From Coder's Log

Welcome To CodersLog, here you can find information about building high performance large scale java applications, some of my discoveries while working with VoIP, as well build scripts for junit/cobertura and others.

This site is mostly a collection of common code/configurations and other hard to find information.

NOTE :Some of these pages are not quite there yet, the titles are there to remind me about topics that I still have to cover.
