GSWeb and resources in app bundle

[Johannes Fortmann]

First off, sorry if this is the wrong list; I couldn't find a 
gsweb-specific list.

I'm trying to build a little demo app with gsweb. I'm working on OS X 
10.3, and so far everything has been working quite nicely, except for 
one big thing: I can't access any resources of my app.
Specifically, my app resides at 
/Library/WebServer/Documents/WebObjects/Test.woa.
I'm trying to access a file named enigma.png residing at 
Test.woa/Contents/Resources/enigma.png.

Now, as far as I understood, there are two different possibilities for 
sending the resource:
1. binding to the data property, then implementing a method that 
returns the image data. This works.
2. binding to the filename property, and returning a file name.

Now, if I bind to the filename, the resulting webpage references my 
image as /WebObjects/Test.woa/Contents/Resources/enigma.png . Accessing 
this file gives me a blank page, even though the file should be there 
(my document root is /Library/WebServer/Documents/).

Do I have to set specific permissions, or anything? Am I doing anything 
totally stupid?
Please note: I may be blissfully ignorant of anything... this is the 
first time I did any web programming.

Greetings,
