Persistence on Java CI-Bayes object

Question

Has anyone ever persisted a training set for CI-Bayes? I have sample code from this site: http://www.theserverside.com/news/thread.tss?thread%5Fid=49773

here is the code:

FisherClassifier fc=new FisherClassifierImpl();
fc.train("The quick brown fox jumps over the lazy dog's tail","good");
fc.train("Make money fast!", "bad"); 
String classification=fc.getClassification("money", "unknown"); // should be "bad"

so I need to be able to store the training set in a local file.

Has anyone ever done this before?
