK" import="java.sql.*"%>
<html>
<title>用户注册：使用JDBC处理用户提交数据</title>
<body>
<%
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb?user=root&password=12345&useUnicode=true&characterEncoding=GB2312");
Statement stmt = con.createStatement();
String upd = "INSERT INTO userinfo(username,password) "+ "VALUES ('222','333')";
stmt.executeUpdate(upd);
String query = "SELECT * FROM userinfo";
ResultSet rs = stmt.executeQuery(query);
while(rs.next()){
out.println(rs.getString("username")+"----"+rs.getString("password"));
}
rs.close();

一楼的不对
代码改为:
ResultSet rs = stmt.executeQuery(query);
%><table><tr>
<td>姓名</td>
<td>密码</td>
</tr></table><%
while(rs.next()){
%>
<tr>
<td><%=rs.getString("username")%></td>
<td><%=rs.getString("password")%></td>
</tr>
<%
}
%>
</table>
<%
while(rs.next()){
out.println(rs.getString("username")+"----"+rs.getString("password"));
}
改成
while(rs.next()){%>
<table><tr><td>用户名</td><td>密码</td></tr>
<tr><td><%=rs.getString("username")%></td>
<td><%=rs.getString("password")%></td>
</tr>
</table>
<%}
