摘　　要：在J2EE的应用中,越来越多地使用Portal来发布信息。Portal的重要组件就是Portlet。在Portlet开发中,会遇到大量的需要Portlet协作的情况。现有的Portlet1.0规范没有为Portlet协作提供可用的框架,难以满足Portal应用的需求。该文在Portlet1.0规范的基础上,提出了一个Portlet协作框架,并给出了它在两种不同的通信机制下的实现。这个框架已经成功应用于ONCEPortal系统中。Portal is universally deployed and used for publishing information in more and more J2EE applications, Portlet is the component of Portal. In development of Portlet, Portlet cooperation is strongly needed. However, the current Java portlet specification （version 1.0）, doesn＇t provide a usable framework of inter portlet communication, which doesn＇t satisfy the demands of portal application, Based on the standard portlet specification, the paper proposes a framework of portlet cooperation, and the different implementations based on two kinds of communication mechanisms are further introduced. The framework has been successfully applied in ONCEPortal system.
