Web pages with JavaServer Faces

JavaServer Faces (JSF) Web components provide a web page user interface for an EGL application.

In practice, using JSF typically involves drag-and-drop components in the workbench. To get a basic understanding of the concepts involved, refer to the EGL Programmer's Guide and the EGL tutorials.

In this type of interface, JSF handlers (Handler parts with the JSFHandler stereotype) provide the logic and manage the data for JavaServer Pages (JSP) files. Typically, there is a one-to-one relationship between JSP files and JSF handlers.

The JSP and the JSF handler interact in the following basic ways:

JSF handlers can access the data that is passed along with the user's session and request objects. See "EGL library j2eeLib." JSF handlers can call EGL programs and other JSF handlers.
