Struts Overview

Struts is an open-source web application framework for developing servlet/JSP based applications. It concentrates on the web tier, and aside from providing a simple JDBC connection pool, does not attempt to address persistence requirements.

It does, however, suggest the use of a domain object model and business logic beans, and its tag libraries include a number of tags for working with JavaBeans.

The Struts framework provides 3 key components:

• A request handler provided by the application developer that is mapped to a standard URI.
• A response handler that transfers control to another resource which completes the response.
• A tag library that helps developers create interactive form-based applications with server pages.

Struts applications have 3 major components:

• A servlet controller, which is provided by Struts
• JSP pages (the view)
• The application's business logic (the model)
