Flex与java通过socket进行交互出现安全沙箱问题
用java写的服务端代码，用flex写的客户端代码，是做一个曲线图的实时效果。flex发送连接，java端接收到套接字，则不停的sleep数据，想数据以json格式返回给flex，flex解开json数据，将数据绑定lineChart组件，实现实时刷新。
以上过程一切正常OK。当我以为一切都好的时候，大问题来了。
我把flex下面的bin-debug目录全部拷贝到我的java的web工程（真正要部署到服务器上的程序）下面,然后用html的object标签去调用bin-debug目录里面的.swf文件。启动tomcat,访问页面，报安全沙箱错误。界面出来了，但是没有数据，连接中断（数据肯定没有问题，flex单独和java交互的时候已经验证了这一点，只是拷贝到web工程下面才报的）。
我的解决方法1.
在tomcat的Root目录下面放crossdomain.xml文件。
里面的内容是
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd";>
<cross-domain-policy>
<allow-access-from domain="*" secure="false"/>
</cross-domain-policy>
但是此方法还是不行。
以下是我的代码，跪求帮忙

以上都是我未加安全策略的代码，因为我加了也不行。在这里请教大家乐，大家可以在我代码上面加东西，告诉我该怎么做。诚心求助，谢谢

socket的安全沙箱错误 网上找下需要特殊的配置。不是简单的在tomcat下方策略文件。
