Hi Jeff, Let me try to understand this architecture from a higher level point of view, not ESB or Drools specific: * the order service executes the business tasks it needs to execute, and also publishes events. * the customer service executes the business tasks it needs to execute, and also publishes events. * the delivery service is interested in the events published by the order service and by the customer service and uses them to take business decisions. Is that the case? Can you plz comment on my point of view above? Thanks, Edson View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4240104#...
