[rules-users] Rule processing blocking when I/O is involved in a BPMN 2.0 Task

Hi, Our setup consists on some BPMN process being executed when a rule fires. Our process has a node of type Task for which a handler is available at the knowledge session. Our handler invokes a web service and waits ( blocks ) for the response before completing the task and letting the BPMN process continue. Well, we've inserted a hundred facts in the session that trigger the rule that triggers the BPMN process that triggers the web service call ... what we are seeing ( using the statistics gathered using JMX and our own experience ) is that 100 rule activations are created and only one fires, the rest, are "waiting" for the web service to respond. When the web service responds then another rule fires, and so on. For an iliterate point of view, seems that there's only one thread for it all, drools expert, fusion and flow ... Our session is stateful and we this is how we manage our session: new Thread(new Runnable() { public void run() { session.fireUntilHalt(); } }).start(); How do we get the rules to fire in parallel? Is there any better way to get this done ( to get the processes executed in parallel and not blocking the execution of the rules)? Greets, Alberto R. Galdo argaldo(a)gmail.com
