我是靠谱客的博主伶俐裙子，这篇文章主要介绍JSP application（return String）用法详例，现在分享给大家，希望可以做个参考。

1.JSP代码：

复制代码代码如下:

 
<%-- 
Document : Application 
Created on : 2009-10-4, 13:18:53 
Author : lucifer 
--%> 
<%@page contentType="text/html" pageEncoding="UTF-8"%> 
<!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=UTF-8"> 
<title>JSP Page</title> 
</head> 
<body> 
get Server Info: 
<%=application.getServerInfo()%> 
<br> 
get Context Path: 
<%=application.getContextPath()%> 
<br> 
get Real Path: 
<%=application.getRealPath("/Application.jsp")%> 
<br> 
</body> 
</html> 

2.输出：

复制代码代码如下:

 
get Server Info: Apache Tomcat/6.0.18 
get Context Path: /TestMethod 
get Real Path: D:\Program Files\NetBeans 6.7.1\www\TestMethod\build\web\Application.jsp
