Abstract: To solve the inter-operation of the workflow engines running on the Microsoft.net, CORBA and J2EE platforms and realize the integration of the distributed and heterogeneous enterprise application systems, the inter-operation framework for dynamic workflow was presented based on the WS-Resource mode. As for WS-Resource mode, the grid services and web services were regarded as the atomic call unit, and the XML-based SOAP-message was adopted as the communication mechanism at bottom level of workflow so as to solve heterogeneous applications. Message queue, transaction, maintenance and failure rollback of the workflow engine were managed by the WS-Resource container. Finally, in the inter-operation framework of the workflow engines, the three-tier workflow mode was constructed including global workflow engine oriented to cross-enterprise integration, local workflow engine oriented to interior-enterprise heterogeneous platform integration and local workflow engine oriented to the same platform within an enterprise.
