Transactions and Activity Services

Interesting bit of history of the WS-Coordination framework from Mark Little's WebLog about the J2EE Activity Service.

This defines an infrastructure to support a wide range of extended transaction models. The architecture is based on the insight that the various extended transaction models can be supported by providing a general purpose event signaling mechanism that can be programmed to enable activities (application specific units of computations) to coordinate each other in a manner prescribed by the extended transaction model under consideration.
