I would accept nothing less of a full JDK running version 1.3.1 or higher. The enhanced personal edition with limited swing is fine and dandy for Applets but nothing serious in the world of real programming with Java. Tomcat won't run without a full JDK, and version 5 will require a minimum of JDK v1.4. There are many programs which will not run without a minimum of JRE version 1.3 due to the enhances in Applets that use Swing and high level RMI controls. The Java personal edition is nice, don't get me wrong, but I have a need for a full JDK.
