[rules-users] How to execute a Process API result?

[Mauricio Salatino]

Ok, so you need to start using the Drools 5 APIs.
Please take a look at the Drools 5 documentation:
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-flow/html_single/index.html#d0e1375

In the section 3.2
Using a Process in Your Application
you will find the correct api's.
Greetings.
