Design And Implementation Of Agricultural Information Release System Based On JSF And EJB3.0

Shandong Agricultural mechanization has been rapidly developed. While, The computer and network technology based on B/S-style multi-tier architecture of the applications have become mainstream. Increasing agricultural machinery industry information work is the first needing. I have developed the Agricultural Information Release System during the building process of Shandong agricultural machinery website.In the development process, I first had the information submitted by the agricultural machinery Information business process analysis to determine the role, extracting use cases. I had used UML for system needs analysis, object-oriented analysis and design. In the various stages of the establishment of use case diagrams, class diagrams and building diagrams, sequence diagrams, etc. It forms a conceptual model of the system to complete the system. It makes the developers of the system have a clear understanding of the structure and reduces development risks.In the design of application architecture, how to integrate the framework by loosely coupled, way so that each level of mutual cooperation, has brought confusion to the developers for this issue. I adopted JSF, EJB3.0 and JPA framework to develop Web application system. The development of efficient and flexible multi-use system provides a new way and method.Finally, I completed agricultural information release system with JSF and EJB3.0 Framework technologies. The system architecture, using a four-layer architecture, the use of middleware, database access, dynamic page generation system to facilitate system updates and maintenance, enhanced interaction with the user to improve the system's security, It provides effective information release back-office services to realize the sharing of information resources of agricultural mechanization for Shandong Agricultural Information Network.
