KM Like Capabilities (Directory List) in WD ABAP

Hello,

I'm converting a project from WD Java to WD Abap and i've stumbled upon a problem that Im currently unable to resolve:

I know how to deal with uploading files, and I'm also aware of the quite difficult ACF Elements.

I do not understand however, how do I provide a capability that will allow me to list the files within a certain directory on the application server (beforehand this was the Java-KM server, now obviously in wd abap this needs to be the ABAP application server).

There's CL_GUI_FRONTEND_SERVICES-DIRECTORY_LIST but obviously it doesn't work in the contained wd-abap environment.

Am i supposed to script something? or does SAP provide a normal solution?

thanks everyone.
