During server startup, the MessageBrokerServlet should be initialized and you
could enabled Debug level logging in your services-config.xml to verify.
Once the web app is running, before making any requests for a *.mxml file, try
making a request to one of your endpoints directly; start with a channel
endpoint URL from your services-config.xml file, replace any tokens (i.e.
{server.name}) with actual values, and request it directly in a browser. You
should get back an empty 200 OK.
Once you have that working, then proceed with further debugging of the
FlexMxmlServlet.

Subject: [flexcoders] Re: RemoteObject connections over HTTPS fails..
Hi Seth,
Till now we have used Flex SDK2.0.1. And we are now trying to
migrate to Flex SDK3.0.0. ( As we were having issues in enabling
access to our app on https and also we would like to use new features
in Flex 3 like ADG).
We have tried the Flex3 SDK Version (3.0.0.447) with BlazeDS
3.0.0.544) and here is the web.xml we have got..

i have downloaded the Flex_j2EE module from the Link
http://flexorg.wip3.adobe.com/modules/FlexModule_j2ee.zip and copied
the JARS to /WEB-INF/lib
When i checked the web.xml that is in the samples provided by BlazeDS
all i see is the MessageBrokerServlet in web.xml. But we wanted the
autogeneration of SWF Files when a request is made for *.mxml Files..
Appreciate your help..
Thanks
Mars

How do you have these servlets configured in web.xml?
