Please tell me the Difference between web server, web container and application server.
A web container is the component of a web server that interacts with Java servlets. A web container manages the life cycle of servlets; it maps a URL to a particular servlet while ensuring that the requester has relevant access-rights.
In Layman terms : A web Server means: Handling HTTP requests (usually from browsers). A Servlet Container (e.g. Tomcat) means: It can handle servlets & JSP. An Application Server (e.g. GlassFish) means: *It can manage Java EE applications (usually both servlet/JSP and EJBs).
Apache Tomcat server: Apache Tomcat is a web container. It allows the users to run Servlet and JAVA Server Pages that are based on the web-applications. It can be used as the HTTP server. The performance of the Tomcat server is not as good as the designated web server.
The difference between a Server and a Web server is that the server is a central vault where computer programs and data are stored and gotten to by the customers in the network, while a Web Server is a PC program or a PC that runs the application. Web server examples are: Resin. Apache Tomcat.
