This paper presents a peer-to-peer approach to execution of BPEL processes. It does not pre-allocate resources as in existing decentralized approaches. Nor does it involve global coordination for normal executions. The approach is of continuation-passing style, where continuations, or the reminder of executions, are passed along with messages for process execution. Two continuations are associated with an execution: a success continuation and a failure continuation. Recovery plans for processes are automatically generated at runtime and attached to failure continuations.
