So far, we have examined the basic building blocks provided by Simple Portal's tag library. We will now examine an extension provided to allow the display of portlets pretty much as they are rendered in classic portals, that is with decorations. This extension is built on top of Simple Portal's tag library and uses the JSP 2.0 tag library extension feature. A pretty good overview of this feature can be found at http://www.onjava.com/pub/a/onjava/2004/05/12/jsp2part4.html.
