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.
How to
|
|
|
|
1
|
Create a BPEL 2.0 Package Structure.
Alternatively:
|
|
|
a
|
Create a package in the Project Browser.
|
b
|
Click on the New Diagram icon in the Project Browser toolbar.
|
c
|
Select BPMN 2.0 in the Select From field and BPEL in the Diagram Types field.
|
d
|
Click on the BPEL icon from the BPMN 2.0 - Business Process Toolbox and drag it into the created BPEL diagram.

|
Open the BPEL diagram under the BPELProcess stereotyped element.
|
|

|
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:

Notes
| • | 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:
| • | 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-Process |
| • | Boundary Intermediate Event |
| • | Task and Intermediate Event 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
