A "portal" is a browser-based container populated by small applications called "portlets". Good portlets need to work independently, but also communicate with the portal, other portlets, and outside servers and information sources. Whether they're part of internal or web-facing portals, high-quality portlets are the foundation of a fast, flexible, and successful development strategy.Portlets in Action is a comprehensive guide for Java developers with minimal or no experience working with portlets. Fully exploring the Portlet 2.0 API and using widely adopted frameworks like Spring 3.0 Portlet MVC, Hibernate, and DWR, it teaches portal and portlet development by walking the reader through practical examples that incorporate key features and challenges. The accompanying source code can be easily adapted and reused by readers.
