[Mapserver-users] arcims emulation and arcexplorer

[Ed McNierney]

Paul -

I have looked EXTREMELY closely.  I have removed, for example,
"superfluous" linefeeds from my XML.

What we really need is someone who has some familiarity with the ArcIMS
interface.

I don't think the Perl emulator works with ArcExplorer 4, does it?

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 :)
