Writing an Administrative Portlet

Like the prototype, the real application lets users add and view guestbook entries. The application’s back-end, however, is much more powerful. It can support many guestbooks and their associated entries. Despite this, there’s no UI to support these added features. When you create this UI, you must also make sure that only administrators can add guestbooks.

To accomplish this, you must create a Guestbook Admin portlet and place it in Liferay Portal’s administrative interface–specifically, within the Content menu. This way, the Guestbook Admin portlet is accessible only to Site Administrators, and users can use the Guestbook portlet to create entries.

In short, this is a simple application with a simple interface:
