Save an load a DBN in hugin format

[rcabanasdepaz]

It seems that the code for saving a DBN in hugin format is not correct. In the following code,
I save a DBN and then I try to load it.

    //Load the data stream
    String path = "datasets/simulated/";
    String filename = path+"BCC_month0.arff";
    DataStream<DynamicDataInstance> data =
            DynamicDataStreamLoader.loadFromFile(filename);

    //Learn the dynamic model
    DynamicModel model =
            new HiddenMarkovModel(data.getAttributes());
    model.updateModel(data);

    // Print the BN and save it
    DynamicBayesianNetwork dbn = model.getModel();
    System.out.println(dbn);
    DynamicBayesianNetworkWriter
            .save(dbn, "networks/simulated/BCCDBN.dbn");

    DynamicBayesianNetworkWriterToHugin
            .save(dbn, "networks/simulated/BCCDBN.oobn");

    //Load the DBN
    DBNLoaderFromHugin.loadFromFile("networks/simulated/BCCDBN.oobn");

I get the following exception:

Parse error in line 1: expected `class' keyword
Exception in thread "main" COM.hugin.HAPI.ExceptionParse: An error occurred during parsing. If a parse error handling function was specified, it will have been called with a description of the error and its location in the source.
