Error in rapidminer.init()

Question

I'm new in integrating Rapid miner in Java applications and currently i'm having an exception in the rapidminer.init(). As far as i can understand its because od the repositories. But i don't know what to do. I did some research but i still cant resolve my problem. The exception is:

My code is very simple:

public RapidMinnerInteraction()
    {

             RapidMinerCommandLine.init();

              Process process = null;
            try {
                process = new Process(new File("NeuralNetwork/NeuralNetworkProcess.rmp"));
                try {
                    process.run();
                } catch (OperatorException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            } catch (IOException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            } catch (XMLException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }




    }

Any help would be awesome

Kind regards

From the exception it looks like you missed to add at least the vldocking.jar file to your classpath, possibly others are missing too.
