Check that you are calling the correct URL and if so, The error message (faultCode:Channel.Security.Error faultString:'Security error
accessing url' faultDetail:''Destination: DefaultHTTP') can occur because your Tomcat server might not contain that crossdomain.xml or the file has been copied in the correct location without restarting Tomcat server.
Another possibility is that you have a firewall that blocks crossdomain.xml from loading.
