Step 6: Generate .4gl stub to access the .NET library

Use the fglwsdl tool to generate the client stub to access the BarcodeService, as follows:

$ fglwsdl http://localhost/BarCodeService.asmx?WSDL

This will create two .4gl files, which must be compiled and linked into your BDL application in order to call the .NET barcode library functions. These files contain the BDL interface to access the .NET library where you will find the function buildImage, defined in BDL.

In the final step we modify the existing application, Step 7: Modify your BDL application.
