You install the JSF Reference Implementation as follows:
Download the JSF reference implementation from the Sun JavaServer Faces website: http://java.sun.com/javaee/javaserverfaces/
Unzip the downloaded file into a folder. This folder contains the required library files:
commons-beanutils.jar
commons-collections.jar
commons-digester.jar

The JSF reference implementation requires an additional jar file:

You can download it from the Apache Jakarta Project website: http://jakarta.apache.org/.
Unzip the downloaded file to obtain the folder "jakarta-taglibs\standard\lib", and copy the jstl.jar file to the JSF reference implementation lib folder.
Define a "JSF_LIB" variable in the PowerDesigner "General Options" window, Variables tab to indicate the JSF reference implementation lib folder path.
