Data Science & Machine Learning

Hi, I am running into issue to execute the sample data mining program to build a classification model, Naive Bayes. I loaded the necessary patches. I have same version of odmapi.jar both in db and jdev.
Oracle DB version : 9.2.0.4.0; ODM : 9.2.0.4.3;JDeveloper : 9.0.4.0.0
Pls. help to resolve the issue. Thanks.
