<p>Has anybody any useful links that can be used to consume a web service using flex?
The easier the solution the better</p>

<p>Thanks</p>

I found
this tutorial
pretty helpful - it gives clear examples of consuming a basic webservice, with code on both sides (server and flex).
One thing to remember when accessing remote webservices on a remote server from flex is the need for a
crossdomain.xml
- the security model in flex needs to be explicitly told to be allowed access a service from a remote domain.
