>>"lastly, what is an application/ web server???"
As far as I know, application server is able to handle more technologies (in J2EE) such as JMS, EJB and etc. While web server is used only to serve / control the static resources such as JSP, images, binary data and etc.
You might be interested to hear from other experts though.

Yes, a web-server is just meant for hosting web-resources like images, HTML files, etc. If you want to host JSP or ASPX or such pages (which require language-compilation, etc) you need some kind of plug-in or servlet-container with the web-server. An application server in turn can host entire applications and can be bundled up with a web-server, servlet-container, EJB-container, etc

>>what is an application/ web server
An application server must firstly be an application. So, it plays a role as operating system. The different is:
+The operating system works with hardware.
+Application server works with platform such as operating system, virtual machine.
To be like an OS, an application server is an environment to develop, deploy,run, manage the application on it.
Some famous application servers are JBoss (RedHat), BizTalk (Microsoft), BDE (Borland), Sun One (Sun), OCj4 (Oracle).

I am sorry I am going to tell about Web server but I have forgot.
To me,Web server is an server which implementation HTTP or HTTPS protocol.
It like a document store which contains static or dynamic documents.
Document can be located by URL.

yes, they both are frameworks. Frameworks help you in managing the flow of your application by separating the layers among application, controller and database. By separating the layers, there application will be loosely coupled and the changes in one of the layer will have least impact on another layer.
Struts has its own way to manage the flow of application and so does Spring. At the end, framework is used to produce the application that is maintaneable.
