------------------------------------

David,

WRT to 2 I can start another developer forum thread (I seem to remember comment on this requirement in a developer forum thread a year or more ago). However it you look at the text in this JIRA it says:

"Either the same ESB Service, or different service with access to the StatefulKnowledgeSession, can then receive messages / events and insert them into the StatefulKnowledgeSession. "

> To better support CEP, an ESB Rule Service should 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 service with access to the StatefulKnowledgeSession, can then receive messages / events and insert them into the StatefulKnowledgeSession. 
> FireUntil Halt provides two important benefits to a CEP application. First it provides more timely rules firing. Even more important, it support the case where the absence of incoming events should cause rules to fire.
