Summary

This book is a thorough introduction into JSR 168 that will help get portal developers up to speed into this relatively new specification. - Thomas Paul, JavaRanch SheriffHow do developers bring existing applications into a portal? How do developers integrate content management systems and search engines with a portal? And how do developers get started with the Portlet API? Jeff Linwood and Dave Minter show you how to solve these real problems inBuilding Portals with the Java Portlet API.This book describes the new Java portlet API, including security, portlet life cycles, and portlet interaction with servlets and JSP. The examples will work on any portal that complies with the JSR-168 portlet API. Several example portlets are developed to give you hands-on portlet experience. You'll even learn how to port existing servlet and JSP applications into a new portal environment.The authors also discuss Single Sign-On (SSO) using Kerberos and the GSS-API, syndicating content with RSS, and integrating a charting solution with JFreeChart. Other topics covered are the open-source Apache Jakarta Lucene search engine, personalization, portlet configuration, portlet preferences, and Web Services for Remote Portals (WSRP). XDoclet is also used throughout portions of this book.
