A few quick questions:

  1. Where is your JSF library located?

  2. I think you meant more after:In my IDE also I can see the which leads into.

  3. Eclipse is usually pretty good at being able to find your tag libraries. Is it complaining about the use of these libraries in your jsp editor page?

Let us know some more info about your setup first.

I'll throw out the obvious solution: You've lost the reference to your JSF jar(jsf-impl.jar). Including it in your Tomcat lib folder should fix it.
