How To Upload/Download Files in WDP from KM

Hi folks,

I'm developing an Web Dynpro application for Portal and using a upload and download component.

I'd like to use the KM as a file repository. How can I send and get those files to/from KM application in Portal?

Using: SAP Studio 2.0.9 SP9 (WDP), SAP WebAS 6.40.

By the way, is it possible to send those files to mobile/pda using MI Client?

Regards,

Rogerio
