I got bit by this one too. After spending quite a while poring through the Java source, here's a solution:

TransformFactory factory = TransformerFactory.newInstance();
factory.setAttribute('indent-number', new Integer(4));

This works with Java 1.5 but (sigh) the setAttribute() call causes an IllegalArgumentException in 1.4. So wrap the setAttribute() in a try/catch and throw away the IllegalArgumentException..."
