Hi,
     I am using webdav for accessing an application deployed in JBoss. Basically the application is working fine with MS Office webdav. I am able to view the folders, files,etc. I am trying to access the application through windows explorer webdav. I am able to login and see all the folders and files. But each time I try opening a MS Office file (Excel, Word or ppt), I am getting the login screen again asking for credentials.

Is there any work around for this?


Thanks and Regards
Satyajit

We also are getting this. We can cancel the dialog (sometimes having to do so twice) and get in to the directories. This is a significant point of confusion with our users.

I am using windows XP.

I am facing one more problem may be some extension to this issue. When ever I try to open a MS Office file from windows explorer webdav, login credentials are asked. If I give the credentials the document doesn't open (gets stuck). Is it any way related to above problem?

Any help is highly appreciated.

Satyajit,

You need to configure everything correctly. When prompted for a login the application is not properly configured. Consult the installation manual and verify all aspects are correctly set.

In Windows Explorer webDAV and MS office webDAV I am using the same application URL. This application is perfectly working in MS Office WebDAV. When it comes to windows explorer this issue arises of MS Office document getting stuck. Is it related to windows installation(any dll files or something) and any other issue?

Hi Satyajit,

Microsoft has been so kind as to 'fork' their webdav client software between windows and office. So it is not a complete surprise, no. It means the Windows webdav client is not working correctly. What happens when you cancel away the authentication? Do you get thrown out?

HI,
If we cancels the authentication window it asks twice and then alerts couldn't download the file.

The problem is basically the inconsistency of opening of MS Office file that works fine in my machine using MS Office 2003 SP3 although it takes few seconds to open the file, but for users it doesn't and it get stuck and they use MS Office 2000 SP3.

Is it related to MS Office Version problem? or anything related to Application server?

Satyajit

It could be related to Office 2000 although to the best of my recollection I've seen this work with Office 2000. There is just not a huge client base still on that version or we'd hear of it more often I guess.

BTW: I'm just talking about DNN/DMX WebDAV of course, not a third party product.

Dear all,

I'd like to add my little contribution to this post. First of all, I experience the same issue as above while trying to map a DMX web folder in windows XP (Auth dialog continuously popping up). Instead, WebDAV works perfectly while opening the files from the web interface directly in Office (no auth problems and correctly save back to server).

From the HTTP trace below (sniffed with WireShark), I see that the client is requesting the URI '/' while the entire DNN website is installed on a virtual directory of the server. The address that I typed in the explorer dialog is 'http://extranet.gualaclos...portal2/dmxdav.axd', so as fire as I can understand, the 'OPTION' request should be directed to the '/portal2' URI. Obviously this is not happening and the web server throws the 405 error.

What do you think?

Regards,

Andrea

Dear all,
I found an answer to my question above in the following KB article:
http://support.microsoft.com/?kbid=831805

Due to another annoying bug in the Windows XP Webdav implementation, the client thinks that the root of the server is always WebDAV aware and hence issues the OPTIONS command, but the web server throws an error.

Hi Andrea,

The traces are very helpful indeed. I often use Fiddler to do the same thing.

About your observation: yes, this is a drawback of the WebDAV implementations of Windows (which, incidentally is not the same as that of Office). They expect the application to be able to go to the root. In the latest version I have advised people to configure their installation so that even '/' goes to DNN/DMX. But this will still not take care of an installation that is in a subdir of a site. My advice to anyone rolling out DNN/DMX with WebDAV is to use parent portals at all times. So instead of using http://www.mydomain.com/subsite, use http://subsite.mydomain.com. IMO it is also good practice to organize your sites like this.
