The Composite Application Framework (CAF) component libraries contain controls that are displayed in the Palette view of the UI Development perspective. You can also associate other component libraries that do not appear by default in the Palette view.

When you create a web or portlet application project, CAF includes the CAF Base Controls, CAF Base Runtime, and CAF Java Logging component libraries. When creating a new web or portlet application project, you can add other component libraries such as CAF JDBC Drivers, CAF JCR Client and CAF Portlet Controls. For more information, see Views in the Composite Application Framework.

You can also make these component libraries available on the server by including them in the web archive (WAR) file for the application.
