Cant get openllet running on Fuseki

yesterday i was trying to get Pellet and/or Openllet to run on my Fuseki Server.

Im am doing Requests over the Web-Interface. Without reasoners its working fine.

This is my configuration:

Error-Log in the Tomcat Directory:

I had been copying the Openllet Jar-Files (openllet-query-2.6.5.jar and things) everywhere, but no chance. Btw is this the right action anyway?!

In my Apache Jena project (and Snarp Sparql Protege Plugin) i got Openllet to run and it gets me the right results.

I got a few rules that are all of this type

                                                            ]
                                       ]
                                     )
                       ]
                     ) ;
  rdf:type owl:Class ;
  rdfs:subClassOf [ rdf:type owl:Restriction ;
                    owl:onProperty food:violatesRestriction ;
                    owl:hasValue food:kosherReligious
                  ]
] .

"Not kosher if there is pork in a recipe or meat in combination with a dairy product."

The reasoning is horrible slow (8 seconds on a 25000 triple database). If i extract the model before it runs fast but the extraction of the model takes 3 minutes.

I just want to have a way where the user can query recipes with the inferences of a reasoner in a reasonable time (< 2 seconds) :(

Are there any more (better?) reasoners who can work with blank nodes (Hermit cant...) ??

My questions are:

1. How can i get Fuseki to run with Pellet/Openllet
2. Reasoner alternatives?
3. Is there a better way to infer rules like the one above?
4. Am i completely wrong and do i have to let the reasoner to be run only one time at the start of the program and not for every query?

Best regards ;)

Instead of Openllet i tried the OWLMicroFBRuleReasoner, it worked! And its fast!
