I have just starting using JSF. I made a simple web application using Apache tomcat. I made a index.jsp as the welcome page and configured it in the web.xml.
It works fine till here . Then since i wanted to introduce JSF in the web application i added jsf-api.jar in the lib folder of the web application . Till here it worked fine , but as soon as i introduced jsf-impl.jar in the lib folder it gave a '404 Error' .
I would appreciate if any one can tell me why by just introducing jsf-impl.jar in the lib folder would i get this error.
