If you dump a report like this please make your best effort to make it something easily reproducible by taking at least the examples of the distrib or to attach the sample files. Do not assume the reader familiar with the third party package you are using. This was all but necessary here. Your problem is probably due to a classloader problem since jaxp is in the main classloader while your provider is in child classloader, child classloader that is not the context classloader thus the fallback to the factory finder classloader which is...the main classloader. I'm degrading this to enhancement and add it as a duplicate of 6606. In your case your taskdef of xslt is useless since it is a mere duplication of the Ant xslt core task. It has been removed in fop 2.0.4 *** This bug has been marked as a duplicate of 6606 ***
