"Couldnot read from XML stream"

happydust

I am trying to read this mod file and load the model from it. I keep getting those error messages telling me it cant read XML file,and telling me what jar files were missing.
so i added all the Jar it asked for, and finally i reached the point there is no further explanation and i couldnt go any further. Does anybody know what is happening?here is the final error message.

Could not read file 'D:\Study\workspace\org.reqmon.rapidminer.plugin\resources\xml\model.mod': Cannot read from XML stream, wrong format: com.rapidminer.operator.ContainerModel : com.rapidminer.operator.ContainerModel.

and here is my code -- I basically copied this from somewhere, and am not sure if that is the correct way to do it.

public class ReadModelTest {

	//private OperatorChain wvtoolOperator;
	//private Operator modelApplier;
	private TreeModel model;
	/*
	 * This test runs the DBDecisionTree.xml process which runs
	 * a Decision Tree learning model against the RapidMiner golf
	 * data.  It tests that the service object returns a proper
	 * IOContainer containing the expected performance vector and
	 * model classes.  It also iterates through the resulting objects
	 * and tests the RapidMiner API.
	 */
@Test
//private OperatorDescription OperatorDescription;
   public void ReadModelTest()throws IOException, OperatorCreationException, OperatorException{
	   

	File modelFile=new File("resources\\xml\\model.mod\\");


	RapidMiner.init();

	Operator modelLoader = OperatorService.createOperator("ModelLoader");

	modelLoader.setParameter(ModelLoader.PARAMETER_MODEL_FILE, modelFile.getAbsolutePath());
	IOContainer container = modelLoader.apply(new IOContainer());
	model = container.get(TreeModel.class);
	assertNotNull(model);

    Tree root = model.getRoot();
    assertNotNull(root);
    
   
    System.out.println("lable is"+root.getLabel());// try to show the root label
	//return model;
    }
   

   public static void main(String args[]) throws Exception {

		// Create a text classifier  
		ReadModelTest tr = new ReadModelTest();

		// Call the classifier with texts




	}


	}

I'd reallly appreciate if someone can help me:)

Hi,
did you check if your model file simply exists? If yes, does it load, if you try using the rapid miner api?
