New to JackRabbit ..

Dear All,

    I m new to JackRabbit. I would like to webdav enable my webapps which currently serves a web document management system and the webdav feature would be an added feature. Pls do refer http://docs.zoho.com

    This is my setup do guide me in case I m wrong ,

    1) Wrote a WebDAVServlet extending SimpleWebdavServlet and implemented the getRepository method which bears the FirstHops.java code as mentioned in the jackrabbit home.
    2) an entry in webdav make for accessing the WebdavServlet done !!
    3) Tried to access the servlet thru the Linux webdav client cadaver as below,
        
    Observations ::
    
    1) as soon as the server is started a repository is created with repository.xml in the same directory. Also the default workspace and security workspaces are created. 

    
[test@localhost ~]$ cadaver http://localhost:8080/webdav
Authentication required for Jackrabbit Webdav Server on server `localhost':
Username: test
Password:
Could not open collection:
500 Internal Server Error
dav:/webdav/? 

    I also get this exception ..

I have no exact idea about this error, but from looking at the code
[1], it seems the repository instance used by the webdav servlet is
null. Maybe there are other errors in the log before that indicate
some problem with the repository startup...
