Log4j

 

Log4j is an open source tool developed for putting log statements into your application. Developed by Apache's Jakarta Project.

 

Its speed and flexibility allows log statements to remain in shipped code while giving the user the ability to enable logging at runtime without modifying any of the application binary. All of this while not incurring a high performance cost.

 

One of the distinctive features of log4j is the notion of inheritance in loggers. Using a logger hierarchy it is possible to control which log statements are output at arbitrarily fine granularity but also great ease.

 

Inserting log statements into your code is a low-tech method for debugging it.

 

Why not just use the log4j package as written directly from People Code?

People Code supports Java objects and PeopleSoft delivers the log4j lib in the PS_HOME/class directory
