java - 由于运行时异常，MessageBrokerServlet 初始化失败

Question

我的应用程序在 Windows 和 Mac 上运行良好，但是当我将完全相同的 JBoss 文件夹复制到 Debian(或 CentOS)时，我无法弄清楚发生了什么。

经过一些研究，我发现有些问题，因为如果我尝试访问 /MyApp/messagebroker/amf，我会收到 404 错误，而不是空白页。

我有 MyApp.ear，里面有 blazeds.war，但显然，Linux 没有执行部署 BlazeDS。

JDK版本怎么样——与windows/Mac环境相同吗？此链接可能有帮助:http://www.liferay.com/community/forums/-/message_boards/message/4619030
