Subject Re: runtime modification to log

Other than cloning? ;)

I've updated the FAQ with four questions and answers:

- Why can't Log4J find my configuration file in a J2EE application?
- Can Log4J automatically reload my configuration files?
- (my stuff) Why do I get ugly messages from the NT Event Viewer when using
the NTEventLogAppender?
- Why can't the NT EventLogAppender dynamically change category messages?

If I see any other commonly-asked questions, I'll update the FAQ.

How about putting this in the header and footer of the mailing list
messages?

- Questions? We have answers!  Check the Log4J FAQ:

Hopefully that might cut down on some of the emails.

Hi Chris,

Tell me about it. Do you have a suggestion in mind?  Ceki
