Has anyone any idea, where to look for the error?

Answer 1

If you take a careful look at the error message, you'll notice that it's actually trying to process the JPEG file, which will of course fail. By default when invoked this way, the xslt task will try to transform all files it finds in the specified directory. You can add add an attribute like includes="*.xml" to tell it to process *.xml files only.
