I'm using:

        Java SDK 1.4.2_03, 
        Java J2EE 1.4
        jakarta-taglibs-standard-1.0.5
        jakarta-tomcat-4.1.30

I've had no trouble using the core, sql, and fmt tags in my JSPs.
***All I did was to drop jstl.jar and standard.jar into my WEB-INF
directory and add the proper directives to the JSPs***

for example:
   <%@ taglib uri="http://java.sun.com/jstl/core"; prefix="c" %>
   <%@ taglib uri="http://java.sun.com/jstl/fmt"; prefix="fmt" %>
   <%@ taglib uri="http://java.sun.com/jstl/sql"; prefix="sql" %>

I do/did not need to add anything at all the app's web.xml.

I'm working on a quite large and controlled application, so the
fewer changes I make the better.  Its very cool that I could
use tags just by adding the jars to the lib dir....

The problem:

Now, I have occasion to want to use c-rt as well. (Especially
because its too burdensome to pass data back and forth between
the tags and java kingdoms thru the page context for simple
string manipulations..)

As soon as I try to use c-rt, problems begin..
I cannot just add:
   <%@ taglib uri="http://java.sun.com/jstl/core-rt"; prefix="c-rt" %>
because the uri is not found on page compile.  If I add a direct
reference for this URI to my web.xml, then this URI is Ok.  i.e.

  <taglib>
    <taglib-uri>http://java.sun.com/jstl/core-rt</taglib-uri>
    <taglib-location>/WEB-INF/lib/standard.jar</taglib-location>
  </taglib>

fixes the c-rt issue, but now --none-- of the sql tag impls can be
found... even if I add another direct reference for them to the
web.xml, for example, adding:

  <taglib>
    <taglib-uri>http://java.sun.com/jstl/sql</taglib-uri>
    <taglib-location>/WEB-INF/lib/standard.jar</taglib-location>
  </taglib>

to the web.xml does not help.

For now I give up using c-rt, but...

Seems very strange, any ideas?  Does this seem a familiar problem?
