You can use the "run on server" menu option if you're using the WTP plugin supplied with the j2EE spin of Eclipse.
Personally, I loathe WTP - it's far too limiting, So I install the sysdeo Tomcat plugin. Sysdeo adds 3 toolbar buttons and associated menu options, one to start Tomcat, one to stop Tomcat and one to restart (start/stop).
Experience keeps a dear School, but Fools will learn in no other.
