How to Consume Web Service Arrays
BizTalk Server provides the ability to consume arrays that are exposed in Web services from a BizTalk Orchestration.
To configure an Orchestration to consume an array exposed in a Web service:
Determine the URL for the Web service that exposes arrays. This is typically an asmx Web page that lists the operations supported by the Web service. For example: http://localhost/ArrayWS/ArraySvc.asmx.
Add a Web reference to this URL in the Visual Studio project that contains your orchestration:
In the Solution Explorer, right-click References, and click Add Service Reference.
In the Add Service Reference dialog box, click Advanced.
In the Service Reference Settings dialog box, click Add Web Reference in the Compatibility section.
In the Add Web Reference dialog box, enter the URL for the Web service into the URL text box and then click Go.
Enter a name for the Web reference into the Web reference name text box and click the Add Reference button.
The Web reference will appear under Web References in the Solution Explorer.
Once you have a Web reference added to the project, the Add Web Reference command is directly available when you right-click the project name or References or Web References.
Add a Web port to your orchestration:
Drag a Port shape from the toolbox to one of the port surfaces in the Orchestration Designer to launch the Port Configuration Wizard. Click the Next button in the Port Configuration Wizard to display the Port Properties dialog.
Enter a value into the Name text box to identify the port, and click the Next button to display the Select a Port Type dialog.
Select the option to Use an existing Port Type, select the Web Port type that corresponds to the Web reference you added, and click the Next button to display the Port Binding dialog.
In the Port Binding dialog select the appropriate Port binding option and click the Next button, then click the Finish button. You should now have a Web port displayed in the Orchestration Designer that includes the operations supported by the Web service.
Add Send and Receive shapes to your Orchestration as appropriate:
Drag a Send shape from the toolbox to a connecting line in the Orchestration Designer surface to configure the orchestration to send a request message to the Web port. If you connect the Send shape to one of the Web port request message connectors, BizTalk will automatically create a message of the appropriate type to be used when sending a request message to this port.
Drag a Receive shape from the toolbox to a connecting line in the Orchestration Designer surface to configure the orchestration to receive a response message from the Web port. If you connect the Receive shape to one of the Web port response message connectors, BizTalk will automatically create a message of the appropriate type to be used when receiving a response message from this port.
Use the SOAP Adapter to send messages to or receive messages from a Web service. For more information about configuring the SOAP Adapter see Configuring the SOAP Adapter.
The BizTalk Server Orchestration Engine provides support for consuming both one dimensional and jagged arrays that are exposed by Web services. If you add a Web reference to a Web service that exposes arrays, the Orchestration Designer will generate a Web message type that describes the array. You can then send and receive messages of this type like any other message. BizTalk Server does not limit the sending of Web messages containing arrays to only Web ports.
