Look extremely closely at the XML you are sending back and the XML a
"real" IMS server sends back. Seemly trivial differences are actually
important. You can crash ArcMap sending it valid XML with a slightly
different <?xml version ?> header than it expects. There could be
something similar going on with AE.
(Note that AE2 speaks a completely different language altogether. :)
Ed, post your emulator code so that the rest of us can start hacking on
it :)
