我在Google App Enginge中使用Struts2。
在global.properties文件中，我有：
MESSAGE_SUBJECT = A user sent you a message.
在Struts.xml中，我有：
<constant name="struts.custom.i18n.resources" value="global" />
如果我有getText("MMESSAGE_SUBJECT");动作，我收到以下错误：
com.opensymphony.xwork2.util.logging.commons.CommonsLogger error: Could not reload resource bundles

错误仅在部署时发生，但在开发环境中，完全没有问题。
有什么想法吗？感谢。

Struts无权重新加载AppEngine
禁止的容器（Jetty）struts.properties中的更改 struts.i18n.reload =假
