问题描述

在开始开发程序之前，我正在尝试使我的应用程序国际化，以便以后对它进行扩展更容易.

Im trying to internationalize my application before I get started in developing so its easier for me to expand it later.

尽管我尝试遵循这些教程，但我总是遇到相同的错误:我的xhtml中的标签无法解析，好像没有消息一样(即使Eclipse自动完成了它们也是如此).

However as much as I try to follow tutorials, I always get the same error: the tags in my xhtml fail to be parsed, as if the massage did not even exist (even though Eclipse auto-completes them).

堆栈跟踪的摘要如下(此处是Pastebin的完整堆栈跟踪):

The summary of the stacktrace is as follows (Here for the full stacktrace at Pastebin):

Type Exception Report

Message /index.xhtml @11,50 value="#{msg.['title.index']}" Failed to parse the expression [#{msg.['title.index']}]

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

推荐答案

我非常相信将#{msg.['title.index']}"更改为#{msg['title.index']}"(删除.)会很有帮助

I'm very confident that changing #{msg.['title.index']}" to #{msg['title.index']}" (removing the .) helps a lot
