MANAGING TASK OBJECT STATE UTILIZING A RELIABLE MESSAGING MODEL

摘要

Embodiments of the present invention address deficiencies of the art in respect to task object state management for workflow management systems and provide a novel and non-obvious method, system and computer program product for managing task object state utilizing a reliable messaging model. In an embodiment of the invention, a method for managing task object state utilizing a reliable messaging model is provided. The method includes transmitting according to a reliable messaging protocol a launch request for a task object in a workflow over a computer communications network to a remote server. The method also includes determining from the reliable messaging protocol whether or not the launch request has failed. Finally, the method includes responding to a determination that the launch request has failed, by transmitting a test request to the remote server using a protocol other than the reliable messaging protocol and setting a state of the task object as failed only if the remote server responds to the test request.
