Abstract:
1. A method of operating a gateway to act as a conduit for a structured transaction between a first transaction peer and a second transaction peer, the structured transaction having at least a begin message for opening a logical communication path, a continue message for maintaining a logical communication path and an end message for closing a logical communication path, the method comprising: receiving a first begin message from the first transaction peer, the first begin message including a context name; receiving from the first transaction peer a continue message having a request element; determining a routing key identifying the second transaction peer from the continue message; constructing and sending a second begin message, including the continue message, to the second transaction peer, the second begin message constructed at least by extracting the parameter from the continue message, determining the context name using the parameter, and including the retrieved context name in the second begin message; receiving a first end message including a response element from the second transaction peer; constructing and sending a second end message including the response element to the first transaction peer; and responding to the first begin message with a return continue message that includes a parameter identifying the context name.
