基于jetspeed的信息门户的设计与开发
 
摘要：随着互联网的迅速发展,各种信息服务技术层出不穷,Portal就是其中1种。Portal即门户，是1种不断发展和完善的技术:人们可以通过对它的单1访问来获取互联网上的多种信息。随着门户应用领域的扩展,出现了企业信息门户。
主要对企业信息门户进行了研究，主要分析了门户产品Jetspeed的架构及应用。其中包括对portal、portlet、portlet container以及JSR168规范的研究。第1章主要是对Portlet的定义，以及Jetspeed的概念和其发展历程进行了介绍。然后在第2章对Jetspeed-2的原理，工作流程和其安全机制，集成环境进行了比较详细的说明。在接下来的第3章阐述了与其相关的技术与规范，其中包括Portlet页面的创建，Portlet与Servlet的关系，Portlet的界面，Portlet模式，Portlet的窗口状态，Portlet的生命周期，Portlet的请求与响应和PSML语言。在的最后给出了1个在Jetspeed下开发1个遵循JSR168的实例。

Besign and Development of Information Portal Based on Jetspeed

Abstract： With the rapid development of the Internet, various information service technologies have appeared, one of which is Portal. Portal is a continuous developing technology, just by visiting which people can abtain much information from internet. With the expanding of its applicating field, the enterprise information portal has appeared. The thesis mainly studies the enterprise information portal, and analyzes the structure and the application of the portal product--Jetspeed, including studying  of portal、portlet、portlet container and JSR168.
   The thesis consists of four chapters. First, it introduces the definition of Portlet, the concept of Jetspeed and its developing proccess. Second, it deals with the principle, the working proccess, the safety system and the environment of Jetspeed-2. Third, it talks about the relative technologies and standards, including the creating of the webpage, the relation between Portlet and Server, the stage, mode, the windows situation, the life expansion, the require and reply of Portlet, and SML. Fourth, it sets a simple example for exploitation of Portlet of Jetspeed.
