There are so many extension-less web programming in Web developement environment such as Ruby, PHP, JSP and so on. Among them, I want to tell about the simple coding of JSP. Honestly, I'm just beginner to learn JSP, especially J2EE. Because, I just want to know some applications based on Sun Java. Ok, let's go...

Here is simple JSP file and named as greeting.jsp

view plain print about
1<html>
2<body>
3    Hello World! <br>
4    Current time is <%= new java.util.Date() %>
5</body>
6</html>
And create web.xml file and here is coding needed to be in this file.

view plain print about
1<?xml version="1.0" encoding="ISO-8859-1"?>
2<!DOCTYPE web-app PUBLIC '-//Sun Microsystems, Inc.//DTD Web
3Application 2.3//EN' 'http://java.sun.com/dtd/web-app_2_3.dtd'>
4<web-app>
5<display-name>Hello2</display-name>
6<description>no description</description>
7<servlet>
8<servlet-name>greeting</servlet-name>
9<display-name>greeting</display-name>
10<description>no description</description>
11<!-- what gets called -->
12<jsp-file>/greeting.jsp</jsp-file>
13</servlet>
14<servlet-mapping>
15<servlet-name>greeting</servlet-name>
16<!-- URL from browser -->
17<url-pattern>/greeting</url-pattern>
18</servlet-mapping>
19</web-app>

Then, open tomcat manager and create folder name as hello. Create build folder, then copy above greeting.jsp file in this folder, then create WEB-INF folder in build folder. Finally, web.xml file into WEB-INF

Open your Internet Explorer or Firefox, and can run as http://localhost:8080/hello/greeting. How? It's quite simple, right?
