3.1. Requirements for the Book Catalog portlet

If you tried running the User Registration portlet (developed in chapter 2) on portal servers other than Liferay Portal, there’s a good chance that it didn’t work at all, or that it behaved differently. The reason for this is that the other portal server is missing support for an optional feature, or there’s an existing bug in the portlet container or portal server software, or there are portal server–specific configuration requirements for a portlet.

In this chapter, you’ll look at a Book Catalog portlet that allows users to manage a book catalog. With the Book Catalog portlet, you can add, remove, search for, and list books in the catalog. This example portlet will help you learn and allow you to implement the concepts described in this chapter.
