2.10) Select Simple inbound Flat File service to read from a local file, click Next.
2.11) Use the default values on the Flat File service name screen and click Next.
2.12) Now the CWYFF_FlatFile project is imported to the workspace. On the Business object and directory screen, select the Customer Business object and the input directory. Click Next.
2.13) Select Other as the input format and select the CSVDataHandler
2.14) Use "\n" as the file split delimiter, click Next.
2.15) Select the local archive directory, click Finish.
2.16) The FlatFileExport interface is now added to the Assemble Diagram.
2.17) Right click the SimpleFileModule and select New - External Service to add a Simple outbound Flat File service to write to a local file, click Next.
2.18) Use the default values on the Flat File service name screen and click Next.
2.19) On the Business object and directory screen, select the Customer Business object and the output directory, click Next.
2.20) Set the output file to Customer.xml and use other default values on the Output file name screen, click Next.
2.21) Select XML output format, click Finish.
2.22) The FlatFileImport interface is now added to the Assemble Diagram.
2.23) Drag and drop a Mediation Flow from the Assemble Diagram Palette to the Assemble Diagram editor.
2.24) Name the Mediation Flow to SimpleFileFlow
2.25) Double click the SimpleFileFlow and click Yes on the confirmation message box.
2.26) Use the default value on the Generate Implementation screen and click OK.
2.27) Now the SimpleFileFlow editor is open.
2.28) Click the Add an interface link and select FlatFileExport.
2.29) Click the Add a reference link and select FlatFileImport.
2.30) Save changes.
2.31) Click the emit link from FlatFileExport, then select Operation Map.
2.32) Select the default values on the Select Reference Operation screen, click OK.
2.33) The Mediation Flow Request editor is open.

2.37) Link the emitInput and the createInput with a Move transformation.
2.38) Save all changes and back to the Assemble Diagram editor, link the FlatFileExport to SimpleFileFlow, then SimpleFileFlow to FlatFileImport, save changes.
Step 3 - Testing the module
To run the module, right click the local Process Server and select Add and Remove Projects.
Then add the SimpleFileModuleApp to the Configured projects list, and click Finish.
Start the Process Server, and check the SimpleFileModuleApp is started and synchronized.
Copy a CSV file to the input directory, the file should have a format as shown in below
Peter,20
Tom,21
Emma,22
Julia,23
After a few seconds, the application reads the input CSV file and output few output XML files to the output directory, the input file is archived to the archive directory with a .success or .fail extension. The generated XML file has a format as shown in below.
<?xml version="1.0" encoding="UTF-8"?>
<p:Customer xsi:type="p:Customer" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
