Developing web services - Transaction support (WS-Transaction)
WS-Transaction is an interoperability standard that includes the WS-AtomicTransaction, WS-BusinessActivity, and WS-Coordination specifications. The Web Services Atomic Transaction (WS-AT) support in the application server provides transactional quality of service to the web services environment. Distributed web services applications, and the resources they use, can take part in distributed global transactions. With Web Services Business Activity (WS-BA) support in the application server, web services on different systems can coordinate activities that are more loosely coupled than atomic transactions. Such activities can be difficult or impossible to roll back atomically, and therefore require a compensation process if an error occurs. Web Services Coordination (WS-COOR) specifies a CoordinationContext and a Registration service with which participant web services can enlist to take part in the protocols that are offered by specific coordination types.
