Log4j Behaviour in Tomcat and WebSphere

Logging is the interface between developers and system admin. Developers need to know how their logging code behave in a server envrionment. Admins need to know how to configure and turn on/off logging. This series inspects how two most common logging methods, Java Util Logging and Log4j, behave in Tomcat and WebSphere.

Step-by-Step : How logging caused big performance problem for a JAX-WS web service

This article is about how a small piece of code can cause big performance trouble and how hard it is to figure out the root cause.

What's the Number 1 Java Coding Best Practice?

There are some common known Java coding best practices: use StringBuffer for string concatenation, don't create large objects, cache expensive objects such as DateFormatter, etc.. How important are they? How much performance can you improve by following these practices? 5%, 10%, or 20%?

Then, even the most dilligent developers can not claim that they follow all the best practices all the time, especially with so many 'new' frameworks and standards being adopted. Could you have missed anything?
