This is the Maven project for the custom JSF 2 widgets. The widgets and the resources projects are closely tied together. These widgets will be deployed as a jar file containing Sakai JSF 2 widgets (components). Web applications can include this jar in order to use the Sakai JSF 2 widgets in a JSF tool.

There is a newer version: 23.3
