Struts framework

Struts is an open source MVC architecture created to make it easier for developers to build web applications based on Java Servlet and Java Server pages . In a J2EE based application, MVC architecture is used for separating business layer functionality  from Presentation layer functionality represented by JSPs (the view) using an intermediate servlet based controller.

The incoming HTTP requests are routed to a central controller, which in turn interprets and delegates the request to the appropriate request handlers.

 Struts also provides the following modules like   

Struts Validator for form validation.

Tiles for assembling composite views.

Internationalization

Exception Handling
