Two other items we should discuss. The first is related to a discussion earlier in this topic on multiple services using the same StatefulKnowledgeSession, and that is the use of fireUntilHalt. We want an ESB Service to be able to create the KnowledgeBase, StatefulKnowledgeSession, etc, and then execute fireUntilHalt. This will cause the thread to block, and the rules engine will continue to process (in a separate thread). Either the same ESB Service, or different services (this is the relationship to the discussion earlier in the topic) can then receive messages / events and insert them into the working memory. However the absence of incoming event may still cause rules to fire. Second item is that the BusinessRulesProcessor should allow for configuration of a log file for audit logging. This audit log can then be read by the JBTools Drools Audit viewer. Which is very convenient for debugging.
