BPEL 2.0 Model

Enterprise Architect uses BPMN 2.0 as a graphical front-end to capture BPEL 2.0 Process description ( as BPEL 2.0 does not have not a standard graphical notation ). Enterprise Architect uses the partial mapping specified in the BPMN 2.0 specification to map BPMN 2.0 constructs to BPEL 2.0.

Model the BPEL Process using the constructs in the BPMN 2.0 - Business Process toolbox. Use the following constructs in this toolbox to model BPEL 2.0:

  • BPEL
  • Activity
  • Data Object
  • Start Event
  • Intermediate Event
  • Event
  • Gateway
  • Pool

  • Sequence Flow
  • Association
  • Message Flow

Generate BPEL 2.0


  • Generating BPEL 2.0 from a BPMN 2.0 model is supported in the Business and Software Engineering and the Ultimate editions of Enterprise Architect.
  • Ensure that BPMN 2.0 Technology is enabled in the MDG Technologies dialog ( Settings | MDG Technologies ).

BPEL 2.0 Example:

  • The Enterprise Architect Example file ( EAExample.EAP ) has a sample BPMN 2.0 model from which BPEL 2.0 can be generated.
  • If you have installed Enterprise Architect at the default location, open this file: C:\Program Files\Sparx Systems\EA\EAExample.EAP
  • The BPMN 2.0 model package is in: Project Models | Analysis and Business Modeling | BPEL Example | BPEL 2.0 Model.

Modeling Restrictions:

  1. Every BPEL Process and Sub-Process should start with a Start Event and end with an End Event.
  • Boundary Start and End Events are not supported
  1. Sequence Flow Looping is not supported in both Normal and Exception Paths.
  • All Sequence Flows should flow downstream and not upstream.
  1. Sub-Process cannot be a Loop node and have boundary Intermediate Events.
  2. Event Sub-Process cannot act as a Loop Node.
  3. Assignments are not supported on :
  • Start Events on Event Sub-Process
  • End Events
  • Sub-Process
  • Boundary Intermediate Event
  • Gateway
  • Task and Intermediate Event that immediately follow an XOR Event Gateway
  1. Exception Path has to merge back into the Normal Path.
  • An exception to this rule is boundary Compensation Intermediate Event which should have a BPMN 2.0 Association to a Compensation Activity ( that has no incoming or outgoing Sequence Flows )
  • Multiple Exception Paths from an Activity must join at the same location in the Normal Path
  • An Exception Path should not cross another Exception Path.
  1. Activities in an Exception Path cannot have boundary Intermediate Events.
  2. Pools are treated as black boxes ( i.e., they do not expose any details ) and hence they cannot contain any child elements or have any incoming/outgoing Sequence Flow connectors.
