I've done exactly that with great success.  On application start, all
available xsl templates (as listed in XML resource file) are created as
Transformer objects and stored in a hashmap with the filename as the key.
Then, whenever a transformer is needed on request, simply grab it from the
hashmap and use it.  If it's not already there, you can try to create it -
then store it in the hashmap for later requests.
A Transformer cache, if you will...

Performance suddenly became a non-issue when we did this.... but then, we
were doing 5 to 20 tramforms per request, so it was terribly slow to begin
