HI,

Thank you for your help,
I use the same method (addProperty) on an ObjectProperty object, like the
following :

ObjectProperty op =
model.createObjectProperty(mypropURI).addProperty(RDF.type,
OWL2.ReflexiveProperty));

regards

Reflexive is an OWL 2 feature and Jena's built-in helper methods only 
support OWL 1. However it is easy to create the requisite RDF syntax for 
this:

     Property myprop = model.createResource(mypropURI)
                         .addProperty(RDF.type, OWL2.ReflexiveProperty);
