This document provides information about a sample that demonstrates integrating business processes with the SOA Event Delivery Network (EDN). It includes requirements for running the sample, an overview of the sample processes and events, and instructions for deploying and testing the sample. The sample shows three EDN integration scenarios: 1) publishing an EDN event from a process, 2) starting a process by subscribing to an EDN event, and 3) receiving a correlated EDN event within a process. Running the sample allows viewing the end-to-end flow triggered by EDN events passing between the sample processes.

2. Introduction
A frequently asked question is whether BPM processes can make use of SOA Event Delivery
Network (EDN) Events. EDN allows publish and subscribe interactions between SOA
components without exposing the details of the transport. Events are typed based on XML
Schema and named via an EDL file. Additional details about EDN can be found in:
SOA Developers Guide:
http://docs.oracle.com/cd/E23943_01/dev.1111/e10224/obe_intro.htm#CHDIBHBE

Within BPM processes, EDN integration is supported and is surfaced through BPMN signal throw
and catch events. The following diagram illustrates that the “implementation” of a signal is
selecting the associated EDN event, providing the output data association, and (optionally)
specifying the correlation:
The mapping of BPNM signals to EDN events enables the following integration scenarios:
1. Starting a BPM process instance based on subscription to an EDN event via a BPMN signal
start event.
2. Throwing (publishing) an EDN event via a BPMN signal throw or end event.
3. Receiving a correlated EDN event via a BPMN signal catch event.
Note: in this release there are two limitations to be aware of:
1. Currently you cannot use BPMN signal events to communicate within the same process.
2. You cannot subscribe to uncorrelated EDN events using a BPMN signal catch event. You can
only use uncorrelated EDN events to start a process instance (i.e. any subscription within an event
subprocess must be correlated).

3. Environment Requirements
This sample requires JDeveloper version 11.1.1.6 or higher with the SOA Composite Editor and
BPM Studio extensions installed. A standalone server with BPM Suite 11.1.1.6 (or higher) and a
domain configured with BPM Suite is required for deploying and running the sample.
4. Installation and Configuration
The sample is provided as a zipped JDeveloper application. The application can be unzipped into
any location where the path name does not include spaces. To open the application, use the
“Application Open” menu and locate the file: bpm-102-EDN-integration.jws. The application
contains 2 projects:
 BpmEdnIntegrationSample – A BPM project that includes two BPM processes used to
illustrate EDN integration.
 Resources – A generic project that contains documentation and ANT build targets to
package this sample.
4.1 Deploy the Composite Project
Use JDeveloper to deploy the composite. EDN is preconfigured in SOA domains. So no
additional configuration of EDN is required.
After deployment, you should be able to see auto-registered EDN subscriptions for the sample
processes in Enterprise Manager (EM):

5. Sample Overview
The goal of this sample is to illustrate the 3 EDN integration scenarios described in the
introduction. The following reflects the order used within the sample.
1. Throwing (publishing) an EDN event. The OrderProcess is started with a message receive
event and the process immediately publishes an OrderCreatedEvent via a BPMN signal throw.
This results in a publish of then associated EDN event.
2. Starting a process on receipt (subscription) of an EDN event. The CreateOrderEventListener
process includes a BPMN start signal event which is mapped to an OrderCreatedEvent
subscription. This causes an instance of the CreateOrderEventListener to be created. Note
that this is pub/sub so the OrderProcess is decoupled from the CreateOrderEventListener
process and other components could also have subscribed to the same event.
3. The OrderProcess has a correlated BPMN signal catch event within the event subprocess. In
this case the correlation key is the orderId. This results in the OrderUpdatedEvent being
received only by the originating OrderProcess. Note that other components could also
subscribe to this event (i.e. EDN is not aware of the correlation). However only the BPM
instance with the matching correlation key will receive the event.

6. Running the Sample
To run the sample, log into Enterprise Manager (EM) and navigate to the Test Page for the
BpmEdnIntegrationSample project. Enter an orderId and then select “Test Web Service”.
In the audit trail you will see:
1. The publishing of the OrderCreatedEvent, which causes an instance of the
CreateOrderEventListener process to be created.
2. The OrderUpdateEvent being published and received by the original OrderProcess, which
then results in the human task being withdrawn (from within the event subprocess).
