In Browser - Server Architecture, Application server with its database and Web Services are the major components of Distributed System. Web Services are modular applications that are self-contained and selfdescribing. The functions specified in the Web services are performed from simple requests to complicated business processes. In Distributed Transaction, the services are carried out by including the WS-Atomic Transaction (WS-AT) and WS-Business Activity (WS-BA) specification that belongs to family of Web Service Transactions. WS-AT implements core services such as Activation service, Registration service and Coordination service. WS-BA specification does not specify a standard way for an initiator to communicate with the coordinator of Business Activity. To ensure interoperability issues among the initiators and coordinators, BFT algorithm is an optimal solution. To achieve fault tolerance in Web service transactions, Lightweight BFT algorithm is proposed which uses source ordering instead of total ordering of incoming guests.
