webapp and NFS file path

I have a working opensuse 12.3 NFS server with opensuse 12.3 working clients.
The networkfolder is /exports/renderfarm and this folder is connected by every nfs-client (Yast) to /home/user/nfs

How can I tell the webapp brender where the webapp brender clients can find /exports/renderfarm or nfs
If I fill in network files paths /exports/renderfarm in the webapp brender under new project then clients cannot find the files
and when typing network files path /nfs then the webapp cannot find the right nfs folder because its looking in root.

I hope I'm clear enough or I'd love to hear it


greetings
Anton
