Pellet Reasoner Error

[Jibbi]

Hi everyone,

I’m trying to run Example8 from OWLAPI documentation. I’m using Eclipse
IDE and I have included these (pellet.jar, aterm-java-x.x.jar, xsdlib.jar
and relaxngDatatype.jar) jar files from pellet-1.5.2. Still It’s not
working and I’m getting below mentioned exceptions.
Any suggestion?


Loaded http://www.co-ode.org/ontologies/pizza/pizza.owl
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/commons/logging/LogFactory
        at org.mindswap.pellet.owlapi.Reasoner.<clinit>(Reasoner.java:80)
        at java.lang.Class.forName0(Native Method)
        at java.lang.Class.forName(Unknown Source)
        at community.ontology.Reasoning.createReasoner(Reasoning.java:134)
        at community.ontology.Reasoning.main(Reasoning.java:37)



Thanks in Advance
Best regards,

The "java.lang.NoClassDefFoundError" indicates that there is a JAR file
missing from your classpath (the commons-logging JAR).

Also, the OWL API has a separate support mailing list that you can post
questions to:

http://owlapi.sourceforge.net/support.html
