well, some progress.
I don't get an error, Tomcat doesn't post the INFO messages on startup like it
used to (with its logger class?)
Any way, I made this basic little servlet from their example, but it gives me
an error about the package.
import org.apache.log4j.Logger;
import org.apache.log4j.BasicConfigurator;
public class Hello {
static Logger logger = Logger.getLogger(Hello.class);
public
static
void main(String argv[]) {
BasicConfigurator.configure();
logger.debug("Hello world.");
logger.info("What a beatiful day.");
}
}
besides not being able to resolve the symbol of Logger, it (the error) states
package org.apache.log4j does not exist.
Wonder what I'm missing there, if Tomcat can now see Log4j upon startup, but I
can't import the package?

That's a good sign. It means Log4j is being used. Have you put log4j.xml or
log4j.properties in common/classes? Make sure you define a root logger with
an appender. I would set the level to something like "warn" so you don't get
any debug or info messages from arbitrary loggers by default.
