You don't need to train word-by-word, you can just use the
ITrainableClassifier.teachMatch(String) and teachNonMatch(String) methods
(See
<http://classifier4j.sourceforge.net/apidocs/net/sf/classifier4J/ITrainable.
html#teachMatch(java.lang.String)>). If you want to use non-default
categories then there are version of teachMatch & teachNonMatch that take a
category, too.

Have you looked at the code for the demos, in particular
net.sf.classifier4J.demo.Trainer
(<http://cvs.sourceforge.net/viewcvs.py/classifier4j/Classifier4J-Optional/s
rc/java/net/sf/classifier4J/demo/Trainer.java?view=markup>)?

Let me know if that doesn't make things clearer.
