A webserver hosts the web applications like servlets and jsp
whereas an application server can take care of both the middleware i.e EJBs and jsp .

My point of view:
The best example of pure Web Server is Apache. You can also use another definition as HTTP server or Web Container which serves using HTTP methods (mostly GET and POST).
Application server is a set of containers:
- jsp/servlet container ( Tomcat has both:web and jsp/servlet containers);
- EJB , JMS, JMX containers (JBoss for instance);
WebLogic App Server has Web, EJB, JMX and JMX containers.
App Server is like a set of services with useful admin console and some useful features as load balancing, transaction, authentication and authorazation.
Tell me if I wrong.
Oleg.

From my point of view:
* static contents are distributed by web server (e.g. Apache)
* dynamic contents are distributed by application server
Servlets/jsps/ejbs etc. J2EE stuff are in the application tier.
