ArcGIS Server API For Flex 安全沙箱问题

<?xml version="1.0" encoding="UTF-8"?>   
<!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>

 

 

 

将此内容保存为crossdomain.xml,crossdomain.xml文件必须放置在域的根目录处,以tomcat为例,文件需放置在webapps\ROOT 下,IIS则放在C:\inetpub\wwwroot.

 

由于arcgis 9.3 server同样是以REST方式发布服务,所以当需要允许外域访问arcgis 服务时，同样需要设置跨域

crossdomain.xml放置的目录是{arcgis安装目录}\ArcGIS\java\web_output

PS:

补充下，在调试时layer.InitializationFailure.Message提示的是

A security exception occurred wile trying to connect to the rest endpoint make sure you hava a cross domain policy file acailable at the root for your server that allows for requests from this application

希望对刚开始学silverlight API的同学有帮助
