Answer 1

If some one having this problem,

Please re-check whether you set the weka.jar file path in to your web service. Specially if you add the weka.jar file to the build path of your web service project it doesn't add to the hosting web service only for the application environment.

Make sure to add the file in to WebContent -> WEB-INF -> lib -> weka.jar

Then It will works fine.
