x4juli is a port of the main parts of log4j to the J2SE Logging API. The default implementation is incomplete and therefore still not widely used, even when introduced in J2SE 1.4. x4juli provides logmanagers, formatters, handlers, and filters to fill the gap. The interface and use of the original API has not been changed. Additionally, x4juli delivers a native implementation of the Jakarta Commons Logging (JCL) API and the Simple Logging Facade for Java (SLF4J) API.

JChav is a way to see the change in performance of your Web application over time by running a benchmark test for each build you produce.

If integrated with cruise-control or similar build tools, you will get an idea if the changes you are making to your Web application are improving or degrading performance.
