    • A method, system, and computer program storage device are disclosed for providing security in a mashup comprised of an agglomeration of a plurality of portlets. These portlets are sent from one or more back-end servers, pass through a portal server, and are received by a client browser. The method comprises the steps of developing an isolation boundary between the portlets to isolate each of the portlets from each of the other portlets, and extending said isolation boundary through the portal server and through the browser. Preferably, the portal server bases the isolation boundary on a server-side static analysis and code instrumentation of the portlets. In the preferred embodiment of the invention, each of the portlets is checked for a number of syntactic constraints and marked with a corresponding service domain. The portlets are aggregated into a page-using HTML, and that page is converted into JavaScript.
    • 公开了一种方法,系统和计算机程序存储装置,用于在由多个portlet的聚集组成的混搭中提供安全性。 这些Portlet从一个或多个后端服务器发送,通过门户服务器,并由客户端浏览器接收。 该方法包括以下步骤:开发Portlet之间的隔离边界,以将每个portlet与每个其他Portlet隔离开,并通过门户服务器和浏览器扩展隔离边界。 优选地,门户服务器将隔离边​​界基于portlet的服务器端静态分析和代码检测。 在本发明的优选实施例中,检查每个portlet的多个句法约束并用对应的服务域标记。 portlet被聚合成一个页面使用的HTML,该页面被转换成JavaScript。
