Can you tell me where is located the " OWL +SWRL-> Jess " button?
I have the same version of Protege and also have Jess engine installed.

rdfs:label is an RDF entity not an OWL entity so is not supported by
SWRL. I plan to have a RDF built-in library soon to support the use of
RDF entities queries.
