Hi Marco,
I am also interested in how you organize your private folder where you keep
the resource/user/type information.
Well, my problem was that I had to enable users to watch files in a
document management system,
ROOT -
|
--- user ( as collection )
|
--- UrlEncoder.encode(path/to/resource)
( as collection )
where ROOT is the root path of your private directory ( collection ) .
The user collection has the same name as the username; I keep the
e-mail address as a property of the collection .
Each path has a property that says which type of subscriptions are
submitted for the current user.
Then, in my servlet, I create a listener on the ROOT directory, so
that I am notified of every change in the tree and I can operate with
subscribing & unsubscribing in the servlet itself. The system operates
in the directory ( never directly on webdav subscriptions ) : there is
only one class that minds about the callbacks.
More, internally ( in memory ) data is organized a little differently
than on disk : since you get the callback for the resource ( a path )
you need to organize data in maps that have
UrlEncoder.encode(path/to/resource) as key and the list of users
subscribed as data.
Another pit : I had ( on a tomcat based server ) to put the
initialization of the servlet ( reading the dav tree and so on ) in a
separate thread ... it was stopping the server for too long making
impossible for the webdav server to start up properly.
cheers
Marco
