中文摘要：

企业信息Portal作为企业信息集成的工具,主要是基于Portlet在表现层进行集成。这种集成实质上就是Portlet之间数据交互问题。在分析现有数据交互方法基础上,遵循JSR-168和WSRP规范,通过扩展Portlet实现接口,提出了多Portlet数据交互框架,并基于XML技术封装交互信息,实现Portlet之间信息交互。

英文摘要：

Portals are a means integrating entergration information through a portlet,which is a presentation component.It is the essence of data interaction between portlets.This paper proposes an approach for extending the interface of a portlet and implementing a portlet cooperation by supporting the communication between portlets.The approach is based on an established portlet Specification,a WSRP Specification,and an analysis of existing data exchange methods.This approach allows the exchange message of structured XML between portlets to complete the work together.
