compile time error, cannot find symbol

If anyone can help me with this it will be greatly appreciated. when i compile the following code i keep getting the symbol not found error

public void doThinking()

{

//here i load and restore the saved network

NeuralNetLoader netLoader = new NeuralNetLoader ("VehicleNeuralNet.snet");

NeuralNet cmceNet = netLoader.getNeuralNet();

//here i remove all the saved nets' inputs and attach a memory synapse

Layer input = cmceNet.getInputLayer();

input.removeAllInputs();

DirectSynapse memInp = new DirectSynapse();

input.addInputSynapse(memInp);

//do the same thing for the outputs

Layer output = cmceNet.getOutputLayer();

output.removeAllOutputs();

DirectSynapse memOut = new DirectSynapse();

output.addOutputSynapse(memOut);

//start the net

cmceNet.start();

for (int i=0; i < 6; ++i)

{

// Prepare the next input pattern

Pattern inPattern = new Pattern(idea);

inPattern.setCount(1);

// Interrogate the net

memInp.fwdPut(inPattern);

// Read the output pattern and print out it

Pattern outPattern = memOut.fwdGet();

System.out.println("Output#"+(i+1)+" = "+outPattern.getArray()[0]);

}

cmceNet.stop();

the error is being generated by the methods attempt to create a new Pattern object. i have checked the pattern class file and it is were it should be in joone engine jar, I have attempted to import it directly and via engine.* as can be seen here

import java.lang.Runnable;

import java.util.Random;

import java.text.*;

import java.io.*;

import java.io.Serializable;

import org.joone.engine.*;

import org.joone.engine.Pattern;

import org.joone.engine.Monitor;

import org.joone.net.NeuralNetLoader;

import org.joone.net.NeuralNet;

import org.joone.engine.DirectSynapse;

import org.joone.engine.Layer;

import org.joone.log.ILogger;

import org.joone.log.LoggerFactory;

import org.joone.util.UnNormalizerOutputPlugIn;

other classes that use these import statement work fine and i am stuck. Please help.
