BPEL Import (BizTalk Server Sample)

  • Artigo

The BPEL Import sample demonstrates how to create an orchestration from a Business Process Execution Language (BPEL) process description and its related artifacts.

What This Sample Does

Wide World Importers is a shipping company that provides automated shipping services to retailers. Specifically, Wide World Importers enables retailers to:

  • Request order shipments

  • Track shipments

  • Confirm shipments

  • Confirm invoicing and payment for shipments

    While the availability of these services can be represented by using a Web Services Description Language (WSDL) document, a BPEL document describes the typical way in which the product companies are expected to call the services and how to expect responses from Wide World Importers.

    When Northwind Traders hires Wide World Importers to handle their shipping, they are provided a BPEL file and some related artifacts that describe the entire interaction. Using the BPEL file, Northwind Traders creates a BizTalk Server application (BPELShipping) to automatically process orders through Wide World Importers.

    This sample walks you through this scenario in which the BPELShipping application:

  1. Receives an order from the Northwind Traders customer order system.

  2. Sends a shipping request to Wide World Importers and requests confirmation.

  3. Receives shipment request confirmation from Wide World Importers.

  4. Receives pickup notification from Wide World Importers.

  5. Receives shipment status messages up to and including when the shipment has been received by the customer.

  6. Receives an invoice from Wide World Importers.

  7. Responds to Wide World Importers with an invoice acknowledgment.

  8. Receives a payment confirmation from Wide World Importers.

  9. Sends a final shipping confirmation to the ordering system.

    A separate BizTalk application (ShipperProcess) is used to simulate Wide World Importers for this sample. The BPELShipping application communicates with ShipperProcess by using the FILE transport, which uses common file system locations for the communication.

How This Sample is Designed and Why

BPEL for Web services is an XML-based language to describe the business process so that it can be easily shared across different companies who want to do business with each other using Web services. BPEL describes how to handle the business process at the business protocol level, but it does not describe the internal process in a company, such as the steps a company would take to process a purchase order after receiving it from a partner. This sample is designed to show you how to import BPEL and corresponding WSDL files, convert them into an orchestration, and then start to run the business process with the partner.

The following is the step-by-step procedure showing how to import the BPEL and WSDL files and convert them into an orchestration to interact with a prebuilt BizTalk application (ShipperProcess). If you complete the following steps, you do not need to perform the steps described in "To build and initialize the BPELShipping application".

To import from BPEL and build a working solution

  1. In Microsoft Visual Studio, on the File menu, click New, and then click Project.

    Note

    Before completing this procedure, you must set up the ShipperProcess application to create the supporting processes and schema projects.

  2. In the New Project dialog box, in the Project Types pane, select BizTalk (Projects). In the Templates pane, select BizTalk (Server) BPEL Import Project.

  3. In the Name box, enter BPELShipping.

    Note

    If you use a different name, you may experience problems with the final binding step.

  4. Select a location for the project, and then click OK to start the BPEL Import Wizard.

  5. On the Welcome page, click Next.

  6. On the Select BPEL, WSDL, and XSD Files page, click Browse.

  7. Select all the files from the <Samples Path>\Orchestrations\BPELImport\BPELSource folder, click Open, and then click Next.

    Note

    In this step, you select the BPEL and WSDL files to describe the business process and the XSD files to represent the business document schemas.

  8. On the Select WSDL Files for Invoked WebServices page, click Finish.

  9. After the BPEL Import Wizard reports a successful import, close the wizard. The project is now created.

  10. At the Visual Studio command prompt, change directory (cd) to the project location.

  11. Run the following command:

    sn –k BPELShipping.snk

  12. In Solution Explorer, right-click the BPELShipping project, and then click Properties.

  13. Under Common Properties\Assembly, select the assembly key file BPELShipping.snk created in step 11, and then click OK.

  14. In Solution Explorer, select all the .xsd files and delete them.

  15. In Solution Explorer, select Add Reference, and on the Projects tab, click Browse.

  16. Select ShippingSchemas.dll from the location <Samples Path>\Orchestrations\BPELImport\Solution\ShipperProcess\ShippingSchemas\bin\Development, and then click OK.
