Apache Struts is an open source MVC framework for developing Java web applications. It divides applications into three parts - the model contains application logic and database connection code, the view is the user interface like HTML/JSP pages, and the controller acts as an interface between the user and model. Struts uses the MVC pattern to separate business logic from presentation for easy maintenance of web applications.

3. Introduction
• Apache Struts is an open source framework
for web development used by the J2EE
developers for developing web applications.
• It was originally created by Craig McClanahan
and donated to the Apache Foundation in
May, 2000.
• The latest version of struts is 2.3.16.1

4. What is MVC ?
• Model–view–controller (MVC) is a software
architectural pattern for implementing user
interfaces.
• It divides a given software application into
three interconnected parts.
• M – Model
• V – View
• C – Controller

6. Cont’d
• Model – It contains the codes of application
logic and the codes for connecting to the
database.
• View – The view is used to as a user interface.
It is either a HTML or JSP page.
• Controller – The controller acts as the
interface between the user and the model.

7. Why Struts ?
• Struts uses the MVC model.
• The goal of Struts is to separate the model
from the view and the controller.
• i.e., struts avoids mixing up of the business
logic or application logic and presentation.
• Thus struts are easy to maintain.
