Please tell me how to create webdav client

[Takuya Matsuhira]

HI.
I am Takuya Matsuhira.
(I am not good at English.)

I am tring to create webdav client using jackrabbit api.
And I will use some jface class like WebTreeContentProvider and
WebTreeLabelProvider.
But I cannot  resolve setInput value.
(Maybe File class using File.listRoots)

I read the Website http://wiki.apache.org/jackrabbit/WebDAV .
But I cannot resolve my trouble.

So,would you tell me how to make webdav client using
this method ?

Souce which I am creating is below.
