You can't use variables in property paths, so ?p1/?p2 isn't a legal property path. You shouldn't be able to parse it as a legal query. As an alternative (which I'm not sure will work, but it might be worth investigating), you could use a ParameterizedSparqlString with "?s ?p1/?p2 ?o" as

I don't know if startRequest was called or not, since I didn't write any log there, other than capturing the start time. This is my code (the graphDataset is the subclass code I mentioned): UpdateRequest request = UpdateFactory.read(stream, Syntax.syntaxARQ); GraphStore graphStore =

In which the second argument is the class and not the model as in your code. It looks like you did mostly copy and paste without understanding the code. In your case the model is ALWAYS null, do you understand that? > I have read it here: > http://tutorial-academy.com/category/java/ > > He used

I have read it here: http://tutorial-academy.com/category/java/ He used null argument in the main() method: public static void main(String[] args) { // create OntModel OntModel model = ModelFactory.createOntologyModel(); // read camera ontology readOntology( "./ontology/camera.owl", model ); //

Re: Exception in the code

I don't get it. Where did you saw this in the Jena tutorial? And do you understand that when you call in your main() read(str, null); that the second argument is always null, thus, the code will never go into the if-clause? > The read() method is given below: I used null reference after

Re: Exception in the code

Andy already told you correctly that you call read(str, null) thus the second argument is null. Moreover, you did not show the read() method but only readOntology(), thus, nobody knows what's going inside the read() method. But obviously, some object is null and you call a method on that. I
