We'd love to help, but we'd need to know a lot more of the specifics.
Have you tried this? If so, what did you try and where did you get stuck? Was there an error during deployment? If so, what was that error? Are you really trying to deploy just the WebDAV service without the repository? Or have you already deployed the repository successfully?
I need to create a standalone repository server and im thinking to use webdav or rest as interface to upload/move/get/delete document. I've already tried embeded but we need to put repository(document) server behind firewall. See Model 3 in http://jackrabbit.apache.org/deployment-models.html
