Abstract :
The existing Web service transaction (WST) models and protocols depend too much on web service providers when solving concurrent conflicts or performing rollback, which make individual service providers bear big burden, and the cost for rolling back a WST may be very high. In this paper, we present a novel concurrency control mechanism named Jenova, which incorporates two enhancements to support WSTs: nested transactions and admission control. Jenova can provide a higher degree of concurrency for WSTs and the cost of rollback can be greatly decreased. The prototypal framework on the J2EE platform and the experiments prove the efficiency of the mechanism
