This document provides an overview of the Apache Struts 2 framework. It discusses that Struts 2 is an open-source MVC framework built on top of Servlets and JSP technologies. It takes complexity out of building web applications and encourages good design practices. The document then outlines the basic steps to create a simple Struts 2 application, including writing JSP pages and action classes, configuring the struts.xml file, building and deploying the application.

6. Steps
1. Write JSP pages (View)
2. Write Action class (Model)
3. Forward at either success or error
through configuration set in struts.xml
4. Build, deploy, and test the application

8. JSP Pages
 Write one JSP page for each view
 Use Struts tags for
 Handing HTML input forms
 Writing out messages

12. Action Class
Extend com.opensymphony.xwork2.ActionSupport
class
 Decide set of properties that reflect the input form
 Write getter and setter methods for each property
 Write execute() method

15. struts.xml
 Identify required Action's and then define them as
