    Multi-tier or 3-tier architectures compel separation between business logic, presentation logic and database logic. Few important benefits are detailed over here:

    Manageability: Every tier can be upgraded, monitored or tuned independently & different duties could be assigned to different tiers.
    Scalability: More hardware could get added up and also permits the clustering that is horizontal scaling.
    Maintainability: Up gradation or other changes are performed ...

    Client tier presents Java, Web browser, or other applications like WAP phone, Applet etc. A request is sent to the Web server by the Client tier. Request is then forwarded to JSP or Servlet, or returns static content in case it is in Web server.

    Presentation tier summarizes the presentation logic that is required for server clients. A JSP or Servlet present in presentation tier intercepts requests of clients, manages logons, or sessions. Business services are being accessed and finally ...

    The J2EE platform comprises of J2EE services, protocols, components and (API) Application Programming Interfaces. Functionality is being provided by J2EE to develop distributed and multi-tiered Web based applications. A J2EE component is considered to be a functional and self contained software unit which has been assembled to J2EE application, along with related files and classes, to do communication with other components. Following components are present in J2EE.
