Re: What Application Server are you using?

More or less.

Tomcat, JBoss, Glassfish, etc. are all applications to the Unix 
environment.  (Or whatever environment/OS you run.)

But in the parlance of web programming, your application is the thing 
that a client sees in their web browser.  Both JBoss and Tomcat at least 
(and probably all other containers) are capable of running more than one 
application as a separate virtual host.  Exactly like Apache is capable 
of running separate websites as virtual hosts.

It's really a quibble over semantics.  You could call a Java Enterprise 
Edition container a framework, but the entry point for the OS is the 
container itself, and the app runs as a series of callbacks. 
"Container" is just JEE parlance for the thing that does that work for 
you (processes incoming request, sends a response, connects to a DB, 
etc.) which conforms to their JEE specification of what a container does.

In the same way we call a database a database even though it's really an 
application too, we have different names for different specific types of 
applications: demon, shell, name server, etc.  Container is just one of 
those names.
