With the development and wide application of high-speed networks and information technology , many of the information systems used in business, government and research institutes , and greatly promote the construction and development of these units . However, because there is a big difference of platforms and technologies used in information systems , resulting in these systems are independent of each other , information and data can not be shared duplication of development , the system functions a series of problems such as a serious impediment to the overall process of information construction . How to solve the problem of the \Building information portal system can effectively solve the above problems . Information portal system can integrate existing applications , and it has a single sign-on , personalization , data organization and function . Many technical building information portal system , portal technology has great advantages . Portal technology is based on the JSR168 standard specification , and is supported by multiple open source platform can be widely used in enterprises, universities and government information portal system . This article is based on portal technology to design and information portal system . This paper describes the information portal of the concept and its architecture , focuses on two standard specification JSR168 information portal the WSRP and portal portal core technology and its key components portlet , described from the principles of architecture . Clear demand , make overall planning , information portal system proposed based the portal information portal system design and to be instantiated . Based on the the Jetspeed ease of management , open platform, and feature-rich , and many other fine features , selected open source portal platform Jetspeed portal development , the information portal system integration of existing applications and new design and development ANM ( Network Management Research Center ) information systems , and integrated into the portal system resources and applications through the portlet deployment of existing portlet and new development , but also to achieve a single sign-on , customization features . The study is of universal significance , has considerable practical value .
