1.flex访问跨域的ArcGIS Server服务出现了安全沙箱错误，运行的时候出不来地图，
?需要在远程的Web服务器根目录下放置一个“crossdomain.xml”安全策略文件

<?xml version="1.0" ?>

<!DOCTYPE cross-domain-policy SYSTEM
 "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd" >

<cross-domain-policy>
    <site-control permitted-cross-domain-policies="all" />
    <allow-access-from domain="*" />
    <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

?

安全策略文件需要被放到特定的位置
ArcGIS Server for .Net应该是IIS的根目录（如：C:Inetpubwwwroot）
ArcGIS Server for Java应该是web_output目录（如：C:ProgramFilesArcGISjavaweb_output）

?

2.MXML.XML文件

<?xml version="1.0" encoding="utf-8"?>
