JSF is a Web framework for developing Component oriented web applications in the User Interface layer. Amongst the various capabilities that JSF provides, one of the major strengths of JSF is that it is not tied to any specific target device. For example, currently most of the JSF applications are running in a web server and are accessible through a web browser. However, web browser is not the only target for a JSF application to be viewed; it can be even accessed through a hand-held device, for example through a mobile phone. In this example, we will see how to develop JSF applications targeted for mobile phones. This article assumes that the reader has a good understanding of JSF, its life-cycle and some understanding on JSF renderer kits.

The official GUI classes for the J2ME are included in profiles such as the MIDP and are defined by the Java Community Process (JCP). The GUI classes in the MIDP are not based on the Abstract Window Toolkit (AWT). The limited CPU memory of handheld devices, cannot handle the AWT.
