Tool Schemagen don't print the Properties and the individuals

Hello everyone, I want to create the Java class that corresponds to my
ontology .owl, for this i'm going use the tool schemagen.bat with Windows, but
in the java class there are only the Resource while the Property and the
Individuals not.
Any idea on how to solve the problem? here is the code entered in the prompt of
the programs with the goodrelations ontology for example:

c:\Program Files\Apache Software Foundation\apache-jena-2.11.2\bat>
schemagen.bat

java jena.schemagen -i
http://www.heppnetz.de/ontologies/goodrelations/v1.owl -n GoodRelations -a
http://purl.org/goodrelations/v1# -e OWL -o c:\Users\Utente\Desktop
--ontology

kind regards.
