至於後端WebService
我是使用Java Apache Axis，以JWS的方式建置
連線的時候，要注意Flash Crossdomain Security
請自行參考相關文件，加上crossdomain.xml
嘗試錯誤的過程中~
覺得Flex 2.0 AS 3.0的設計實在有些奇怪
像是webservice.getOperation回傳型別
以及< mx : operation ..... >為什麼是小寫
還有WebService的Operation，都只能夠用getOperation取得
可是文件上明明就有從Operation建構子傳入ws的方式
但是就是無法成功執行動作~~
當然目前最大的問題就是相關文件相當缺乏
我這樣寫法也不知道是不是標準的做法
