The Idea behind this App is that the written XML files are landing directly into your Axway directorys.

So in order you have to define this directory pathes for MMD and Payload. Please compaire your values in document 'parse_vars.php' with your absolute paths on your Axway Machine (The Folderstructure for Variables $mmd_file_path, $xml_file_path must exist and case sensitive correct). Please refer to your connectivity test message values you create with the ebXML Colleagues for production environment.

Make shure that PHP User have proper rights to write in your choosen directory. Ownership can also be a problem.

If the paths are correct and your PHP User is able to write files in destinated folders for MMD and Payload, then have a look at your Web Server Logs/Filesystem Logs.

Even if this all above not work, change the PHP Logging to default. To accomplish that, just search for error_reporting(0) and uncomment this Log Level by adding two Slashes in Front.

Dont forget to delete the uncommenting, after finding the root cause. Because I use several Vars who are not global and indeed are not initialized. PHP will remind you everytime about it.

Everything will work, but it looks horrible...
