Deploying Flex in Tomcat

Question

I've got a Flex application that I'd like to deploy as a
webpage. It works when I run it from Flex Builder, however, when I
deploy it on the Tomcat server on my machine, parts of it break.
The part that breaks is one of my buttons which uses HTTPService to
perform a Rest Post to another web service and fill a variable with
the result. It doesn't work on the deployed version and I can't
figure out why.
In order to deploy, I clicked the 'Export Release Button' and
then copied everything in the release folder to my tomcat folder. I
then navigate to the html page, and most of it works, just not the
part using HTTPService. Do I need to copy additional files or set
some security options? Thanks for any help, I'm almost done with
this first application.

Answer 1

Managed to resolve the issue. The problem was with not having
a crossdomain.xml which allows Flex to access and receive data from
other domains. To fix the problem I simply created a
crossdomain.xml (whose format can be found online easily enough)
and put it in the ROOT webapp folder of my tomcat directory.
