Hi Esteban, thanks for the reply. I created the "Service Layer" in my project containing the interfaces. Then I packaged them into a jar file and uploaded to Guvnor. Guvnor put it into a model and then I promote it to Global. However, when I write a rule, either business rule or technical rule in Guvnor, it seems like the starting point is always "When". I didn't find a place to put the "global com.some.package.EmailService emailService" declaration before the rule. I tried to use EmailService, which is the model name in the Global area directly in RHS of my rule but Guvnor threw out error on that. Could you please indicate how this can be done in Guvnor?
Thanks and best regards Yu -- View this message in context: http://drools.46999.n3.nabble.com/Dummy-question-from-a-new-comer-tp3248102p3251581.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
