A method is provided for providing unit of work continuity between a client device and a server when the client device initially fails to complete an ongoing unit of work. The method includes temporarily storing, in a temporary storage location in the server, in-doubt messages sent to the server for the ongoing unit of work, when the client device disconnects from the server without committing the ongoing unit of work so that the client device does not have to resend the in-doubt messages to the server. The method further includes utilizing unique hash-codes to identify the in-doubt messages the client device had earlier sent so that the server can retrieve the in-doubt messages from the temporary storage location and include the in-doubt messages as part of the ongoing unit of work to be committed by the client device. The ongoing unit of work is only part of an entire transaction.
