It's been a while since I've had time to play around with Java.  My last go of it I was using some version of Eclipse, JBOSS, Tomcat and IBM WebSphere 5.0.  I decided today to put up an updated version of that environment and see how things have changed.  My plan is to run with Tomcat 5.5, Eclipse 3.01 and Sun's JDK 1.5.0.
