Deployed Applications can't access file system

Hi, my webobjects/wonder app needs to access/create files/directories in a directory of the server where it runs. When I debug in eclipse the application on my powerbook it works correctly but once installed on the server I get the message below. I assume that the applications runs as _appserver so, In Workgroup Manager, I added this user to the group who has access to this directory. but still does not works.

Any advice ? Is there any special procedures in Java or WebObjects to access files ?

PS: I know there are spaces in the name but these are escaped and work properly when executed locally on my portable. PPS: I'm new to this part of Java io...
