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 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.

Create a BPEL 1.1 Package Structure.


  • Create a Package in the Project Browser
  • Click on the 'New Diagram' icon in the Project Browser
  • Select 'BPMN 1.1' in the 'Select From' field and 'BPEL' in the 'Diagram Types' field
  • Click on the 'BPEL Process' icon from the BPMN 1.1 Core toolbox and drag it into the created BPEL diagram

BPEL 1.1 Package Structure Project Browser Toolbar


Open the BPEL diagram under the   BPELProcess stereotyped element.


Model the BPEL Process using the constructs in the BPMN 1.1 Core page of the Diagram Toolbox; use these constructs in each Toolbox page 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

BPMN 1.1 Core Toolbox Model BPEL 1.1 Process


Create Web Service for the BPEL Process and other related Pools, if required.

BPEL Web Service


Generate BPEL 1.1 code from the BPEL Process.

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 ('Extensions | 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

  • 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
  • Sequence Flow Looping is not supported - only Activity looping is supported; all Sequence Flows should flow downstream and not upstream
  • Mapping of an Intermediate Event with multiple triggers to BPEL 1.1 is not supported
  • Mapping of Multi-Instance Parallel While loops to BPEL 1.1 is not supported
  • Mapping of Independent Sub-Process to BPEL 1.1 is not supported
  • 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
