Ok, got this figured out with the help of a co-worker.
I needed to use the Tomcat plug-in (we use the one from Sysdeo) to get this going. I mistakenly thought that by using the EE edition of Eclipse along with having the webtools plugins (WTP) all that was needed was in place. Not so.
The downloaded plug-in was extracted into the eclipse/plugins folder. Once that was done, Eclipse was restarted and the Tomcat references were in place on the menu, the preferences dialog box, and the projects' properties dialog box.
Hope this information will be of value to anyone experiencing the same problem.
