Use jstl core as a local resource

I would like to download those libraries and import them from the computer to the application.

<%@ taglib uri="http://ift.tt/QfKAz6" prefix="c" %>
<%@ taglib uri="http://ift.tt/1bRkrVx" prefix="fmt" %>
<%@ taglib uri="http://ift.tt/1lpNXqs" prefix="fn" %>

How can I do that ?

If you want to know why, the server can't reach the Internet, so it won't get the libraries. I know how to do that with JQuery, but no answer found for the taglibs ...

Thank you
