Protege Stanford JessTab error

im trying to explore n getting familiar with JessRules. i have installed jessrules ver 7 engine into protege 3.4.8.

first im creating person class without problem:

Jess> (defclass Person (is-a :THING)
      (slot name (type string))
      (slot age (type integer))) <enter>
TRUE

then im creating individual:

(make-instance john of Person (name "John") (age 20)) <enter>

then i got following response:

<Java-Object:edu.stanford.smi.protegex.owl.model.impl.DefaultOWLIndividual>

in tutorial should be:

<External-Address:SimpleInstance>

but the instance is successfully created. but when i do mapclass and facts command, some part in instance facts output will contains error too:

(MAIN::object (is-a Person) (is-a-name "Person") 
(OBJECT <Java-Object:edu.stanford.smi.protegex.owl.model.impl.DefaultOWLIndividual>)
(rdfs:label ) (owl:versionInfo ) (rdfs:comment ) (rdfs:member ) 
(:NAME "john") (rdfs:isDefinedBy ) (rdfs:seeAlso ) (owl:differentFrom ) 
(owl:sameAs ) (rdf:value ) (protege:inferredType ) 
(rdf:type <Java-Object:edu.stanford.smi.protegex.owl.model.impl.DefaultOWLNamedClass>) 
(name "John") (age 20))

im not sure about this error. i have already try to google and didnt find any clue. thank you in advance for your help.

There are no "errors" here; it's just that JessTab and Protege have evolved over the years since your tutorial was written, and the names of some classes have changed.
