Portlet Wrappers using JavaScript

In this paper we extend the classical portal (with static portlets) design with HTML DOM Web clipping on the client browser using dynamic JavaScript portlets: the portal server supplies the user/passwords for all services through https and the client browser retrieves web pages and cuts/selects/changes the desired parts using paths (XPath) in the Web page structure. This operation brings along a set of advantages: dynamic wrapping of existing legacy websites in the client browser, the reloading of only changed portlets instead of whole portal, low bandwidth on the server, the elimination of re-writing the URL links in the portal, and last but not least, a support for Java applets in portlets by putting the login cookies on the client browser. Our solution is compliant with JSR168 Portlet Specification allowing portability across all vendor platforms. KEYWORDS Web portals design patterns, portlet wrapper.
