OnTop Reasoner Not Starting

[Nilabhra Patra]

Hi,

I am following the OnTop Tutorial at https://ontop-vkg.org/tutorial/basic/university-1.html#ontology-classes-and-properties.

I am unable to start the OnTop Reasoner. After selecting the Ontop Reasoner from the Reasoner list and clicking 'Start Reasoner', it does nothing. Hence I can not use the OnTop SPARQL too.

Let me know on what to do here.

Thanks,

Nilabhra

Hello Nilabhra,

Can you share the logs of Protege?

Hi Julien,

I was able to solve this.

I was getting NullPointerException. Had to reset the Preferences and restart Protege.

Thanks,
