Cant get openllet running on Fuseki - jena

Question

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:
#prefix : <http://base/#> .
#prefix tdb: <http://jena.hpl.hp.com/2008/tdb#> .
#prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
#prefix ja: <http://jena.hpl.hp.com/2005/11/Assembler#> .
#prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
#prefix fuseki: <http://jena.apache.org/fuseki#> .

Error-Log in the Tomcat Directory:
ERROR Exception in initialization: the class 'openllet.jena.PelletReasonerFactory' required by the object 7c374328cddba9fa8091dcebd77a7598 [ja:reasoner of file:///C:/etc/fuseki/configuration/FOOT.ttl#model_inf] could not be loaded
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 ;
owl:unionOf ( [ owl:intersectionOf ( [ rdf:type owl:Restriction ;
owl:onProperty food:hasIngredient ;
owl:someValuesFrom food:Dairy
]
[ rdf:type owl:Restriction ;
owl:onProperty food:hasIngredient ;
owl:someValuesFrom [ rdf:type owl:Restriction ;
owl:onProperty food:hasFood ;
owl:someValuesFrom food:Meat
]
]
) ;
rdf:type owl:Class
]
[ rdf:type owl:Restriction ;
owl:onProperty food:hasIngredient ;
owl:someValuesFrom [ rdf:type owl:Restriction ;
owl:onProperty food:hasFood ;
owl:someValuesFrom food:Pork
]
]
)
]
) ;
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:
How can i get Fuseki to run with Pellet/Openllet
Reasoner alternatives?
Is there a better way to infer rules like the one above?
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 ;)

Answer 1

Instead of Openllet i tried the OWLMicroFBRuleReasoner, it worked! And its fast!
<#model_inf> a ja:InfModel ;
ja:baseModel <#graph> ;
ja:reasoner [
ja:reasonerURL <http://jena.hpl.hp.com/2003/OWLMicroFBRuleReasoner>
] .
