Research of Web Services Composition Transaction Coordination Framework Based on BPEL and WS-TX
基于BPEL和WS-TX的Web服务组合事务协调框架研究

As composite service process must be manually defined when using Web service transaction coordination framework because of lack of process definition support, a transaction coordination framework which supports process and transaction semantic information automatic extracting was proposed. It coordinates the composite service by using transaction coordinator defined by Web services transaction (WS-TX) and extracting coordination information from extended business process execution language (t3PEI).The proposed framework combines the advantages of both W} TX in the transaction coordination and BPEI. in business process design to separate transaction logic from business logic effectively. Finally the effectiveness of the framework was validated through a case study.
