java.lang.ClassNotFoundException: org.apache.jena.rdf.model.ModelFactory

[Karim Mont]

Hi,

I am trying to do the first example of the jena rdf tutorial.
It seems that the class is not found even the maven build was successful.

Here is my class code:

package com.mycompany.app;

import org.apache.jena.rdf.model.*;
import org.apache.jena.vocabulary.*;

public class RdfWriter {
    static String personURI    = "http://somewhere/JohnSmith";;
    static String fullName     = "John Smith";

public static void main(String[] args) {
//        // create an empty model
        Model model = ModelFactory.createDefaultModel();
//       // create the resource
//       Resource johnSmith = model.createResource(personURI);
//      // add the property
//      johnSmith.addProperty(VCARD.FN, fullName);
System.out.println("this is rdf writer");
}

}

I am running it like this:

java -cp target/my-app-1.0-SNAPSHOT.jar com.mycompany.app.RdfWriter

And here is my pom file:

<project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="

Here is the full error that I get:
