Enabling Grid Services from BPEL process using ODE engine

摘要

Grid services and workflows with BPEL have gained much interest in Grid computing recently as they allow useful structured tasks to be composed and invoked automatically within a Grid environment. With stateless Web services, the composition and invocation can be done with BPEL and its engines such as ActiveBPEL and ODE. However, the invocation of Grid services presents a problem for BPEL and its engines because they lack features for supporting stateful services. This paper investigates the issue and presents a clean solution that allows BPEL-ODE invocation of Grid services.
