Subject Re: logging + tomcat (4.1.24,Linux)
Date Wed, 25 Jun 2003 11:28:43 GMT
When I use commons-logging - I ignore the loggers provided by tomcat. (Its 
because I haven't read how to marry the two together) A problem of the tomcat 
loggers is it is a boolean - you log or your don't. This is an issue when you 
include many debug and trace calls. You don't want them logged unless you are 
debugging. (But you also don't want to remove those statements either)

So in my situation  - I ignore the tomcat-loggers (almost), and use the 
config settings for my logging implementation (In particular, log4j).

Someday - I'll learn how to configure log4j to shove its log entries back 
into the tomcat loggers and still get the flexibility to choose logging level 
by package (or class)
