Apache Myfaces and Tomahawk

JSF provides rich set of components that makes easy and fast to create GUI for web application. JSF is a specification that has been  implemented by many venders like Apache, Sun, Oracle etc. Because of several implementations you may not decide which implementation to use. JSF implementations also provides many components and many third party component vendors are available to use components provided by them. Among these many implementations Apache MyFaces implementation provides a lot of components that are typically needed in creating web forms. You would not require to create your own component. Tomahawk is a set of some new and standard components with extended functionality.

1. Introduction to Apache Myfaces and Tomahawk
   There are several implementations for JSF specification. Sun, Apache, Oracle implementations are most popular among JSF developers. Apache MyFaces is an Apache Software Foundation's project .This is an open source JSF implementation.
        
2. Downloading and exploring MyFaces examples integrated with Tomahawk
   If you are beginner in the field of JSF framework then really its necessary to follow the examples provided by any source. Here apache itself has provided examples in a zipped format. These examples are good implementation of Tomahawk components.
       
3. Exploring Examples
   Examples provided by the myfaces-example-simple-1.1.6.war file provides the code for every example. You can go through these examples. In this tutorial some examples have been described to help you out understanding the usage of components.
      
4. Tomahawk Tags :
