Pellet + Jena

[Halim Noor]

Hello, I'm running Pellet with Jena as the following:

public static void main(String[] args) {
       
        String inputFileName = "onto.ttl";

        FileInputStream inputStream = null;
       
        try {
            inputStream = new FileInputStream(inputFileName);
        } catch (FileNotFoundException e) {
            System.err.println("'" + inputFileName
                    + "' is an invalid input file.");
            return;
        }
              
        OntModel model = null;

        model = ModelFactory.createOntologyModel(PelletReasonerFactory.THE_SPEC);
       
        model.read(inputStream, null, inputFileFormat);

        ...
}

But I'm getting error as follows

Exception in thread "main" java.lang.NoClassDefFoundError: aterm/ATerm
    at org.mindswap.pellet.jena.PelletReasoner.bind(PelletReasoner.java:95)

I'm using Pellet 2.3.1. Please help.

Thank you.

Hello,

you are missing the aterm-java-1.6 library in your classpath. The jar-file can be found in the lib-folder of your pellet 2.3.1 distribution.
