When running http://www.webdav.org/neon/litmus/, I had 500 webdav server errors my first hunch was to look if there was a newer webdav-servlet, so I proposed an upgrade to 2.0.1
turned out it didn't solve my problem. even worse, is webdav-servlet not giving me any logs in jboss (i've tried setting to DEBUG, ... but webdav-servlet is silent, modeshape is also DEBUG but not giving enough clue)
i will try to fix the problem if when i revisit it it's still there (as I need the security). what I know is that on ModeShape 2.6.0.Beta2 if webdav-servlet is protected under jboss container security it pretty much 500 error on everything. without the security, i can upload files and list but not creating dirs/collections.
