instantiating package manager
===

I am getting the following errors when I try to retrieve a something from the server. I am trying to communicate with the Server side with GWT. but it has been giving me errors all week. this is the latest one. I am stumped as to how to fix. Any help would be appreciated. 

here is PredictClientServlet.java

    
    public class PredictClientServlet extends RemoteServiceServlet implements PredictClient
    {
 
        public List<ArrayList<Double>> myMethod(String[] keywords, int numOfPredictions, List<Data> input)
	    {
		
		TS ts =new TS( input );
		// Create the predictor
		Predictor predictor = new Predictor();

		//Set the number of predictions 
		predictor.setNumPredictions(3);
		try
		{
			//Set the data
			predictor.setTargetData(ts);

			//Add the filters (now this is not doing any difference)
			predictor.addFilter("filterA");
			predictor.addFilter("filterB");
			predictor.predict();
		}
		catch (Exception e)
		{

		}
		List<Predictions> allPredictions = predictor.getPredictions();
		List<ArrayList<Double>> ret =new ArrayList<ArrayList<Double>>();
		for (Predictions pred: allPredictions) 
		{
			System.out.printf("Predictor %s %n",pred.getName());
			int c = 1;
			ArrayList<Double> temp =new ArrayList<Double>();
			for (Prediction p: pred.getPredictions()) 
			{
				System.out.printf("\t Prediction: %d Value: %f [%f,%f] %n",c,(p).getValue(),p.getLowConfidence(),p.getHighConfidence());
				temp.add(p.getValue());
				c++;
			}
			ret.add( temp );
		}

		return ret;
	}

	
here is my PredictClient.java

    public class Predict implements EntryPoint
    {

	@Override
	public void onModuleLoad() 
	{
		final PredictClientAsync predictService = GWT.create(PredictClient.class);


		AsyncCallback<List<ArrayList<Double>>> callback =new AsyncCallback<List<ArrayList<Double>>>()  
				{

			public void onFailure(Throwable caught)
			{
				caught.printStackTrace();
				System.out.println("Error! " + caught.getCause()   );// do some UI stuff to show failure
			}

			@Override
			public void onSuccess( List<ArrayList<Double>> result ) 
			{
				//Global.data = result;
				Global.c.clear();
				Global.c =new Chart();	
				Global.c.onModuleLoad();
			} };
			predictService.myMethod(null,3, Global.predata,callback ); 

	}


and Here is my dreaded errors:
