Session activities (login, logout, timed out, login failed).

会话活动(登录、注销、超时、登录失败)。

Notice that login failed for user "(in other words, no login name is specified)."

注意，登录失败的原因是user ' '(换句话说，没有指定登录名)。

As an example, our login page displayed an "invalid login" message if login failed.

举例来说，如果登录失败，那么登录页面将显示一条“invalid login”消息。

If you are getting a "Login failed" message, it is possible that the server is not started yet.

如果您看到一个“登陆失败”的消息，很可能是服务器还没启动。

We've also added a message (the text surrounded by the JSP ICONS) to show the user that the login failed.

我们已经添加了一条消息(jsp图标边上的文本)来显示登录失败的用户信息。
