Question

As I understand it should be natively available in Jackrabbit 1.6 (I’ve found this blog entry http://dev.day.com/microsling/content/blogs/main/jrnativehttp.html) but I can not find any example configuration.

Answer 1

As the mentioned article points out (link added):

Anyway, to check it out run the
Jackrabbit 1.6 standalone server and
find the description and some examples
at
http://localhost:8080/webdav-jcr.jsp

If you don’t use the standalone server, you can use the Jackrabbit war distribution. The standard web.xml is already configured to expose the JCR-over-webdav remoting at /server, eg.

http://localhost:8080/server

See the JCRWebdavServer servlet config in the web.xml, using JcrRemotingServlet with batch read/write (actually implemented and documented in the super class with the same name):

            Defines how a missing authorization header should be handled.
            1) If this init-param is missing, a 401 response is generated.
            This is suiteable for clients (eg. webdav clients) for which
            sending a proper authorization header is not possible if the
            server never sent a 401.
            2) If this init-param is present with an empty value,
            null-credentials are returned, thus forcing an null login
            on the repository.
            3) If this init-param has a 'user:password' value, the respective
            simple credentials are generated.
