Paul,
Let me see if I can break it down into something I can send you. This started happening when I went to add spring @Transaction support to one of my resource methods. I've since backed all that back out and still happening. It's going to be something simple I am overlooking...
Just so I understand. I should be able to @Scope("singleton") if I use HttpServletRequest as a parameter to my method using @Context? If I would like to have req be a class variable then, I'll need @Scope("request").
I'll keep digging and see what I can figure out.
