Building Portals with the Java Portlet API - The Portlet Life Cycle

By Jeff Linwood and David Minter

01 Aug 2004 |

TSS has excerpted a sample chapter from the 'Building Portals with the Java Portlet API' book, by Jeff Linwood and David Minter. The chapter discusses how a portlet interacts with a portal, from initialization to removal and provides an example that walks you through the stages of the portlet life cycle, and one that illustrates the issues of multithreaded portlet applications.

Linwood and Minter describe 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 Lucene search engine, personalization, portlet configuration, portlet preferences, and Web Services for Remote Portals (WSRP).
