Abstract


Portal Portal, as a next-generation desktop, a Web-based system, which provides a unified access portal to access enterprise back-office applications and a variety of heterogeneous resources, provide personalized, single sign-on and application integration capabilities . Build the Portlet Specification Portal platform has become one of the key research direction of the enterprise information construction. Thesis, lightweight framework based the Portlet API Portal platform of key technologies, including lightweight container architecture-based Portal platform mechanism and Portal platform for a complex portal product architecture portlet application portability poor the status quo, Advanced features-Portlet collaboration, research. Portal technology concepts and features, the paper discusses the currently popular Portal and Open Source Portal project, and comparative analysis of the strengths and weaknesses of the existing Portal framework. On this basis, a lightweight framework to build Portal platform to solve the traditional, the EJB J2EE architecture-based Portal platform brings complex issues. The paper focuses on the lightweight container architecture Portal platform architecture design; lightweight IoC container, component-based development concept framework the Portal platform's implementation mechanism; Portal platform key technologies such as the Portal page aggregation technology, based on the the IoC lightweight service container management mechanism, the portlet container implementation mechanisms and Portlet MVC framework with research. The Portal application integration key to solve the problem of the interaction between the various applications, the Portlet Application able to communicate with each other in order to complete the work together, but the JSR 168 specification does not support Portlet communication. Paper also Portlet coordination mechanism Portal platform. Portlet types of collaboration, design and implementation of a new AOP-based the Portlet collaborative framework. Collaborative framework for the use of the AOP technology to extend the Portlet API through collaboration controller at the same time acts as an intermediary, the collaboration between the Portlet logic. The framework by introducing a non-invasive Porlet communication mechanism to ensure that the custom of the Portlet application independence, better support collaborative processes. Finally, given the realization of a framework based on lightweight the Portal platform prototype system.
