Some more detailed information on this - the issue is
that the IIS connector doesn't handle the ;jsessionid token in URLs unless it
appears after the query string. The J2EE servlet spec does not specify
that this token has to appear after the ? symbol and thus many other
app servers handle it just fine. How this arises in the first place for
remoting requests is that the CF bridge to the Flash Remoting gateway asks the
servlet response to encode the URL and checks to see if it was decorated with a
;jsessionid token (it would do so if it thought the client couldn't handle
cookies). e.g. http://www.yourserver.com/yourapp/flashservices/gateway;jsessionid=XXXX
If the encoded URL did include a ;jessionid then an AMF
response header is sent back to the NetServices client to tell it to append the
;jsessionid token to the gateway URL on the next request. You can see this
AppendToGatewayUrl response header in the NCD. From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Theodore E Patrick Sent: Thursday, May 19, 2005 7:58 AM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Web Services and CF7 Dave, Awesome, thanks for

There are two basic ways for Flex to
invoke back-end ColdFusion CFCs, SOAP (Web Services) or AMF (Flash Remoting). My
app had been using SOAP, but I needed to convert to AMF (the performance
difference is significant). Last year Brandon Purcell wrote an
excellent blog entry entitled Switching between webservices and Flash Remoting using Flex , and
so I used his steps to make the switch. As he notes in that entry, ColdFusion
variables returned via SOAP have their names converted to uppercase, whereas
variables returned via AMF retain their original case, and so any binding code
(or Flex code referencing returned data) needs to be converted from all caps to
actual case. The converted code worked perfectly
for CFC methods returning queries, they ran exactly as they did before, just a
whole lot quicker. But my CFC methods returning structures all failed, none of
my bindings and client-side code worked. The problem? Waldo Smeets figured
this one out, unlike returned queries, returned structure members are all caps,
even when using AMF. This is horribly inconsistent, and hopefully it'll be fixed
in the future. For now, keep this in mind. Yahoo! Groups Links
