The message is presumably coming from the call on
TransformerFactory.newInstance().

I don't know specifically why you're getting it, but it looks to me as if,
for some reason, the TransformerFactory that you've successfully loaded from
the classpath, is trying to load a TransformerFactory implementation that
isn't loadable. So there's something missing from your classpath.

As for the rest of your logic, if you're controlling the transformation from
Java, I wouldn't normally use "getAssociatedStylesheet" which relies on
identifying the stylesheet from the <?xml-stylesheet?> processing
instruction in the source XML document; I would identify the stylesheet and
the source document separately from the Java code. But of course that
depends on your application requiremetns. If you do use
getAssociatedStylesheet you'll probably need to use setSystemId() so that
the system knows the URI of the source document, so it can resolve any
relative URI referring to the stylesheet.
