Hi André,
many thanks for your thought's, but my requirement is not so complex and
difficult like it could be.
DAV (or WebDAV), in itself, stands for Distributed Authoring and Versioning. It
was originally designed mainly
as a tool to help people to remotely edit the HTML pages of a website, and be
able to do so using the same
HTTP connection which is already used by the website itself (thus avoiding
separate connections via FTP, SFTP,
SCP etc. and the corresponding user access and permissions setup).
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.
Parallel access for writing will be solved with a simple
locking mechanism, because it is relatively seldom, that more than one person
work on the same item and then it is acceptable,
that the first owner blocks the file til he is ready.
At least I have tried a little bit around to make our client (written in Java)
able to send DAV request, but this failed til now,
because it seems, that I have to write my own ' DavURLConnection', because the
'HttpURLConnection' can't handle the
additional requests. 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.
To get the data and edit them, it is very strait forward and works fine for me
:-)
Many thanks for your patience
Arno
