This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
The reason is that if the JVM trys to load a class not in a package, it looks in the "current" directory. In the servlet environment you have no control over the "current" directory, therefore ALL classes used in servlets MUST be in packages to avoid strange errors.
