或错误信息：
faultCode:Client.Error.MessageSend faultString:'Send failed' faultDetail:'Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 404: url: 'http://localhost:8080/WebContent/messagebroker/amf''
?
解决办法：
endpoint的问题，在services-config.xml文件中，由于此类型的endpoint：
<endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint"/>，中的{context.root}获取不到项目名称。
解决方法，选择项目，右键“Properties”-->“Flex Server”-->将Context root（浏览器访问时的上下文路径）的内容改为“/项目名称”，-->OK。
