BPEL 2.0 Model

Enterprise Architect uses BPMN 2.0 as a graphical front-end to capture BPEL 2.0 Process descriptions (as BPEL 2.0 does not have 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.

Create a BPEL 2.0 Package Structure.


  1. Create a Package in the Browser window.
  2. Click on the 'New Diagram' option in the Browser window header drop-down menu.
  3. Select 'BPMN 2.0' in the 'Select From' field and 'BPEL' in the 'Diagram Types' field.
  4. Click on the 'BPEL' icon from the BPMN 2.0 - Business Process Toolbox and drag it into the created BPEL diagram.

Generate BPEL 2.0


  • Generating BPEL 2.0 from a BPMN 2.0 model is supported in the Unified and Ultimate Editions of Enterprise Architect
  • Enable the BPMN 2.0 Technology in the 'MDG Technologies' dialog ('Specialize > Technologies > Manage Technology')

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: Example Model > Analysis and Business Modeling > BPEL Example > BPEL 2.0 Model

Modeling Restrictions

  • 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
  • Sequence Flow Looping is not supported in both Normal and Exception Paths
  • All Sequence Flows should flow downstream and not upstream
  • Sub-Process cannot be a Loop node and have boundary Intermediate Events
  • Event Sub-Process cannot act as a Loop Node
  • Assignments are not supported on:
         -  Start Events on Event Sub-Processes
         -  End Events
         -  Sub-Processes
         -  Boundary Intermediate Events
         -  Gateways
         -  Tasks and Intermediate Events that immediately follow an XOR Event Gateway
  • 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
  • Activities in an Exception Path cannot have boundary Intermediate Events
  • Pools are treated as black boxes (that is, they do not expose any details) and hence they cannot contain any child elements or have any incoming/outgoing Sequence Flow connectors
