RESUMO

Computing systems consist of a multitude of hardware and software components that may fail. For this reason, the transaction mechanism has always been essential for the development of robust systems. Transactional support for the Web services technology was defined in August 2005, in a set of three specifications, namely WS-Coordination, WS-AtomicTransaction, and WS-BusinessActivity. Together, such specifications enable the development of robust Web services applications. In this dissertation we studied atomic transactions in the Web services realm. Particularly, we added Web services atomic transaction support to the existing JBoss application server transaction manager. Furthermore, we evaluated the performance of this transaction manager when it employs each of the following remote method invocation mechanisms: Web services/SOAP, CORBA/IIOP and JBoss Remoting. Finally, we performed scalability and interoperability experiments.
