BPEL(Business Process Execution Language) is a formal specification language for the automated business procedure to describe the Web service composition,while the Apache ODE BPEL execution engine is responsible for parsing and executing the definition of BPEL processes to provide the operating environment.However,the deployment and implementation of the Apache ODE BPEL engine process requires the WSDL description of various services and the combined service,and the description file for the process deployment,Apache ODE does not provide the tools to complete these functions.Based on analyzing the structure and deployment of Apache ODE,as well as the principle of BPEL process execution,designan algorithm to generate the description file for the process deployment and the WSDL description of services,thus automate completing of service composition,deployment and implementation in Apache ODE engine environment.
