System Requirements

• Any operating system that supports the Java SDK environment.

• Java SDK 1.4.x and J2EE SDK 1.3.x (necessary only for the Messenger examples in chapter 6) must be installed.

• Hard disk, CPU, and RAM are dependent on the operating system and depend on how resource- intensive Java is on the specific operating system. In addition to those requirements, about 200 MB of hard disk space is required for all of the sources.
