First of all, you probably should use property names that begin with a
lowercase letter. It just might work beginning with a capital, but you
also may run into unexpected trouble.

Assuming you're using a standard Servlet 2.3 container, you might
consider using the "normalized" URI for each taglib (the value of the
"uri" property in the tld). This allows you to avoid having to store
the TLD separately from the taglib jar, and avoids the need to add the
taglib element to your web.xml. It still requires the taglib directive
in the JSP (using the normalized URI).
Also, as another posted pointed out, you're missing the "core" taglib
directive. Without that, your reference to the "c:out" tag would have
been untranslated (the html output would still contain "<c:out .../>".

Note that there's no need to do this. If the variable is already
available in request scope, there's no need to set it into another
variable in page scope.

If your property name was "totalPosts", instead of "TotalPosts", and you
had the correct taglib directive in your JSP, then this should have
worked.
