Re: WO-Java Client Newbie Question

Thanks for these great pointers.   It's meant a
rethink to my application but I am clearer in how this
all works.   Hopefully its just a case of working
through this framework, and reapplying it to my own
app.   The framework's source is also a helpful
reference well  -- Especially since Google returns  a
whole 2 hits on "JCAuthentication" (One of which is
Apple's online docs)

Anyway, thanks for taking the time to reply.
