Research And Implementation Of Web Application Integration Based On Portal Technology

With the development of enterprise information, all kinds of different applications based on different platforms are producing. However, these applications are independent and make of decentralized data, and difficult to collaborated, which forms information isolated islands. These applications become more and more complexity, at the same time users' convenience requirements of access to information are constantly improved. According to such development trend, the enterprise application integration becomes a practical study for us. The formation of enterprise portal provides an important solution for enterprise application integration. Enterprise Portal will be responsible for different applications and data and integrate then into a unified information management platform, provide the unified entrance and the personalized configuration. It is generally acknowledged to be the next generation enterprise application desktop.In view of enterprise portal exist a huge potential commercial value, the major manufacturers have begun to produce its own enterprise portal products. As there is no uniform standard for enterprise portal product development at early time, enterprise portal development was seriously restricted. JSR168 and WSRP specification have launched one after the other. JSR168 specification specifies the standards portlet APIs and portlet runtime mechanism, while WSRP specification provides using remote portlet mechanism. These two specifications make the development of enterprise portal gradually become standardized, while also promoting the development of the enterprise portal.The main task of this thesis include: introduce to the enterprise application integration and enterprise portals briefly and analyze the JSR168 and WSRP specification roundly. Based on portal technical integrate the struts 2 web application into enterprise portal—Jetspeed-2 which supported JSR168 specification, as well as implement single sign-on of web application; optimize the portlet communication mechanism, and propose an adaptive mechanism to improve user access portal experience. Finally, integrate module of WSRP4J project into enterprise portal, so that can share the application which integrates to enterprise portal.
