一种多Portlet之间交互方法的研究

Study on Approach of Interactive Multi-Portlet

J2EE企业应用中,Portal作为一种信息和资源整合模式,能够有效地整合信息资源。Portlet是Portal Web应用的重要组件。在实际的应用中,多Portlet交互共同完成一项任务已经相当普遍,而在现有的Portlet标准JSR-168中,没有定义多Portlet交互的方法和实现,难以满足Portal的应用需求。该文在JSR-168标准的基础上,通过扩展Portlet实现接口、增加Portlet交互描述等方法生成AAFPortlet来实现多Portlet之间的交互,并将此方法在开源的eXo中实现,应用于实际系统,效果显著。

As a kind of information and resources integration paradigm, Portal can effectively integrate information resource in the J2EE enterprise application. Portlet is the important component of Portal. In the actual application, it is quite ubiquitous that multi-Portlet together complete a task. However, the current Portlet criterion （JSR-168）, doesn＇t define approach and realization of multi-Portlet interaction, which doesn＇t satisfy the demands of Portal application. By extending implement interface of Portlet, increasing interactive describe of Portlet and so on, AAFPortlet is produced to implement multi-Portlet interaction, based on JSR-168 standard. It is implemented in eXo and used in the practical application system. The effect is remarkable.
