David,
Since the .jar file won't be within the web application at runtime, 
the .jar file can't be referred to directly.  The TLD file inside 
must expose a URI using the "uri" element and the .jsp file has to 
use that URI to find it (assuming I'm not misreading the specs and 
your original posting).  How is the .jsp referring to those tag 
libraries?

It almost sounds more like bug 129112.
