View Page HistoryEasyBPEL is a library that provides BPEL 2.0 workflow management to orchestrate services based on a WSDL description. Easy BPEL can manage WSDL 1.1 and WSDL 2.0 descriptions for its partners, thanks to [EasyWSDL|easywsdl:EasyWSDL Overview].
As illustrated in the following figure, it is mainly composed of a BPEL compiler and a BPEL definition registry.
It embeds also [EasyVIPER|easyviper:], a workflow engine allowing to execute BPEL processes. Indeed, the BPEL Compiler generates EasyVIPER executable process instances.

EasyBPEL is typically used within an execution environment that manages BPEL deployment and message exchanges. The EasyBPEL layer compiles BPEL files and store them into
a Process Definition registry. It generates at least one EasyVIPER workflow corresponding to the BPEL definition. The EasyVIPER engine performs finally the workflow execution.
