In this excerpt from Java Portlets 101, author Sunil Patil explains how portlets can include markup generated by servlets or JSPs, as well as how to dispatch requests to JSPs for actual markup generation and how to dispatch requests to servlets. He also discusses how to use various tags defined in the portlet tag library, using servlets to display images in a portlet, and restrictions on markup generated by a portlet.

Does anyone really need a book on Portlets? I thought the JSR 168 was cake reading. I mean, the Specs basically sit upon the Servlet API with a few enhancements to take into account that each Portlet is really a mini Servlet (The name even reflects this) with a twist.

Does the book include examples of WSRP producers and consumers?
