[[Web programming]] with [[Technology:JSF]]
== Motivation ==
This contribution covers the popular approach for [[web programming]] with [[Technology:JSF]]. [[Technology:JSF]] has a great support for the
development of [[user interface]]s in the [[MVC]] context. This implementation is considered as a typical [[Language:Java]] based implementation with
an amount of related and commonly used [[Technology|]] like the [[Technology:Hibernate]] [[Feature:Persistence|]] [[API]] and
the [[Technology:GlassFish]] [[Application server|]].
== Illustration ==
The main architecture is based on the [[MVC]] pattern. [[Technology:JSF]] itself is focussed on the view and the controller. The [[user interface]]
(view) is provided by [[Technology:Facelets|]], which is based on the [[Language:XHTML]] dialect. A facelet contains the necessary [[GUI]]
components for the specific view and connects them to the corresponding methods of the backend [[Technology:Java Bean|]] (model). The data
provided by the Java Beans is stored within a [[Technology:MySQL]] database, accessible through [[Technology:Hibernate]] with the help of [[DAO]]s
(data access objects). The following sections provide a specific description of the involved parts.
=== GUI development ===
Facelets provide [[Language:HTML]] page generation. Since the XML tags for the JSF components can not be displayed by the browser, they have to be
changed to corresponding HTML tags via component aliasing. The following example shows the JSF components needed for total and cut of a company:
