Web Services Combination Of Information Island Based On Open Workflow Engine Shark

Formulation of workflow came from the early people's craft workflow and manage in thework, and the efficiency is very low, with development of the network technology of the computerand distributed technology, workflow have offered deep technical support for computerizationThe key technology of workflow is the workflow engine, also called the workflow machine.According WfMC the standard defined five major interfaces which are exchanging, workflow clientend user interface, workflow application interface, communicate interface, system management andcontrol, But it is not very perfect that a lot of open project is finished, for example unusual andtransaction processing. Workflow complicated to remain step of improvements also.Our research work is to launch from then on. My groundwork is to apply distributed theory andresearch to the work in the engine, to the present and distributed rapid development. We havealready reached two goals:1.Adopts present and ripe distributed technology, make communication among the enginemachines;2.Directed against present internet users' characteristic, we adopt Java technology and WebServices technology, make workflow engine become an irrelevant and stepping the technology of thelanguage platform.
