Thats the same approach im using. I have a commons-logging.properties and a
log4j.properties file in my WEB-INF\classes directory. But I only get the same
loggin as before in stdout.log Im using Win2k as OS. Where do my defined log
files go? Im confused. Everything compiles.
I have this line in my classes:
--------------------------------------------------------
private static final Logger zLogger = Logger.getLogger("MYCLASSNAME.CLASS");
Logging like this:
--------------------------------------------------------
zLogger.debug("New Session Was Created");
commons-logging.properties file has 1 line.
--------------------------------------------------------
org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger
log4j.properties file is here:
--------------------------------------------------------
log4j.rootLogger=DEBUG, stdout, nycbbuilder_log
log4j.appender.stdout=org.apache.log4j.RollingFileAppender
log4j.appender.stdout.File=catalina.out
log4j.appender.stdout.MaxFileSize=100KB
log4j.appender.stdout.MaxBackupIndex=2
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
log4j.appender.nycbbuilder_log=org.apache.log4j.RollingFileAppender
log4j.appender.nycbbuilder_log.File=nycbbuilder.log
log4j.appender.nycbbuilder_log.MaxFileSize=100KB
log4j.appender.nycbbuilder_log.MaxBackupIndex=2
log4j.appender.nycbbuilder_log.layout=org.apache.log4j.PatternLayout
log4j.appender.nycbbuilder_log.layout.ConversionPattern=%d{ABSOLUTE} - %p %c -
%m%n

Subject: Re: log4j best practices
I just implemented this over the weekend.
Still not totally sure what I am doing, but I do have all my classes
outputting to a log file I have specified. I went with a simple approach
creating a reference to a Logger object in each class (I have an external
properties file supplying all the config options). My problem is
everything ends up in one giant file and it is hard to interpret.
I am now thinking about having each class create and configure a logger
object and write to its own file. One log per class.
The good thing is it is log4j is easy to set up and start logging with.
Here is the tutorial I got started with:
