Logging from a servlet in Tomcat

["Dr. Evil" <dr...@sidereal.kz>]

I have a question: It would be extremely useful for a servlet to be
able to record debugging messages in some way.  I don't have a Java
debugger, but I could do a lot of debugging if I had a command that
looked like this:

log("We are in this part of the code now");

I have seen documentation for a command like that, and I have tried it
in my installation of Tomcat 4.0, but it doesn't send any output
anywhere, so it seems useless.  Is there a way to get it to work?

Thanks

By default, log output from your servlets goes to a file in the "logs"
directory.  You can change where it goes by setting up a <Logger> element
to do what you want.  Configuration information is included in Tomcat's
download, or available online at:

  http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/logger.html
