webserver contains web container only but application server contains both web container and ejb container
ex:tomcat is a webserver
weblogic,websphere,Jboss are application server

A computer that delivers (serves up) Web pages. Every Web server has an IP address and possibly a domain name.

Also called an appserver. A program that handles all application operations between users and an organization's backend business applications or databases. Application servers are typically used for complex transaction-based applications. To support high-end needs, an application server has to have built-in redundancy, monitors for high-availability, high-performance distributed application services and support for complex database access.

Hi Friends,

Webserver serves pages for viewing in web browser, application server provides exposes businness logic for client applications through various protocols.


Webserver exclusively handles http requests.Application server serves bussiness logic to application programs through any number of protocols.

Webserver delegation model is fairly simple,when the request comes into the webserver,it simply passes the request to the program best able to handle it(Server side program). It may not support transactions and database connection pooling.
