[2017-12-08 15:53:16] Server INFO Started 2017/12/08 15:53:16 CST on
port 3030
No similar problem found on stackoverflow or anywhere else.
I have also tried two RDF formats, N-Triples and Turtle. It doesn't work as
well.
I'm so confused about that TDB with inference doesn't work while the case
without infmodel is ok.
Actually, I tried on the example given by jfmunozf at
https://github.com/jfmunozf/Jena-Fuseki-Reasoner-Inference. I use the
tdbloader tool to convert the data.ttl into TDB. The fuseki server works
well with Infmodel integrated.
