Question

我收到了StackOverflow错误，所以我想在stackoverflow中询问。

Send failed
Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 500: url: 'http://localhost:8080/context/messagebroker/amf'

当你输入messagebroker servlet url：

时会出现这种情况

HTTP 500 -

Answer 1

但是当我输入这个问题时，我发现它是什么......我对应用程序作用域上声明的全局对象有一个循环引用。这是一个意想不到的复制粘贴......所以当messagebroker/amf发射时，它被卡在循环引用上，一遍又一遍地对同一个对象进行实例化。我要离开帖子以防其他人遇到此错误，因为谷歌没有多大帮助。

为目标“destinationName”实例化“className”类型的应用程序作用域实例时出错
