Improved MVC for J2EE Architecture

The model view controller (MVC) is a fundamental design pattern for the separation between user interface logic and business logic. Since applications are very large in size these days and the MVC design pattern can weak the coupling among the different application tiers of application. this paper presents a web application framework based on MVC in J2EE platform, and extends it with XML so that the framework is more flexible, expansible and easy to maintain. This is a multi tier system including presentation layer, business layer, data persistence layer and database layer. This separate codes, and improve maintainability and reusability of the application. In this paper proposes a fusion model to reinforce MVC architecture, where we are trying to display different types of error on same page with the help of try catch and finally block in place of displaying various errors on different pages. In this paper we are displaying the type of error with the help of error code generated by the database server and with the help of try, catch and finally block.
