There are a whole lot of logging frameworks out there. Log4j is one of the most popular ones. I prefer the "successor" of log4j: slf4j with the logback implementation. Slf4j separates the api from the actual implementation and can be used in conjunction with log4j. Log4j, slf4j and logback are all made by Ceki Gülcü.
