hi philip the changes commited with rev. 331281 modified the default locator-factory inside the simple webdav application. consequently its now required to indicate a workspace which you want to access the repository with. in contrast to the jcr server servlet there is currently no 'root' node available with http://localhost/jackrabbit-server/repository/, so you have to connect to the workspace directely.
see also: http://www.mail-archive.com/jackrabbit-dev@incubator.apache.org/msg03304.html section "additional changes in the simple-server" i think, this explains the problem you expirenced. kind regards angela
