jsp页面不能自动跳转了
代码如下：<%@ page language="java" contentType="text/html; charset=gbk" errorPage=""
pageEncoding="gbk"%>
<%@ page import="java.sql.*"%>
<%@ page import="java.util.*"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<body>
<div>

//处理中文乱码
request.setCharacterEncoding("GB2312");
//获取用户名
String sUserName = (String)request.getParameter ("username");
//获取密码
String sPassWord = (String)request.getParameter ("password");
//获取单选框信息
String userinfo = (String)request.getParameter("RadioButtonList1");
out.println(sUserName);
out.println(sPassWord);
out.println(userinfo);
try {
//登记JDBC驱动程序
Class.forName ( "com.microsoft.sqlserver.jdbc.SQLServerDriver");
String url = "jdbc:sqlserver://localhost:1433;DatabaseName = SelectClass";
//建立连接

out.println("数据库连接成功！");
//SQL语句
String sql = "select * from "+ userinfo +" where username='" + sUserName + "'";
//String sql2 = "select * from Student where password = '" + sPassWord + "'";
Statement stmt = conn.createStatement ();
ResultSet rs = stmt.executeQuery(sql);
out.println("id");
if(rs.next()) {
String rsPWD = rs.getString("password");
out.print(rsPWD); //能够执行到这一步
if(sPassWord.equals(rsPWD.trim())) {
%>
<script type="text/javascript" language="jacaScript">

out.println("页面跳转成功！");
}
</script>
<%
session.setAttribute("username",sUserName);
session.setAttribute("password",sPassWord);
//+页面跳转语句；页面还是无法跳转···
return;
} else {%>

不知道怎么改才能够使页面跳转呢？还有，怎么设置跳转的时间？ --------------------编程问答-------------------- 数据库连接部分都写到JSP里了真汉子？ --------------------编程问答-------------------- js代码中用java代码的变量,咋可能跳转...
页面跳转代码改成java的
if(userinfo == "Student") {
window.location.href="Student.jsp";
out.println("页面跳转成功！");
}
改为
<%
if(userinfo == "Student") {
response.sendRedirect("/Student.jsp");
return null;
}
%>
%> --------------------编程问答-------------------- 你写这个代码 太厉害了。。不知道你看的乱不乱。。response.sendRedirect("/Student.jsp");
页面跳转 --------------------编程问答-------------------- 奇葩啊。。。。。数据库操作都写到JSP里 --------------------编程问答-------------------- 亲，别让 jsp文件做越权的事哦，它基本只负责：输入和输出功能
--------------------编程问答--------------------
不好意思，各位大神，小弟刚刚接触，现在还在尝试javabean，多包涵···还有，多谢各位的耐心回答！小弟谢过···
