Research And Design On Model Of JavaEE Managementlnformation System

JavaEE is an architecture which simplifies the development, deployment and management of enterprise solution with Java 2 platform. Web application development with JavaEE has the advantages of standardized development, modular architecture, platform independence and scalability. The layered model of JavaEE divides application layer from business logic layer, which enables every single part of the system responsible for its own business. That provides great specification for the whole system development.With the in-depth study on the JavaEE architecture, a Graduation Practice and the final Project Management Information System--GPPMIS is proposed based on the light-weighted JavaEE architecture. Well applied JavaEE structure is enclosed in GPPMIS, as well as MVC design pattern and other frameworks like Spring, Struts, Hibernate and AJAX.Also, the design patterns and framework techniques involved with GPPMIS are discussed. The concepts and architectures of Spring, Struts, Hibernate and AJAX are introduced. The whole development process is showed in detail with examples. Strength and weakness are enclosed. The solutions are proposed and applied to GPPMIS.With the complete diploma project management solution, automation of the whole procedure is achieved. The advantages of network resources and distribution are well used. As proved, GPPMIS acquires the inherent scalability, flexibility and ease to maintain of JavaEE. It also outperforms traditional MIS in many ways.
