[rules-users] How can generated facts/events be published?

[Wolfgang Laun]

The usual method:
You establish a TopicPublisher as a global declared in your .drl file.
   global TopicPublisher topicPublisher
You must set this from Java code using
   TopicPublisher topicPublisher = ...;
   statefulKnowledgeSession.setGlobal( "publisher", topicPublisher )
and then you use it in any RHS code.

Of course, a TopicPublisher could also be (field of) some fact,
but this shouldn't be necessary for such a central service.
