Problems with Log4j, Eclipse, Tomcat

I’m in the process of setting up the environment for my new web application. When I tried to install and use log4j logging in my project, nothing worked! I use Eclipse and the Sysdeo Tomcat plugin to start Tomcat, and placing my log4j jar in various locations throughout the server proved to have no effect.

The problem was that I had selected the option for Sysdeo Tomcat to provide my Eclipse project’s library information to the Tomcat classpath. Commons-logging then had a collision with Log4j. My solution was to remove commons-logging from my application classpath within Eclipse. When I deploy this application, there may be more to say about this issue.
