BPEL 1.1 Model

Enterprise Architect uses BPMN 1.1 as a graphical front-end to capture BPEL 1.1 Process description ( as BPEL 1.1 does not have not a standard graphical notation ). Enterprise Architect uses the partial mapping specified in the OMG BPMN 1.1 specification to map BPMN 1.1 constructs to BPEL 1.1.

Model the BPEL Process using the constructs in the BPMN 1.1 Core toolbox. Use the following constructs in this toolbox to model BPEL 1.1:

BPMN 1.1 - Core page:

  • BPEL Process
  • Activity
  • Start Event
  • Intermediate Event
  • End Event
  • Gateway
  • Pool


BPMN 1.1 - Relationships page:

  • Sequence Flow
  • Message Flow
  • Association


BPMN 1.1 Types page:

  • Assignment
  • Condition
  • Message
  • Participant
  • Web Service

Generate BPEL 1.1


  • Generating BPEL 1.1 from a BPMN 1.1 model is supported in the Business and Software Engineering and the Ultimate editions of Enterprise Architect.
  • Ensure that BPMN 1.1 Technology is enabled in the MDG Technologies dialog ( Settings | MDG Technologies ).

BPEL 1.1 Example:

  • The Enterprise Architect Example file ( EAExample.EAP ) has a sample BPMN 1.1 model from which BPEL 1.1 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 1.1 model package is in: Project Models | Analysis and Business Modeling | BPEL Example | BPEL 1.1 Model.

Modeling Restrictions:

  1. Every BPEL Process and Sub-Process should start with a Start Event and end with an End Event.
  • A Start Event or an End Event should not be attached to the boundary of a Sub-Process.
  1. Sequence Flow Looping is not supported - only Activity looping is supported. All Sequence Flows should flow downstream and not upstream.
  2. Mapping of an Intermediate Event with multiple triggers to BPEL 1.1 is not supported.
  3. Mapping of Multi-Instance Parallel While loops to BPEL 1.1 is not supported.
  4. Mapping of Independent Sub-Process to BPEL 1.1 is not supported.
  5. Pools are treated as black box ( i.e., they do not expose any details ) and hence they cannot contain any child elements or have any incoming/outgoing Sequence Flow connectors.
