Your confusion possibly arises because there are at least 2 types of logger
that you might mean, and 3 main choices for one of those at the moment,
although one of those 3 is deprecated and a second is probably becoming less
popular.
OK I'll take a quick stab and see if this gets you anywhere in the right
direction.
You mention two distinct types of logging. The 1st is the "hit" logging
which is very similar to what you would get from apache httpd. This simply
logs each incoming request. This is achieved by adding a <Valve> to your
%catalina_home%\conf\server.xml - you can embed it inside the <Host></Host>,
<Engine></Engine> or <Context></Context> tags, but for your purposes, just
shove it in the engine for now. It looks a bit like this:
<Engine blah blah>
<Valve
className="org.apache.catalina.valves.FastCommonAccessLogValve"
directory="logs" prefix="ao_access_log_" suffix=".log"
pattern="common" resolveHosts="false"/>
</Engine>
You can tweak the path, filename, and the pattern that defines each line -
see
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/valve.html
for details. Leave resolveHosts set "false" to speed up performance.
Not that my example above is from my own 5.5.9 server - ISTR 5.0 config
syntax is different - check the doc link above for the detail.
The 2nd part of your logging is where you write your own messages to a
logfile. I did that as follows:
java.util.logging.Logger logger =
java.util.logging.Logger.getLogger("logname");
logger.setLevel(logLevel);
fh = new FileHandler(logFilePath, maxLogFileSize, logFileCount, true);
fh.setFormatter(new AoLogFormatter(logFileDateTimePattern));
logger.addHandler(fh);
Then to write a log message you can just do this:
log("Write this to the log");
and it will write the log file to logFilePath
See the java.util.logging.Logger javadocs for more details.
This is very basic. Much more spophistication can be achieved through
config files.
