No problem, I think I might have read a little too much into your original post too :)
I was thinking that you were looking for a more complex solution, but wildcards are sufficient for most needs, especially if your namespace is /. I think there is an exception that does get thrown when no action is mapped to the request. I am testing it right now and I don't see an exception in my app server console, but it does show a stack trace. I'd have to look in the code to be sure. Anyhow, if wildcards work, you're in good shape! -Wes On Sat, 2008-11-08 at 17:13 -0800, delsvr wrote: > Thanks for the quick reply. > > I may have spoken too soon about the wildcard mapping.
