Updated Tomcat and Log4J tips

[Geoff <mi...@sprynet.com>]

I have updated my Tomcat and Log4J tips to document how to use Log4J version 
1.3 as a daily rolling log file with Tomcat 5.x. The URL is:

	http://www.minaret.biz/tips/log4j.html

The new features in Log4J 1.3 will make the DatedFileAppender I wrote for 
version 1.2 obsolete ( http://minaret.biz/tips/datedFileAppender.html ). 
Great work everyone!

There does not appear to be a way to set the internal logging level of Log4J 
1.3 in a configuration file. There is a way to set debug mode and to turn 
off all error messages but I can't stop the INFO messages that are filling 
up my "catalina.out" file without turning off error messages as well.

Perhaps I'm missing something here. If not, what would be ideal would be to 
replace the "debug" attribute in the Log4J configuration file with an 
attribute that sets the internal log level for Log4J to whatever level you 
like. The INFO messages are interesting for a little while but once 
everything is working, I would rather not see them.

Best,

Geoff

That should be very helpful in getting people up to speed with 1.3.  Thanks!

Well, actually, Log4j uses itself for logging (well, UGLI, but Log4j 
implements UGLI).  As such, if you want to turn off logging for Log4j, then 
do it in your config file....

     <logger name="org.apache.log4j">
         <level value="OFF"/>
     </logger>

Note that LogLog is currently being used to output some extra stuff 
temporarily (at least it was the last source I built).  This will be 
removed before 1.3 final, so any stuff that isn't getting turned off by the 
above config in the 1.3 alpha/beta releases, will certainly be turned off 
in 1.3 final.

It's arguable.  Doing it using the <logger> is natural,. but since Log4j 
logging is a special case, an "internal" attribute (or some such name) 
might be good to have as an alias to <logger name="org.apache.log4j">.
