Microsoft Word, OpenOffice.org, Mac OS X, Desktop Linux distros and lots of other software already know how to read/write files from DAV shares with no special (additional) software such as you describe. Notably, Microsoft Windows explorer makes a complete mess of the specification and prohibits the use of obviously-useful features, making DAV nearly impossible to use without help. I have turned to South River Technologies' WebDrive[1] software to make our DAV shares work on Microsoft Windows versions after Windows 7. It mounts a WebDAV share as a drive-letter and then you just work with the files as if they were local. - -chris [1] I have no interest in WebDrive other than I am a very satisfied customer. -BEGIN PGP SIGNATURE- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJYJgfFAAoJEBzwKT+lPKRYl4cP/AznYDHuH4wNYjfi6pvfUqT8 KCj2aI+bcd01dcIgyhhPopRuz4qGW4YVQ6+uqNYq8avvwTCmpj0h5g5bwG0ZPi/I ZneYvZc9SR7ZL10vPAVM38KKe+y+7guOoiLPWgST/nTKmFGXi26JdezZaq1R/xk6 B30RHQw/pzd9c0BvrhyhDlGOQoGZVsim0wl3JjufZNwTVb6QE193NhFmew5fz9P3 gyrZsVy16KuqQI7k/QDs/PKIZJKEW0Rv+Q0lXJTuiTQmQNNh/AcL4sd11LISsbx3 v6hSklGz2HapXLFNtIgHlnjI9xzG1cMndxzr9nKJM0xpBF1Z69hpCePTMXzX66rw CJL3bsfUuOXuu+9h5yY8QlJoNcCrxesG6n8c3nPA6GKNc+UHh/DN7DI9ZKv3rthr kHhx3rI5N873pgzAMScmzX48MJ1wQ16xJIlVFh6eGXLdemXr6hSsJghmNV5WlCDk bct3829iQTG3jQJSufgBTKojY5lYywE5Z1fGDUbPZeWm5m1Za0pnILMho7GVY3N1 u5AveOGP8uIXl5yczOpxnVKf3UTS/qByca3VB81U/6TdG6lDMV8al0m1S1+FBgCU oNulgTrDATKYw7DH8SW0PkVgZDFvWQRFG/W3POrUmsIxwUoQ1mN+3OXRaZ3bqyNo T7vvGzCzQzvdopDPk+G0 =vaGE -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

DAV (or WebDAV), in itself, stands for Distributed Authoring and Versioning.

But in itself, DAV does not have all the features which are needed to do this in a safe, multi-user scenario. It is a big internal and 15 year old webserver, where I want to implement exactly this purpose, what you are talking about. DAV should be used instead of share's, like it is today. This service is only used internally and will never become a public service, so from the security site I have no such strange requirements.

Do you know, if some Java library for DAV clients exist. I haven't found any lightweight solution til now. Search Google for "java library PUT request", it seems to provide several links.
