Java EE (Java Enterprise Edition) General Discussion

Hi,
Just started evaluating JSF for our portal needs. I have this problem when I try to reach the jsp (UserSearch.jsp: provides a form to search for users.) that used JSF tags:
org.apache.jasper.JasperException: This absolute uri (http://java.sun.com/jstl/fmt) cannot be resolved in either web.xml or the jar files deployed with this application
at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:105)
at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:430)
at org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:154)
at org.apache.jasper.compiler.TagLibraryInfoImpl.(TagLibraryInfoImpl.java:159)

If i take off faces-config.xml from the war, then I am getting to the jsp page i.e. search page, but when I hit the submit button, as understood, its not able to find the action associated with action-ref attribute (UserBean.searchAction) (as there is no faces-config.xml). If I include faces-config.xml in web-inf library when building war, then the form itself is giving me the above error.

here I am giving my faces-config.xml

<?xml version="1.0"?>
