[SOLVED] Using Jena with Pellet; NoClassDefFoundError Exception

Using Jena with Pellet; NoClassDefFoundError Exception

I'm trying to use Jena 2.12.1 with Pellet; I downloaded the latest Apache Jena library from their site Jena 2.12.1.

First, I downloaded Pellet 2.3.1 and imported the JENA libraries. Unfortunately, org.mindswap.pellet.jena.PelletReasonerFactory couldn't be resolved, and thus, I couldn't instantiate a reasoner.

Then, I downloaded multiple versions the jar file pellet-jena-2.3.2 (tried 2.3.1 and 2.3.0). This resolved org.mindswap.pellet.jena.PelletReasonerFactory. However it caused the exception:

Exception in thread "main" java.lang.NoClassDefFoundError: org/mindswap/pellet/utils/progress/ProgressMonitor

My code:

import org.mindswap.pellet.jena.PelletReasonerFactory;
import com.hp.hpl.jena.rdf.model.InfModel;
import com.hp.hpl.jena.rdf.model.Model;
import com.hp.hpl.jena.rdf.model.ModelFactory;
import com.hp.hpl.jena.reasoner.Reasoner;

public class Test {
public static void main (String [] args)
{
    Reasoner reasoner = PelletReasonerFactory.theInstance().create();

    // create an empty model
    Model emptyModel = ModelFactory.createDefaultModel( );

    // create an inferencing model using Pellet reasoner
    InfModel model = ModelFactory.createInfModel( reasoner, emptyModel );
}   
}

What is the problem? is there a better way to use jena 2.12.1 with Pellet (any version)?

Solution

Using pellet-2.3.0 (Aug 22, 2011) including JENA compatible librairies instead of pellet-2.3.1 has solved the problem.
