In my web application I need to use Saxon TransformerFactory to use XSLT 2.0 but I can't use setProperty method because I haven't this right on the web server and there is a Security Manager.

So i have read that it's possible to do this:

Use the Services API (as detailed in the JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.transform.TransformerFactory in jars available to the runtime.

I found this file in WEB-INF/lib/saxon9.jar but when I istantiate a TransformerFactory is always selected default factory and not saxon factory.

How can I select Saxon Transformer Factory?

Thanks
