How to use com.intersys.gateway.Service

I am trying to work with Java Selenium through Cache  my java programme works fine but I would like to pass parameters to the jar file form my Ensemble production. I followed this Tutorial here, For starters I wanted to copy it as it is and run that as an example but the (Stateless Service Mode Example) is not working within my eclipse environment with errors on the com.intersys. complaining about the service class. If anyone out there has had experience on this please advice all I need to do is be able to invoke my jar file within Cache(In general want to call my  java programme  within Cache and pass some parameters)
