jsp页面跳转相对路径问题

环境用的myEclipse 想由1.jsp跳转到2.jsp，其中使用到了相对路径的知识。问题如下：
1.jsp主要代码：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP '1.jsp' starting page</title>

</head>

<body>
<h4>用户登录</h4>
<%out.print(path); %><br>
<%out.print(basePath); %>
<form action="<%=path %>/2.jsp" method="post">
<p><input type="submit" value="提交"></p>
</form>
</body>
</html>
注意：测试中path的值是/test,basePath的值是http://localhost:8080/test/
但现在问题是跳转不到2.jsp，点击“提交后的网址是”：http://localhost:8080/test/2.jsp，正确情况应该是http://localhost:8080/test/test/2.jsp ,
2.jsp中主要代码：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP '1.jsp' starting page</title>
</head>

<body>
<%
out.print(path);
%><br>
<%out.print(basePath); %><br>
<%

if("admin".equals(name) && "admin".equals(pwd)) {
session.setAttribute("user", name);
out.print(session.getAttribute("user"));

}
// response.sendRedirect("index.jsp");
%>
</body>
</html>
