Customize Filename Dynamically

This tutorial shows how to customize output filename inside orchestration.

There are 5 tutorials in this training.

1. BizTalk Training 1 – basic send/receive xml message
2. BizTalk Training 2 – receive/send plain text
3. BizTalk Training 3 – customize filename dynamically
4. BizTalk Training 4 – using Functiods in Map
5. BizTalk Training 5 – using FTP Adapter

Objectives

• Learn how to change filename of the output file.

Prerequisites

• BizTalkTraining 2 project.
• Configuration on BizTalk Administration for BizTalkTraining application.

Topics

1. Add variable in the orchestration.
2. Add msgPerson2.
3. Add Message Assignment to the orchestration.
4. Test application.

Step-by-step

Suppose that I want to change name of outgoing file. As in training 2, the input filename is *.txt format but I want the outgoing message type as xml format and also add “output_” text before. E.g. incoming filename is “person1.txt”, outgoing filename will be “output_person1.xml”.

1. Add variable in the orchestration.
   • Open Orchestration1 in BizTalkTraining. (Project from BizTalk Training 2).
     
   • Switch to Orchestration View, right click on Variables and select New Variable.
     
   • Click on the variable.
     1. On Variable Property, change Identifier to “fileName”.
     2. Change Type to “string”.
        
   • Now you’ve add variable name “fileName” as string to the Orchestration1.
2. Add msgPerson2.
   • Create new Message on the orchestration name “msgPerson2” and set Message Type as the same as msgPerson (BizTalkTraining.FlatFilePersonSchema).
     
3. Add Message Assignment to the orchestration.
   • Drag Message Assignment from Toolbox to bottom of the Orchestration1.
     
   • Click on ConstructMessage_1 object. Notice that you highlights entire Construct Message object.
   • On Construct Message Properties, check msgPerson2 in Message Constructed and change Name to “Construct msgPerson2”.
     
   • Click on Message Assignment (the object inside Construct Message) and change Name to “Assign fileName” in Message Assignment Properties.
     
   • Double click on Message Assignment and fill in the code below and click OK.

     msgPerson2 = msgPerson;   fileName = msgPerson2(FILE.ReceivedFileName); fileName = System.IO.Path.GetFileName(fileName.Replace(".txt",".xml"));   msgPerson2(FILE.ReceivedFileName) = "output_" + fileName;

     msgPerson2 = msgPerson; fileName = msgPerson2(FILE.ReceivedFileName); fileName = System.IO.Path.GetFileName(fileName.Replace(".txt",".xml")); msgPerson2(FILE.ReceivedFileName) = "output_" + fileName;

     The code above assigns msgPerson to msgPerson2 and assigns incoming filename to “filename” variable, modify string and assign back to “msgPerson2”.
     

   • Add new send component to the bottom of the orchestration and change Message to “msgPerson”.
     
   • Create new send logical port.
     1. Right click on Port Surface area, select New Configured Port.
        
     2. Set name to “SendXMLPersonPort”.
     3. Set Port Type as following configurations.
        Port Type: Create a new Port Type
        Port Type Name: SendXMLPersonPortPortType
        Communication Pattern: One-Way
        Access Restrictions: Internal
        
     4. Set Port Binding as below.
        Port direction: I’ll always be sending messages on this port.
        Port binding: Specify Now.
        Transport: FILE
        URI: C:\FILE2\OUT\%SourceFileName%
        Send pipeline: XMLTransmit
        
   • Connect green button from Send component to SendXMLPersonPort.
     
   • Deploy the project.
     
4. Test the application.
   • Open BizTalk Administration and restart BizTalk host.
     
   • Refresh BizTalkTraining application.
     
   • Test application by copy person1.txt from C:\FILE2\person2.txt to C:\FILE2\IN.
     Note: You must any delete files in C:\FILE2\OUT before.
   • You’ll see output in C:\FILE2\OUT.
     
   • Person1.txt
     
   • Output_person1.xml

You can download the example source code (zip file) at here.
The zip file contains

• BizTalkTraining folder which is the example project on Visual Studio 2005.
• FILE2 folder which contains IN and OUT empty sub folders for test receive and send message and person1.txt which is an example text message.
• binding.xml file which is a configuration file for import in BizTalk Administration.
