Using JSF and JSTL With Web Applications

http://docs.oracle.com/cd/E24329_01/web.1211/e21049/configurejsfandjtsl.htm
 


 Create new JSF2 test project using Eclipse OEPE


Deploy JSF project to WLS
Run CAT
WLS must not be in Production mode - disable in config.xml 

  <production-mode-enabled>false</production-mode-enabled>

Required libs for JSF 1.2 
 JSF 1.2 requires java 1.5 or later, JSP 2.1, JSTL 1.2 and a Java Servlet 2.5 implementation. http://myfaces.apache.org/core12/index.html 

Deploy JSF 1.2 shared libraries for WLS  ( already contains filtering classloader in descriptor)
