BPEL Overview
BPEL Stands for Business Process Execution Language, A standard for integrating discrete services into end to end process flows.

10+ years of R&D from Oracle, MSFT, IBM.  SOAP but also Java, JCA.  Rich Flow Semantics.  Optimized Bindings. XPATH+XSLT+XQuery A Process is a Service.

JDeveloper BPEL Designer
 BPEL Designer provides a graphical and user-friendly way to build BPEL processes.

KEY FEATURES

• Native BPEL Support • Drag-and-drop process modeler
• UDDI and WSIL service browser

• Visual XSLT mapper
• Visual XPATH editor • Visual Assign editor • One-click build and deploy

Basic Activities
•

receive

Do a blocking wait for a matching message to arrive Send a message in reply to a formerly received message Invoke a one-way or requestresponse operation Update the values of variables or partner links with new data Validate XML data stored in variables A “no-op” instruction for a business process

throw

Generate a fault from inside the business process Forward a fault from inside a fault handler

reply

•

rethrow

invoke

•

exit

Immediately terminate execution of a business process instance Wait for a given time period or until a certain time has passed Invoke compensation on an inner scope that has already completed

assign

BPEL Console
The BPEL Console provides a mature web-based interface for management, administration and debugging of processes deployed to the BPEL server. Audit trails and process history/reporting information is automatically maintained and available both through the BPEL Console and Java API.

Visual monitoring. Auditing.  BPEL debugging.  Lifecycle management of in-flight instances Performance tuning Partitioning/BPEL domains

Sample Business Process with Portal

Getting Started
Creating Workspace Application Navigator->Applications(rt click) ->New Select Workspace from right menu and click OK. Enter the Workspace name. Workspace created can be viewed in the Application Navigator on the left.

Creating Project Right Click Workspace Name->New Project Under Categories – select General -> Projects. On the Items Window, BPEL Process Project ->OK. Enter the BPEL Process Name. Namespace is optional. In the Template, select Asynchronous BPEL process. Use Default and OK. The New project created will be visible in C:/Oracle_Home/integration/jdev/jdev/mywork/Workspa ceName/ProcessName

Getting Started

JDeveloper BPEL Designer will show 5 panes.  Center Pane -> BPEL Process. Navigator on Left ->Workspaces, Projects, Project Source Files Structure pane on lower left -> Info about Currently Selected Files. Message Log -> On the bottom of the screen.  Component Palette -> Process Activities available for Drag & Drop.

Getting Started

To review the WSDL Interface of Asynchronous Process.

 In the Navigator, Double click the .wsdl file.
Can view & Edit the Code.

<!-- portType implemented by the CreditFlow BPEL process -> <portType name="CreditFlow"> <operation name="initiate"> <input message ="client:CreditFlowRequestMessage"/> </operation> </portType> <!-- portType implemented by the requester of CreditFlow BPEL process for asynchronous callback purposes --> <portType name="CreditFlowCallback"> <operation name="onResult"> <input message ="client:CreditFlowResponseMessage"/> </operation> </portType>

Getting Started

To view the BPEL Process.  In the Navigator, Double click the .bpel file. Initial view .consists of 3 Swim Lanesi) Partner Links ->Colored outer swim lane. ii) Process Flow -> Center swim lane. iii) Partner Links -> Rt side swim lane.

Getting Started

Review the BPEL Source Code. Click on the Source Tab at the bottom of the BPEL Window. Scroll down to view and edit the code.

Getting Started

Add activities to the Process Map. Insert the Scope activity.

Getting Started

Adding Scope Activities to Process Map. Give the name of Scope activity.

Getting Started

Creating Partner Link - Partnerlinks represent services that BPEL processes can call or interact with. From the Component Palette, drag and drop the .partnerlink activity into the right swimlane.

i) Enter the name of Partnerlink. ii) Select the flashlight icon above the WSDL File text area iii) select the service endpoint

iv) The wizard presents an explorer listing all the services deployed on the local Oracle

Navigate to LocalBPELServer > processes > default > CreditRatingService.
