just put all of JSF related .jar file to the web-inf\lib folder, then you can use JSF in your application
Thanks for your help.
Now it seems to recognize JSF, but it still encounters an error:
org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jsf/html cannot be resolved in either web.xml or the jar files deployed with this application
i have a folder with following content (Folders with capital letters)
--LIB (contains all jars from the reference impl)
