RE: Problems with Slide Client and SAP Portal WebDAV

So I've been attempting to see what's different about the SAP Portal
WebDAV response vs the Slide Server response. Here's a few observations:

1) Notice that the "xmlns:D=DAV:" is excluded from <D:response> in SAP
Portal's WebDAV.  Could this make the slide client upset? 

SAP Portal
==========
<D:multistatus xmlns:D="DAV:">
   <D:response>
      <D:href>
            /irj/go/km/docs/documents/
      </D:href>
      <D:propstat>
         <D:prop>
            <D:displayname>
            </D:displayname>
         </D:prop>
         <D:status>
               HTTP/1.1 404 Not Found
         </D:status>
      </D:propstat>
   </D:response>
.....

----------
Slide
=====
<D:multistatus xmlns:D="DAV:">
   <D:response xmlns:D="DAV:">
      <D:href>
            /slide/
      </D:href>
      <D:propstat>
         <D:prop>
            <D:displayname>
            </D:displayname>
         </D:prop>
         <D:status>
               HTTP/1.1 200 OK
         </D:status>
      </D:propstat>
   </D:response>
.....


2) For collections, D:displayname isn't well populated in SAP Portal.
I've re-created this specific scenario in my local Slide server and all
seems ok.

3) HTTP Header is slightly different wrt Multi-Status indicator. My gut
says this difference is not important.  I doubt the HTTP header is that
key to parsing the Response XML and population of higher level classes.

Slide
=====
<<<<<<< from server  ---------------------------------------------------
HTTP/1.1 207 Multi-Status

SAP Portal
==========
<<<<<<< from server  ---------------------------------------------------
HTTP/1.1 207 Unknown


I've been attempting to trace the PROPFIND code in the slide client
without any definitive identification of problem code area.
Unfortunately, I don't have access to the SAP Portal WebDAV server from
my Eclipse environment.  Otherwise, troubleshooting this issue might be
somewhat easier.

Assuming the debug XML info from Slide client is accurate, then I've yet
to find any other differences between SAP Portal and Slide WebDAV
servers.

I attached 3 text files that contain debug output of slide cmdline
client.

I'm running JDK 1.4.2_13 on Win2k.  I explicitly set JAVA_HOME and PATH
(only contained %JAVA_HOME%\bin) just to minimize outside influenes.

Slide1a.txt and Slide1b.txt are the outputs of ls and ls -l against top
level collection.

Slide2.txt shows the 403/security weirdness against a child resource of
root.  I checked again with Windows Explorer and it shows the 3 XML
files and "Commercial Laundry" and doesn't show any of 403 responses.

To answer a related response, I'm using 2.1 binaries off Jakarta
download site.  I will likely pursue building library myself, as well.
Eclipse and I seem to be getting along. ;-)

The WebDAV stack in SAP's Portal KM returns 403 in multistatus if the
resource exists, but you don't have permission to get the properties. 
*Most* WebDAV clients simply do not display these resources.

So I would propose you collect a few examples (XML response and what the
Slide client makes out of it), and then we could investigate what's
going on (and decide whether it's by design, whether the client could be
enhanced, or whether it may be a bug in the server).
