Defining and Adding a new provider to the apache VFS api

[akapur <An...@sophia.inria.fr>]

Hi,

I am using apache VFS api to create a virtual data space for our software.

I need to know how to define and add a new provider to the api? I mean 
which classes do I need to extend and implement to create a new provider?

This provider does not depend upon any specific protocol.

Have a look at the VFS sandbox and e.g. the mime or webdav provider.

Base directory:
vfs\sandbox\src\main\java\org\apache\commons\vfs\provider

Simply checkout vfs from http://svn.apache.org/repos/asf/commons/proper/vfs/trunk to get access to it.

There you will also find a "vfs-providers.xml" which you have to provide to give VFS a clue where to find your provider and which namespace to use to access it.

Basically you have to provide implementations of
* AbstractFileObject (including the FileObject interface)
* AbstractFileSystem (including the FileSystem interface)
* AbstractOriginatingFileProvider (including the FileProvider interface)

When looking at the sandbox it sould become clear what to do. Unhappily there is no wiki which describes these steps in every detail.

Ciao,
Mario
