I just have a look in the Adaptor source, followed the
WebObjectsRDocumentRoot value in the code to find that it is finally
"used" in Adaptor/transaction.c  during the call tr_handleRequest with
:  app.docroot = docroot; 
app.docroot isn't used to build the response as far as I can see.

Also you can start your app with WOApplicationBaseURL and
WOFrameworksBaseURL to set a different location (non standard) for the
WebServerResources of your application. so how the adaptor would handle
that ?  it can't...

so WebObjectsDocumentRoot is useless but I still have it in
webobjects.conf to /var/www/www.mydomainname.tld  as the adaptor tries
to set it. (it just need to be set to something)
(WebObjectsAlias still being important)


But in order to fix the "ERROR/NOT_FOUND" problem you have to look on
WebObjects server side (not in Apache):
In the
$NEXT_ROOT/Local/Library/WebObjects/Applications/MySchool.woa/Contents/WebServerResources/
you need to have basicbrain.gif or any other resources.
If not the application will generate html response with ERROR/NO_FOUND
in the src URL which of course cause au 404 error for the http GET at
the apache level.

I hope this help

Aurelien


ps: I have made a documentation about the adaptor installation in
French, it is available there:
