    Hello Prasad,

    Can you tell me the difference between application server and web server clearly with an example?

    • July 17, 2015 at 12:09 pm

      Inside a web server application server will be there. For example, consider your whole college as a web server and your class room as a application server. If somebody wants to reach you, first they need to each the collage and then they reach you classroom.

    Hi Prasad, I am a bit confused here. In the comment above, it is mentioned “inside a web server, app server will be there”. As per my understanding, i think a web server resides in app server. Ex. tomcat is integral part of JBoss app server. Please correct me if I am wrong.

      Hi Namratha, apologies for late reply. tomcat is a servlet container, which is part of jboss application server.

      Hi Kannan,

      JBoss is a Application Server because it serves J2EE Applications and Java Web Applications with and without Servlets (ie. EAR’s, WAR’s).
      Tomcat is a Servlet container, which means that serves Java Web Applications with and without Servlets, it cannot serve a J2EE application (EAR).
      Web Server – Serves html only (with Apache http you can even serve php with a php plugin).

      Hope this helps you.

    Hi Prasad,

    Myself and my friend were benefited by this site immensely. We are Test Automation Professionals having a thought to explore more and deliver it to everyone through a website like what you have presented beautifully here.

    But we don’t have any idea where to start from and how to go ahead with this.

    Need your inputs to create a website, hosting etc..

    Any small help will be very much appreciated. awaiting your reply.
