This chapter describes how to create the WebLogic Fusion Order Demo application in Oracle JDeveloper for Fusion Order Demo. It also describes how to create the PartnerSupplierComposite during the creation of the application.
Before following the instructions in this chapter, perform all the procedures in Chapter 1.
This chapter contains the following sections
See Chapter 1, "Introduction to the SOA Sample Application," for an overview of the WebLogic Fusion Order Demo application.
The PartnerSupplierComposite composite contains a BPEL process, ExternalPartnerSupplier. In the OrderBookingComposite composite, the Scope_RetrieveQuotes scope of the OrderProcessor BPEL process uses this process to obtain a quote from an external partner warehouse. When you create the Scope_RetrieveQuotes scope and the ExternalPartnerSupplier Web service in Chapter 6, "Creating the Second Half of the OrderProcessor BPEL Process," you reference the ExternalPartnerSupplier BPEL process.
Figure 3-1 shows PartnerSupplierComposite in the SOA Composite Editor.
In this procedure, you create the WebLogic Fusion Order Demo application, the PartnerSupplierComposite project, and the ExternalPartnerSupplier BPEL process. It contains the following tasks:
Task 1: Create the WebLogicFusionOrderDemo Application and the PartnerSupplierComposite Composite
Task 6: Initiate a Test Instance for the PartnerSupplierComposite Composite
Note:
Oracle SOA Suite is not automatically installed with Oracle JDeveloper. Before you can create an SOA application and project, you must install the Oracle SOA Suite extension. For instructions on installing this extension for Oracle JDeveloper, see the Oracle Fusion Middleware Installation Guide for Oracle JDeveloper.To create the WebLogic Fusion Order Demo application:
Open the New Gallery by choosing File > New.
Click the Current Project Technologies tab.
From either the All Technologies tab or the Current Project Technologies tab, in the Categories tree, select General, and then Applications.
From the Items list, select SOA Application.
Click OK.
On the Name your application page, enter the following values:
| Element | Value |
|---|---|
| Application Name | WebLogicFusionOrderDemo |
| Directory | Specify directory location directory_path\CompositeServices, such as C:\fod\CompositeServices. Oracle JDeveloper creates this directory, which acts as a container for all the projects.
This tutorial refers to the application directory that you specified as |
| Application Package Prefix | Do not enter a value. |
Click Next.
On the Name your project page, enter the following values:

For an introduction to the Application Overview, click F1 on the tab to display the online help. |
| composite.xml | This tab displays the PartnerSupplierComposite composite in the SOA Composite Editor.
For an overview of the SOA Composite Editor, see Oracle Fusion Middleware Developer's Guide for Oracle SOA Suite. |
| ExternalPartnerSupplier.bpel | This tab displays the ExternalPartnerSupplier BPEL process in the BPEL Designer.
For an overview of the BPEL Designer, see Oracle Fusion Middleware Developer's Guide for Oracle SOA Suite. |
Notice, too, the PartnerSupplierComposite project displays in the Application Navigator.
Click the composite.xml tab to view PartnerSupplierComposite composite. SOAP service binding component external_partnersupplier_client in the left swim lane provides the outside world with an entry point into the SOA composite application.
Click the WebLogicFusionOrderDemo.jws tab to view the contents of the WebLogicFusionOrderDemo application.
Select Save All from the File main menu to save your work.
Next, you create an assign activity to take the purchase amount and the order date and the current date as input variables to the ExternalPartnerSupplier service. An assign activity transfers data between variables, expressions, and other elements.
Click the ExternalPartnerSupplier tab.
Create the assign activity:
From the Component Palette, drag an Assign activity below the receiveInput receive activity.
Rename this activity by double-clicking the name underneath the icon. Do not double-click the activity icon itself.
In the edit field, change the name to AssignResponse.
Double-click the assign activity.
The Assign dialog displays.
Assign the purchase amount of the input to the OrderTotal variable for the ExternalPartnerSupplier service:
From the dropdown list, select Copy Operation:
The Create Copy Operation dialog appears.
On the From side, leave the Type selection as Variable and expand Variables > inputVariable > payload > client: WarehouseProcessRequest and select client:orderTotal.
On the To side, leave the Type selection as Variable and expand Variables > outputVariable > payload > client: WarehouseProcessResponse and select client:orderTotal.
Click OK to close the Create Copy Operation dialog and return to the Assign dialog.
The Copy Operation tab in the Assign updates to show the operation you created.
Assign the current date to the output deliveryDate variable for the ExternalPartnerSupplier service:
From the dropdown list in the Assign dialog, select Copy Operation.
The Create Copy Operation dialog appears.
On the From side, from the Type list, select Expression.
Select the XPath Expression Builder icon.
The Expression Builder displays.
In the Functions section in the lower right, from the menu, select Date Functions, and then select current-date from the menu options.
Click Insert Into Expression, and then click OK to return to the Create Copy Operation dialog.
On the To side, leave the Type selection as Variable and expand Variables > outputVariable > payload > client:WarehouseResponse and select client:deliveryDate.
Click OK to close the Create Copy Operation dialog and return to the Assign dialog.

In this task, you initiate a test instance of the PartnerSupplierComposite composite from the Test Web Service page in Fusion Middleware Control to verify the assign activity is working properly.
To initiate a test instance of the PartnerSupplierComposite composite:
Start Fusion Middleware Control. See Section 2.3.
From the SOA Infrastructure menu, select SOA Administration and select Common Properties.
On the Common Properties page, enter the following values to collect data for running instances:
| Element | Value |
|---|---|
| Audit Level | Development |
