Or you could use Saxon (http://saxon.sourceforge.net) that already supports
JDOM source trees (but converts them into its internal representation).

When you say "objects", are you talking about JDOM objects or application
objects which are converted to streams using some XML-Object mapping tool?

Are you using Templates (i.e. precompiled stylesheets reusable for many
The combination JDOMSource -> Saxon (with Templates) -> JDOMResult usually
leads to very acceptable performances.
