Using MOA command line

[D Razz]

Hi, 

I am trying to run  multilabel/ MEKA classifier through MOA in command line in window. I use this command (I want to predict all last 6 classes (attributes)) :

java -cp moa.jar;meka.jar;weka.jar -javaagent:sizeofag.jar moa.DoTask "EvaluateModel -m (LearnModel -l (multilabel.MEKAClassifier -l (meka.classifiers.multilabel.incremental.BRUpdateable)) -s (ArffFileStream -f C:\emotions-train.arff -c 6)) -s (ArffFileStream -f C:\emotions-test.arff -c 6)  -o C:\results.txt"

 I am however having some trouble, can anyone help me please with some ideas on how to tackle these problems? Would be much appreciated!

weka.classifiers.bayes.NaiveBayesUpdateable

It seems that this class is not found in the java classpath.

Cheers, Albert
