Hello Andrew, You're registering the CatalogResolver with a TransformerFactory. It looks like Xalan does not propagate this resolver to the parser instances it creates (and I'm not sure that it should). You could try passing in a SAXSource instead and explicitly set the entity resolver on the XMLReader to be the CatalogResolver.
Thanks.
