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.

1

Create a BPEL 1.1 Package Structure.

Alternatively:

  • 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

2

Open the BPEL diagram under the <<BPELProcess>> stereotyped element.

3

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

4

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

 BPEL Web Service

5

Generate BPEL 1.1 code from the BPEL Process.

 Generate BPEL 1.1

Notes

  • Generating BPEL 1.1 from a BPMN 1.1 model is supported in the Unified and the Ultimate editions of Enterprise Architect
  • Ensure that BPMN 1.1 Technology is enabled in the 'MDG Technologies' dialog ('Specialize > Technologies > Manage')

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: Example Model > 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 (that is, they do not expose any details) and hence they cannot contain any child elements or have any incoming/outgoing Sequence Flow connectors
