急急急,我有一个JSP的注册页面怎么将它提交给另一个页面显示登陆成功???

register.jsp<script language="javascript" type="text/javascript">
function checkForm(){
var uname=document.getElementById("username").value;
if(uname.length<6){
  window.alert("Error: the length of username less than 6!");
  return false;
}......
<body>
<form name="form1" method="post" action="">
  <span class="STYLE4">用户注册</span>
  <p align="left">用户名
.........<p align="left">
    <input type="submit" name="Submit" value="提交" onClick="javascript:checkForm">
    <input name="reset" type="reset" id="reset" value="重置">
</p>
</form>
</body>
</html>
doRegister.jsp<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<%@page import="Javabean.RegForm"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
</head>
<body>
<jsp:useBean id="regbean" class="Javabean.RegForm"></jsp:useBean>
<jsp:setProperty name="regbean" property="*"/>
<%
if(regbean.register()==1){
%>
注册成功
<%}else{ %>
注册失败
<%} %>
</body>
</html>
调用方法为:
public int excuteUpdate_id(String sql){
int result=0;
try{
conn=DriverManager.getConnection("jdbc:odbc:bookstore" );
stmt=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
result=stmt.executeUpdate(sql);
String ID="SELECT @@IDENTITY as id";
rs=stmt.executeQuery(ID);
if(rs.next()){
int autoID=rs.getInt("id");
result=autoID;
}}catch(SQLException ex){
result=0;
}

return result;
}

注册页面---》登陆成功你的跨度大了点吧
在控制器中转向或重定向
如果要在一个页面根据是否登陆显示不同的东西。可以用C：if
无语!<form method='get/post' action="你要提交的jsp页面"/>
现在代码改了,出现了这么个错误,请问怎么解决啊????
