I have a similar situation, and am kicking around JMS/MDBs.<br><br>I'm interested in the feedback you get on this question. <br><br><div class="gmail_quote">On Wed, Feb 11, 2009 at 8:45 PM, Dan Seaver <span dir="ltr"><<a href="mailto:dan.seaver@ge.com">dan.seaver@ge.com</a>></span> wrote:<br>

Is there any recommended "Best Practice" for instantiating and accessing a<br>
StatelfulKnowledgeSession in a J2EE environment?<br>
<br>
One use case for this type of session is it will act as a Complex Event<br>
Processor - taking in low-level events from all over the system and throwing<br>
complex events based on Fusion rules. The session is intended to be global<br>
in nature as ALL events will flow through this CEP processor.<br>
<br>
Another use case would be for long running processes or work-flows that<br>
interact with data streams.<br>
<br>
The 3 patterns I'm looking at are:<br>
- the Singleton pattern<br>
- use of JMS and MDBs<br>
- use of external rule server(s)<br>
<br>
Any thoughts about scalability issues?<br>
