Creating a SOA Composite Application with Oracle JDeveloper 12c
Before You Begin Purpose This Oracle by Example (OBE) tutorial shows you how to develop a HelloWorld composite application from start to finish in Oracle SOA Suite 12c.
Time to Complete 30 minutes
Background Oracle SOA Suite provides an enterprise architecture that supports building connected enterprise applications to provide solutions to business problems. Using Oracle SOA Suite, you can create, manage, and orchestrate services into composite applications and business processes. You can then easily assemble multiple technology components into one SOA composite application. A SOA composite application is an assembly of services, service components, and references designed and deployed in a single application. Connections(wiring) between the services, service components, and references enable message communication. The details for a composite are stored in the composite.xml file.
Context This is the second tutorial of a series that shows you how to install Oracle SOA Suite 12c, develop a HelloWorld application from the beginning, and deploy an application locally and to the cloud.

5. On the Expression panel, leave the cursor active after the comma. Expand inputVariable, payload, and client: process under the BPEL Variables panel, select client:input string, and click Insert Into Expression. View Image Description of this image
Note: You can also drag and drop the client:input String to the Expression text area. 6. On the Expression panel, verify your expression, and click OK.
Description of this image
The Edit Assign page appears with the function added into the Drag panel. 7. On the right side panel of the Edit Assign page, expand the outputVariable client:MakeGreetingResponseMessage(x), payload, and client:processResponse,and then drag and drop the function to the client:result string.
Description of this image
The function wires(connects) the client: input string from the inputVariable and the client:result string from the outputVariable.
Description of this image
8. On the Edit Assign page, select the General tab, in the Name field enter Assign_Greeting, and click OK.
Description of this image
The Edit Assign page closes and the MakeGreeting.bpel page appears again. Verify your MakeGreeting.bpel page contains the Assign activity.
