I remember using 
this one in the past, but now I don't even both running the web container through Eclipse.  I do my development with 
Resin, which I find easier to work with than Tomcat.  (Yes, they have an open source version).  I develop on windows, I just put a shortcut to the Resin httpd.exe in my quick launch toolbar in windows.  I just click the icon to start it, and close the console window to stop it.  That seems the easiest to me, and since I use 
Freemarker instead of JSP, i have no need for JSP debugging.
