Hi, try printing the whole message structure by adding the property "printfull" and setting it to "true" on the SystemPrintln action. This will show the location of the Task object in the message. By the look of this: <object-path esb="body.Task" /> you are expecting it to be bound under the location 'Task'. One quickstart that might help you out is the business_rules_service quickstart.
