The API submodule implements all of the classes that are defined in the specification. If you are looking for API documentation about the classes that your JSF application needs to use, then see the javadoc for the API module.
The Impl submodule provides "invisible" support classes that user code does not directly invoke, but which is needed for a working JSF framework. Examples are the renderer classes for the standard JSF components.

These two libraries (myfaces-api.jar and myfaces-impl.jar) are deployed together with your code to form a JSF web application.

If you want to know more about how JavaServer(tm) Faces works, take a look at the documentation referenced from the main MyFaces site.

The JavaServer Faces 1.2 specification was issued on 11 May 2006, and the Apache MyFaces project also provides an implementation of this api. In general, JSF 1.2 should be used unless there are specific reasons to use this older specification.

Requirements

JSF 1.1 requires java 1.3 or later, JSP 1.2, JSTL 1.0, and a Java Servlet 2.3 implementation.

Specifications

MyFaces implements Java Specification Request 127 . Each major release of MyFaces is certified against the Sun TCK to ensure compliance.

The JSF 1.1 specification was issued on 11 March 2004.
