Brad, Works perfect. As noted my error was copying the whole base web.xml and making that change in it and using it. Using your version where just that one node is included and changed worked perfectly. Thanks for this... Next I need to update my Dockerfile process, but I am sure this is going to work. Really like blazegraph.... coming from some other triple stores and really seem to resonate with this one.
