You can generate BPEL code from BPM objects that can be interpreted by any orchestration engine. A separate .BPEL file per each top-level process is generated, and contains the process descriptions. A .WSDL file (process language definition file) for the entire model is also generated.
When the generation is complete, the Generated Files dialog opens listing the files, each of which you can open, and review by selecting it, and clicking Edit.
