Apache ODE (Apache Orchestration Director Engine) 'executes' or 'runs' one or more business processes which have been expressed in the Web Services Business Process Execution Language (WS-BPEL). It principally communicates with one or more Web services, sending and receiving messages, manipulating data and handling exceptions ('errors') as defined by any given process. The engine is capable of running both long and short living processes to coordinate all the services that make up a service or application (orchestration).
