That's a result of the tool using positional arguments and not being clever enough to detect that the binding key was not specified. You can have a null binding key by using e.g. qpid-config bind myExchange.headers myQueue '' any header1=header1Val, header2=header2Val The binding key for the headers exchange is used only for identity. You need it when unbinding and it must be unique for a given exchange and queue pairing. Null is valid value, but the uniqueness still applies so you can't have more than one binding between the same queue and exchange with a null binding key. --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:[email protected] _______________________________________________________ The information contained in this message may be privileged and conf idential and protected from disclosure.
