Subject: Issue - 30 - Support for coordination protocol
This issue has been added to the wsbpel issue list. It is in the current version of the list at wsbpel document 2656, It is hoped to have a fixed url for the ever-changing list.
Support for use of coordination protocols for invoking services by process and when process invoked by another service.
Clarify use of coordination protocol to: - Establish a shared execution context with a shared outcome - Cancellation of any pending work at the request of the coordinator - Notification of completion or failure by the participant - Compensation of any completed work at the request of the coordination - Notification of (compensation) completion or failure by the participant
Clarify how a compensation handler in the process is used to invoke compensation handler of a service such coordinated. Clarify how the compensation handler of the process is invoked by such a service. Clarify how parameters are passed to and from compensation handler when invoked in such a manner.
Clarify the relationship between the scope in which an invocation is performed and the context that governs the coordination, where to wait for the completion of work by the participant, when to cancel such work, and how to be notified of general failure.
Also, investigate means to determine whether service supports
coordination as part of the process definition (where only its interface
is known), and how a process advertises this capability as part of its
interface definition, e.g. using WSDL 1.2 F&P.
