Different result in Protege 4.3 and result in jena in Eclipse

In Protégé 4.3 I have results with ObjectProperties (exactly as I need). But I need to implement it in my project so I use Jena in Eclipse and the result is different. How can I get object with ObjectProperties in Jena?

Solution

  • I have no prob to write down some code as answer, but its hard to write it clear and easy to understand.

    One more time: I ask how to get in jena sparql result like this object + object property + subject(s) [ C2-C4].

    And the result is (this sample with 3 subjects)
