check out:
http://serverwatch.internet.com

specifically:
http://serverwatch.internet.com/appservers.html
http://serverwatch.internet.com/webservers.html

the differences are between webservers and appservers in general.  WebServers are used to present html to clients.. thats it.  For scripting you need to add external modules/plugins etc.  Application Servers facilitate providing dynamic content and handle transactions for you among other things.  For a Web Application you will need a webserver to deliver the content to the browser and the webserver will communicate with the application server to get the dynamic content.

There are NO webservers that support JSP and Servlets, you have to get a webserver separate like Apache/IIS/Sambar etc. and send all jsp/servlet requests to a servlet engine like Tomcat/Resin/Orion/JRUN etc.  Now alot of servlet engine companies know that their engine cannot run without a webserver so they bundle it with its own webserver like JRUN comes with a webserver (but you still have a WEBSERVER and APPSERVER), Websphere also comes with own modified version of apache web server.

But most App servers are configured to run with a webserver.  You can configure Resin/Orion/Tomcat etc to run with IIS or Apache or most web servers.

This question has been abandoned. I will make a recommendation to the
moderators on its resolution in a week or two. I appreciate any comments
that would help me to make a recommendation.
<note>
   In the absence of responses, I will recommend DELETE unless it is clear
   to me that it has value as a PAQ.  Silence = you don't care
