This sounds like a question for the Pellet list. Jena has no specific support for SWRL rules. Pellet does support the Jena Reasoner interface so you should be able to create an InfModel (or OntModel) over your data using PelletReasonerFactory [1]. If that doesn't work for SWRL rules then you may need some Pellet-specific code. As a piece of debugging advice, I would start by declaring some simple relationship in pure OWL (no SWRL) and check that your set up correctly sees those inferences. If that works but SWRL doesn't work then you have something more specific to ask the Pellet folks. Dave [1] http://clarkparsia.com/pellet/faq/using-pellet-in-jena/
