Method of handling a message

A messaging system comprising a message source, a message receiver and a message service intermediate of the message source and message receiver, wherein a compensation component is established at the message source, further comprising a microprocessor coupled to memory, wherein the microprocessor is programmed to implement the message service, the message service having a plurality of queues, wherein:

• the message source is arranged to transmit a one way message, wherein the one way message is part of a business transaction, the business transaction comprising a plurality of one way messages,
• the message service is arranged to receive the message and to transmit the message through at least two of the plurality of queues in turn,
• the message receiver is arranged to receive the message, to process the message, and to transmit a communication, the communication indicating success or failure of the processing of the message,
• the messaging service is arranged to perform a transaction confirmation for each queue of the plurality of queues that received and transmitted the message, in turn, and
• the messaging service is arranged to receive the communication, the message service being, responsive to receiving an indication of a failure of part of the transaction when the communication indicated that processing of the one way message succeeded, operable to cause compensation logic defined by the compensation component to execute.

A method of operating a message service in a messaging system, the message service having a plurality of queues, where the messaging system comprises a message source, a message receiver and the message service intermediate of the message source and message receiver, the method comprising:

• receiving a one way message, as part of a business transaction, from the message source, the transaction comprising a plurality of one way messages,
• receiving the message into and transmitting the message from, at least two of the plurality of queues of the message service in turn, using a processor, by:
• receiving the message at a first one of the plurality of queues of the message service,
• transmitting the message from the first one of the plurality of queues to a second one of the plurality of queues, and
• transmitting the message from the second one of the plurality of queues of the messaging service,
• transmitting the message from the messaging service to the message receiver for processing thereat,
• receiving a communication from the message receiver, the communication indicating success or failure of the processing of the message,
• performing, with a processor, a transaction confirmation for each queue of the first one and second one of the plurality of queues, in turn, and
• responsive to receiving an indication of a failure of part of the transaction when the communication indicated that processing of the one way message succeeded, causing compensation logic defined by a compensation component established at the message source to execute.

A message service having a plurality of queues, where the message service is intermediate of a message source and a message receiver in a messaging system, the message service comprising:

• a microprocessor coupled to a memory, wherein the microprocessor is programmed to implement the message service by:
• receiving a one way message, as part of a business transaction, from the message source, the transaction comprising a plurality of one way messages, wherein receiving a message comprises receiving the message into and transmitting the message from, at least two of the plurality of queues of the message service in turn, by:
• receiving the message at a first one of the plurality of queues of the message service,
• transmitting the message from the first one of the plurality of queues to a second one of the plurality of queues, and
• transmitting the message from the second one of the plurality of queues of the messaging service,
• transmitting the message from the messaging service to the message receiver for processing thereat,
• receiving a communication from the message receiver, the communication indicating success or failure of the processing of the message,
• performing a transaction confirmation for each queue of the first one and second one of the plurality of queues, in turn, and
• causing compensation logic defined by a compensation component established at the message source to execute, responsive to receiving an indication of a failure of part of the transaction when the communication indicated that processing of the one way message succeeded.
