Abstract: The paper describes an application composition and execution environment implemented as a transactional workflow system that enables sets of inter-related tasks to be carried out and supervised in a dependable manner. The paper describes how the system meets the requirements of interoperability, scalability, flexible task composition, dependability and dynamic reconfiguration. The system is general purpose and open: it has been designed and implemented as a set of CORBA services, running on top of a given ORB. The system serves as an example of the use of middleware technologies to provide a fault-tolerant execution environment for long running distributed applications.
