Application Research On Enterprise Information Portal Based On Portlet

As all kinds of heterogeneous applications in enterprise systems come with the multi-development of software, each system has its independent way of Login, user interfaces and storage system, which makes the cost of user's operation and maintenance increase continually. The isolation between the various application systems makes major constraint for enterprise resource sharing and reusing. Therefore, there is an urgent requirements for a unified system to resolve the problem of information isolated island, and it makes system frameworks to coordinate work and improve the competitiveness of enterprises.In view of the above problems, this thesis introduced an enterprise information portal (EIP) framework based on Portlet, and adopted Portlet technology to achieve the EIP system of WISCO Equipment Centre.The research of this thesis rooted in the enterprise portal projects of WISCO Equipment Centre. The main tasks of this thesis include: Analyzing the development of the Portal and the composition of Portlet, and expounding the concept of enterprise information portal. Then the thesis presented a Portlet application model of enterprise information portal based on JSP and MVC design pattern through integrated research on Struts Portlet technology. The thesis used the model to analysis the EIP system of WISCO Equipment Centre and used the object-oriented and UML technology to design the business process of user authority management subsystem and the business processes of device management subsystem in accordance with divisions of the data layer, the business logic layer and the presentation layer. Finally, the Portlet application model is used to integrate Web Application, and the centre WISCO equipment EIP system was realized.In addition, this thesis resolved the issue of information sharing of enterprise resource through integration of enterprise applications and portal. Meantime, the thesis provided a more flexible solution for enterprise information integration through the combination of Struts Portlet model and the iBATIS framework. It was a worth reference for various application of technical framework in the Portal and was a useful exploration.
