J2EE-Struts With Hibernate Framework
In a standard Java EE web application, the client will typically call to the server via a web form. The information is then either handed over to a Java Servlet which interacts with a database and produces an HTML-formatted response, or it is given to a JavaServer Pages (JSP) document that intermingles HTML and Java code to achieve the same result. Both approaches are often considered inadequate for large projects because they mix application logic with presentation and make maintenance difficult. The goal of Struts is to separate the model (application logic that interacts with a database) from the view (HTML pages presented to the client) and the controller (instance that passes information between view and model). Struts provides the controller (a servlet known as ActionServlet) and facilitates the writing of templates for the view or presentation layer (typically in JSP, but XML/XSLT and Velocity are also supported). The web application programmer is responsible for writing the model code, and for creating a central configuration file struts-config.xml that binds together model, view, and controller.

JEE is a framework that defines the standard for developing multi-tier enterprise applications. It simplifies enterprise applications by basing them on standardized, modular components, and it provides a complete set of services to those components. Introduction to Object/relational mapping framework for enabling transparent POJO persistence and build persistent objects using common OO programing concepts. Allows developers focus on domain object modelling not the persistence plumbing. Sophisticated query facilities. Struts2 is popular and mature web application framework based on the MVC design pattern. Struts2 is not just the next version of Struts 1, but it is a complete rewrite of the Struts architecture.
