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.
Transformer objects may be reused, but they may not be used simultaneously by
multiple threads. (JAXP 1.1 spec.)
So, without a digression into threading in servlet containers and static
fields, you'll be much better off to store Templates objects in a HashMap and
access them as necessary. (Templates objects are safe for concurrent access
from multiple threads, or at least JAXP requires that.)
