Walkthrough: Module 3 - Accessing SharePoint Properties from an Orchestration

This walkthrough is a continuation of Walkthrough: Module 2 - Integrating Office with the Windows SharePoint Services Adapter and shows you how to access the Windows SharePoint Services context properties of an incoming message at run time and then determine the destination of that message based on a property using dynamic ports in an orchestration. For an introduction to the Windows SharePoint Services adapter see What Is the Windows SharePoint Services Adapter?.

The following are prerequisites for performing the procedures in this topic:

For information about using the Windows SharePoint Services Adapter in a multi server deployment, see Setting Up and Deploying the Windows SharePoint Services Adapter.

In this procedure you modify the PurchaseOrder schema from Walkthrough: Module 2 - Integrating Office with the Windows SharePoint Services Adapter. This procedure illustrates how to promote a schema property for easy access in a BizTalk orchestration.

Modify the PurchaseOrder.xsd schema

  1. Click Start, point to All Programs, point to Microsoft Visual Studio 2010, and then click Microsoft Visual Studio 2010.

  2. Click File, click Open, and then click Project/Solution.

  3. Browse to the OrderProcess.sln file, and then click Open.

  4. In Solution Explorer, right-click the OrderProcessSchema.xsd file, and then click Open.

  5. In BizTalk Editor, expand PurchaseOrder.

  6. Right-click Amount, click Promote, and then click Quick Promotion.

  7. Click OK.

    noteNote
    Visual Studio creates a property schema for this in the current project.

  8. Save PurchaseOrder.xsd.

In this procedure you create a new BizTalk orchestration. This procedure creates the orchestration that is used to process a message received by the Windows Sharepoint Services adapter.

Add a BizTalk orchestration

  1. In Solution Explorer, right-click the OrderProcess project, click Add, and then click New Item.

  2. Under Categories, select Orchestration Files.

  3. Under Templates, select BizTalk Orchestration.

  4. Type MyCompanyOrderProcessing in the Name field, and then click Add.

In this procedure you create a new message, receive port, and receive shape for the orchestration. This procedure illustrates how to configure an orchestration to receive a message from BizTalk Server.

Create a new message

  1. In Orchestration View, right-click Messages, and then click New Message. This will generate a new message with the name Message_1.

  2. Right-click Message_1, click Rename, and then type Message_PO.

  4. Select Use an existing Port Type.

  5. Under Available Port Types, select OrderProcess.PurchaseOrderPT, and then click Next.

  6. On the Port Binding screen, under Port direction of communication, select I'll always be sending messages on this port.

  7. Under Port binding, select Dynamic, and then click Next.

  8. Click Finish.

Add a Send shape to the Decide shape

  1. Under BizTalk Orchestrations in the Toolbox, drag a Send shape to the Orchestration Designer. Place it below the ApprovalRequired shape.

  2. Right-click the Send shape, and then click Properties Window

  3. Type CreateApprovalTask in the Name field.

  4. Select Message_Task for the Message property.

  5. Select SendToTasksList.PurchaseOrderOperation.Request for the Operation property. This will tie the port to the Send shape in the Orchestration Designer.

In this procedure you add an Expression shape to your solution which assigns the Tasks path value to a variable. This procedure illustrates how to add logic to an orchestration to modify the properties of a dynamic send port.

Create a new expression

  1. Under BizTalk Orchestrations in the Toolbox, drag an Expression shape before the CreateApprovalTask Send shape.

  2. Right-click the Expression shape, and then click Properties Window.

  3. Type SetPortDestination in the Name field.

  4. Click the Expression property field, and then click the ellipsis () button.

  5. In the BizTalk Expression Editor, type the following:

    SendToTasksList(Microsoft.XLANGs.BaseTypes.Address) = "wss://localhost/sites/WSSAdapterWalkthrough/Lists/Tasks/";
    
  6. Click OK.

In this procedure you add a Construct shape to the solution which will construct a new instance of a message type within the orchestration. This procedure illustrates how to create a new message that is a copy of the inbound message and then modify the context properties of the new message. This step is required because messages are immutable in BizTalk; that is, once you have constructed it, you cannot modify the original.

Add a Construct Shape

  1. Under BizTalk Orchestrations in the Toolbox, drag a Construct Message shape before the SetPortDestination Expression shape.

  2. Right-click the Construct Message shape, and then click Properties Window.

  3. Type ConstructTaskMessagein the Name field.

  4. Select Message_Task for the Messages Constructed property.

  5. Under BizTalk Orchestrations in the Toolbox, drag a Message Assignment shape into the ConstructTaskMessageConstruct Message shape.

  6. In the Properties Window, type InitTaskMessage in the Name field.

  7. Click the Expression property field, and then click the ellipsis () button.

  8. In the BizTalk Expression Editor, type or copy the following:

    Message_Task = Message_PO;
    Message_Task(WSS.ConfigOverwrite) = "no";
    Message_Task(WSS.ConfigNamespaceAliases)= "orchns='http://OrderProcess.PurchaseOrder'";
    Message_Task(WSS.ConfigPropertiesXml) = "<ConfigPropertiesXml><PropertyName1>Title</PropertyName1><PropertySource1>Approve %XPATH=//orchns:PurchaseOrder/orchns:PurchaseOrderID%</PropertySource1><PropertyName3>Status</PropertyName3><PropertySource3>Not Started</PropertySource3><PropertyName4>Priority</PropertyName4><PropertySource4>(1) High</PropertySource4></ConfigPropertiesXml>";
    
    ImportantImportant
    These values supplied for these context properties are case sensitive. When setting configuration values for a dynamic port with context properties you must ensure that you use the proper case or an error will occur when BizTalk attempts to route the document to the designated send port.

  9. Click OK.

  10. Click File, and then click Save All.

In this procedure you build and deploy the BizTalk project. This step is required to create and deploy the assembly that BizTalk Server uses at runtime.

Build and deploy the solution

  1. Click Build, and then click Build OrderProcess.

  2. Click Build, and then click Deploy OrderProcess.

  3. Close Microsoft Visual Studio.

In this procedure you modify the existing receive location and send port to use XML processing for the pipelines. The receive XML pipeline persists message properties used during orchestration processing and the send XML pipeline persists the message properties that were applied in the orchestration which are subsequently used for message routing.

Modify the receive location

  1. Click Start, point to All Programs, point to Microsoft BizTalk Server 2010, and then click BizTalk Server Administration.

  2. Expand Microsoft BizTalk Server 2010 Administration SnapIn, expand BizTalk Group, expand Applications, expand BizTalk Application 1, and then click the Receive Locations node.

  3. Right-click SourceLocation, and then click Properties.

  4. In the Receive Location Properties dialog box, under General, select XMLReceive for the Receive pipeline property.

  5. Click OK.

Modify the send port

  1. Click the Send Ports node.

  2. Right-click SendToDestination, and then click Properties.

  3. In the Send Port Properties dialog box, under General, select XMLTransmit for the Send pipeline property.

  4. Select the Filters tab.

  5. Select the existing condition, press DELETE, and then click OK.

Start a new send port

  1. Click the Send Ports node.

  2. Right-click OrderProcess_1.0.0.0_OrderProcess.MyCompanyOrderProcess_SendToTasksList_<GUID>, and then click Start.

noteNote
You may have to refresh the console if this is not visible.

In this procedure you bind the orchestration to the specified ports. This procedure is required to tie physical ports to the orchestration that you built and deployed.

Bind the orchestration

  1. In the BizTalk Server Administration console, click the Orchestrations node.

  2. Right-click the OrderProcess.MyCompanyOrderProcessing orchestration, and then click Properties.

  3. Select the Bindings tab.

  4. Under Host, select BizTalkServerApplication in the Host field.

  5. Under Bindings, select FromSource for the ReceivePurchaseOrder Inbound Logical Port.

  6. Under Bindings, select SendToDestination for the SendPurchaseOrder Outbound Logical Port.

  7. Click OK.

  8. Right click OrderProcess.MyCompanyOrderProcessing orchestration, and then click Start.

In this procedure you create an InfoPath form and upload it to the Windows SharePoint Services Web site. The Windows SharePoint Services adapter will take that message, archive it in the Archive document library, and then send it to the Destination document library. During the processing of this message, Windows SharePoint Services context properties will be accessed that help determine the destination.

Create an InfoPath form to send through the system

  1. Open a Web browser and navigate to the URL of the site you created. For example, http://<server_name>/sites/WSSAdapterWalkthrough.

  2. In the Quick Launch menu, click InfoPathSolutions.

  3. Click the PurchaseOrder file to display the File Download dialog box, and then click Open. InfoPath will load the form.

  4. In the Purchase Order ID field, type 1003.

  5. In the Bill To field, type John Doe.

  6. In the Amount field, type 1750.

  7. In the Purchase Order Date field, type 1/3/2005.

  8. Click Save.

  9. In the Save As dialog box, type http://<server_name>/sites/WSSAdapterWalkthrough/Sourcein the file name field, and then press ENTER.

  10. Type PurchaseOrder3.xml in the file name field, and then click Save.

  11. Close InfoPath.

  12. In the Web browser, click Documents and Lists.

  13. Under Document Libraries, click Destination.

  14. In the Destination document library, you will now see your message listed in this library. You will also find a copy archived in the Archive document library.

  15. Click Home.

  16. Under Lists, click Tasks.

  17. In the Tasks list you will see the newly created approval task.

noteNote
Since the amount of the purchase order was over $1,000.00, the task was created.

In this walkthrough you have seen how to access the Windows SharePoint Services context properties and how to determine the destination of messages going through dynamic ports.
