A couple of more questions,
I am calling my rules engine from a service and into the session i am
inserting the business object.
In my service class, I have a few helper functions, which I need to call
from my drl file.
How can I do that ?
Thanks

Your rule file will have:
global java.lang.String recipients
global java.lang.String to
global java.lang.String cc
