Projects / Just4Log


Just4Log is a library to dynamically enhance the performance of various Java logging systems inside a Java application. The source code in Java is not modified, but the optimization occurs on the compiled bytecode files. It optimizes bytecode from Log4j, Apache Commons, and JDK 1.4 java.util.logging. It can also automatically add "enter" and "exit" logs at every exit and entry point of methods. An Ant task offers integration in Ant scripts.
