Creating an Application and a Project with a BPEL Process

Learn how to create an application and a project with a BPEL process.

This tutorial makes the following assumptions:

  • Oracle SOA Suite is installed on a host on which the SOA Infrastructure is configured.

  • You are familiar with basic BPEL constructs, including BPEL activities and partner links, and basic XPath functions. Familiarity with the SOA Composite Editor and Oracle BPEL Designer, the environment for designing and deploying BPEL processes, is also assumed.

Create a file named VacationRequest.xsd with the following syntax. This file includes the schema for the vacation request and subsequent response. 

<schema attributeFormDefault="qualified" elementFormDefault="qualified"
        targetNamespace="http://xmlns.oracle.com/VacationRequest"
        xmlns="http://www.w3.org/2001/XMLSchema">
 <element name="VacationRequestProcessRequest">
  <complexType>
   <sequence>
    <element name="creator" type="string"/>
    <element name="fromDate" type="date"/>
    <element name="toDate" type="date"/>
    <element name="reason" type="string"/>
   </sequence>
  </complexType>
 </element>
 <element name="VacationRequestProcessResponse">
  <complexType>
   <sequence>
    <element name="result" type="string"/>
   </sequence>
  </complexType>
 </element>
</schema>

To create an application and a project with a BPEL process:

  1. Start Oracle JDeveloper. From the File main menu, select New > Applications > SOA Application.

    Click OK.

  2. In the Application Name field, enter VacationRequest, and click Next.
  3. In the Project Name field, enter VacationRequest, and click Next.
  4. In the Composite Template list, select Composite with BPEL Process, and click Finish.

    The Create BPEL Process dialog appears.

  5. In the Name field, enter VacationRequestProcess.

    Go to the bottom of the Create BPEL Process dialog.

  6. To the right of the Input field, click the Search icon.

    The Type Chooser dialog appears.

  7. In the upper right corner, click the Import Schema File icon.

    The Import Schema File dialog appears.

  8. Browse for and select the VacationRequest.xsd file.

    Click OK until you are returned to the Type Chooser dialog.

  9. Select the input element VacationRequestProcessRequest, and click OK.

    You are returned to the Create BPEL Process dialog.

  10. To the right of the Output field, click the Search icon.
  11. Select the output element VacationRequestProcessResponse, and click OK.

    You are returned to the Create BPEL Process dialog.

  12. Accept the default values for all other settings, and click OK.

    A BPEL process service component is created in the SOA Composite Editor. Because Expose as a SOAP service was selected in the Create BPEL Process dialog, the BPEL process is automatically connected with a service binding component. The service exposes the SOA composite application to external customers.
