How do I tranform the document using SAX-- i.e., how do I change this
line?
transformer.transform(new DOMSource(document), new StreamResult(out));

Yes, but your time is probably wasted elsewhere.
transformer = tFactory.newTransformer(new
StreamSource(getClass().getResourceAsStream(xsl)));
transformer.transform(new DOMSource(document), new
StreamResult(out));
^^^^^^^^^^^^^^^^
Use a profiler to check where your program wastes time:
- DB access or whereever you get your raw data
- DOM construction
- transformation
If it is the latter, check your XSL for inefficient constructs.
If it is DOM construction, use SAX. Also DOM uses a lot of memory,
which may be a problem in itself (more GC).
