Because this crossdomain.xml should be on the server were my Flex client is placed, isn't it? I have read some articles, and they say that this XML has to be placed on the server which offers the web service. I think this cannot be possible, in that case I have to ask to my IT department to upload that file, and they for sure aren't going to allow that.
Could you please help me? Why is the client working under Flex Builder and not when I deploy it on my Tomcat? And when I says deploy I mean that I have copied what Flex Builder generates on "bin-release" folder into the Tomcat's webapps folder.
