How to: Convert a Text Document to XML and Route to a File Location Using an Itinerary Routing Slip
Goal
The section demonstrates how to create a pipeline that will convert a text document to XML and then select the appropriate itinerary and route the message to a FILE location.
In this How-to topic, you will complete the following steps:
Use a pipeline to receive a flat file document and convert it to XML.
Configure the Itinerary Selector pipeline component to resolve the appropriate routing slip.
Create an on-ramp that uses the custom pipeline.
Test itinerary-based routing of a flat file message.
Prerequisites
The procedures in this How-to topic require the completion of the Prerequisites for the Development Activities.
Before You Begin
Complete the following tasks before you perform the steps later in this How-to topic:
Deploy the DataFormatTransformation itinerary.
Create the test message.
The following procedures describe how to do each of these.
To deploy the DataFormatTransformation itinerary
In Visual Studio, open C:\Projects\Microsoft.Practices.ESB\Source\Samples\DataFormatTransformation\DataFormatTransformation.sln.
In Solution Explorer, in the Itinerary.Library project, double-click DataFormatTransformation.itinerary to open it in the Itinerary Designer.
In Visual Studio, click the design surface of DataFormatTransformation.itinerary. In the DataFormatTransformation.itinerary Properties window, configure the following properties:
In the Itinerary Status drop-down list, click Deployed.
In the Model Exporter drop-down list, click Database Itinerary Exporter.
Click the ellipsis button (...) next to the Itinerary Database property.
In the Connection Properties dialog box, choose the SQL Server that hosts the itinerary repository database, and then specify the name of the database (the default name is EsbItineraryDb).
Save all project artifacts.
In Visual Studio, right-click the design surface of the DataModelTransformation itinerary, and then click Export Model.
To create the receive pipeline
In Visual Studio, right-click DataFormatTransformation.Schemas, and then click Properties. Click Application, and then type GlobalBank.ESB.DataFormatTransformation.Schemas in the Assembly name box.
Right-click DataFormatTransformation.Schemas, and then click Properties. Click Signing, and then verify that the Sign the assembly check box is selected and that the assembly location points to .\..\..\..\..\..\keys\Microsoft.Practices.ESB.snk.
Right-click DataFormatTransformation.Pipelines, and then click Remove.
Right-click DataFormatTransformation, point to Add, and then click New Project. Click Biztalk Projects, and then click Empty Biztalk Server Project. In the Name box, type DataFormatTransformationReceive.Pipeline.
Right-click DataFormatTransformationReceive.Pipeline, and then click Properties. Click Signing, and then verify that the Sign the assembly check box is selected and that the assembly location points to C:\projects\Microsoft.Practices.ESB\keys\Microsoft.Practices.ESB.snk.
Right-click DataFormatTransformationReceive.Pipeline, point to Add, and then click New Item.
In the Add New Item dialog box, click Receive Pipeline in the Templates pane. In the Name box, type ItinerarySelectReceiveFF, and then click Add.
Right-click References for the DataFormatTransformationReceive.Pipeline project, and then click Add Reference. Click the Projects tab, and then click DataFormatTransformation.Schemas. Click OK to add the reference.
From the Toolbox, drag a Flat file disassembler pipeline component to the Disassemble stage of the pipeline.
In the Properties window for the flat file disassemble, click DataModelTransformation.Schemas.NAOrderDocFF in the Document schema drop-down list.
From the Toolbox, drag an ESB Itinerary Selector pipeline component to the Resolve Party stage of the pipeline.
From the Toolbox, drag an ESB Dispatcher pipeline component to the Resolve Party stage of the pipeline, and then place it under the ESB Itinerary Selector pipeline component.
Save all project artifacts.
To create the test message
Click once in the NAOrderDocFF.xsd schema file of the DataFormatTransformation.Schemas project. In the Properties pane of Visual Studio, change the following two properties:
Generate Instance Output Type. Click the drop-down list for this property to change it to Native.
Output Instance Filename. Click the ellipsis button (…) for this property and accept the default path of C:\Projects\Microsoft.Practices.ESB\Source\Samples\DataFormatTransformation. In the File name box, type NAOrderDocFF, and then click Save.
Right-click NAOrderDocFF.xsd under DataFormatTransformation.Schemas, and then click Generate Instance. At this point, you should have a new file generated in the C:\Projects\Microsoft.Practices.ESB\Source\Samples\DataFormatTransformation directory.
Copy (do not move) the file NAOrderDocFF.txt from C:\Projects\Microsoft.Practices.ESB\Source\Samples\DataFormatTransformation to C:\HowTos.
Note
This is the message you will receive and convert to XML. This document represents a flat file version of North American Order document.
Steps
To deploy the receive pipeline and the schema
Right-click DataFormatTransformationReceive.Pipeline, and then click Properties. Click Deployment, and then type Microsoft.Practices.ESB in the Application Name box.
Right-click the DataFormatTransformation.Schemas project, and then click Properties. Click Deployment, and then type Microsoft.Practices.ESB in the Application Name box.
Close the Properties panes for both DataFormatTransformationReceive.Pipeline and DataFormatTransformation.Schemas.
In Solution Explorer, right-click the DataFormatTransformation project, and then click Deploy Solution.
To create and configure an ESB on-ramp
Click Start on the taskbar, point to All Programs, point to BizTalk Server, and then click BizTalk Server Administration.
In the BizTalk Server Administration Console, expand BizTalk Group, expand Applications, and then click Microsoft.Practices.ESB.
Right-click Receive Locations, point to New, and then click One-way Receive Location.
In the Select a Receive Port dialog box, click OnRamp.Itinerary, and then click OK.
In the Receive Location Properties dialog box, in the Name box, type OnRamp.Itinerary.FlatFile.FILE.
In the Type drop-down list, click FILE, and then click Configure.
In the FILE Transport Properties dialog box, in the Receive Folder box, type C:\HowTos\DropFolder.
In the FILE Transport Properties dialog box, in the File mask box, type *.txt, and then click OK.
To configure the Itinerary Selector pipeline component
In the Receive Location Properties dialog box, click ItinerarySelectReceiveFF in the Receive pipeline drop down list, and then click the ellipsis button (...).
Use the Configure Pipeline dialog box to configure the following Itinerary Selector component properties:
Click the ItineraryFactKey property, and then type Resolver.Itinerary.
Click the ResolverConnectionString property, type ITINERARY:\\name=DataFormatTransformation; and then click OK.
Click OK to close the Receive Location Properties dialog box.
In the BizTalk Server Administration Console, right-click the OnRamp.Itinerary.FlatFile.FILE receive location, and then click Enable.
To test itinerary-based routing of a flat file message
In Windows Explorer, browse to C:\HowTos.
Copy (do not move) NAOrderDocFF.txt to C:\HowTos\DropFolder.
Browse to C:\HowTos\Out. Verify that the DFT%MessageID%.xml message has been written to the directory.
In the BizTalk Server Administration Console, right-click the OnRamp.Itinerary.FlatFile.FILE receive location, and then click Disable.
After the OnRamp.Itinerary.FlatFile.FILE receive location is disabled, right-click it, and then click Delete. In the Confirm delete receive location dialog box, click Yes.
