This book focuses on teaching by example. Every chapter provides an overview, and then dives right into hands-on examples so you can see and play with the solution in your own environment. All code samples run on both the latest Enterprise and Community releases. This book will be most useful to professional Java developers who want to build custom web sites, portals, and highly customized intranet applications using Liferay portal as a framework. This book is for Java developers, and you will get most from the book if you already work with Java but you need not have prior experience on Liferay portal. Although Liferay portal makes heavy use of open source frameworks such as Spring, Hibernate, Struts, and Lucene, no prior experience using these is assumed.
