摘要
Portlet2.0规范JSR286中定义了基于事件的发布/订阅的Portlet协作方式,但协作依赖于协作事件的定义,降低了Portlet的交互能力,不支持通过Portlet协作重组创建新的协作页面。通过在现有协作框架中引入事件转换机制,解除Portlet协作与事件之间的依赖关系,提高Portlet协作的可重用性,同时给出门户系统中支持事件转换机制的Portlet协作的设计与实现。
JSR286 in Portlet 2.0 Specification defines Portlet coordination pattern based on the Pub/Sub of event. However the coordination depends on event＇s definition, which reduces the interactive ability of Portlet and does not support the coordination pages restructured and innovated via Portlet coordination. In this paper,by importing the event translation mechanism to existing coordination framework, the depend- ence relationship between Portlet coordination and events is severed, and the reusability of Portlet coordination is enhanced. Meanwhile the design and realization of Portlet coordination in Portal system with event translation supporting mechanism are given.
