Subject Re: Why GlassFish

Johnny, you're having way too much fun :D .
Sam to answer your question, tomcat simply is the reference implementation
of servlet and jsp specification from Sun (and a damn fine one at that

Glassfish like other comparable app servers out there implement the JEE
specification (well whichever they are targeting) and as such they do much
more (as required by the spec).

Probably some confusion arises when you find that they can both do servlets
and jsp (web applications). This is because the app servers should provide
that feature.

So if you're looking to do ejb's a full blown app server would serve you
well. If you get by fine with just servlets+jsp+other frameworks thrown in
then tomcat is pretty suitable for you as well.
