You would not need to send any input to a node, but rather you would need to send the input to a specific process instance which is waiting for that input on a node. So the external system needs to know the id or the instance that is waiting. (Or any qualifier that would find one or more processes, i.e. any process where Company Name = 'Dutch Beer Co'.) If you were going to send a message out to the external system informing it that your workflow is ready for some input, you could pass some kind of instance ID in the message and have the external system send it back with their input. Your processing logic then becomes something like 1. parse id 2. get instance 3. parse input 4. signal instance with input View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989157#...
