    JSP, SERVLETS AND BEANS


    I want to know what are the differences between JSP and Servlet, when is best
    to use JSP and when servlet is. I heard that JSP is as HTML code, that calls
    to Bean's functions that return Strings,
    that included in the HTML code is the Final Page. Otherwise I heard that
    Servlet's return is Java Server Page, and I know well how to use them but
    I don't know what's diference.

    Thanks.

    Re: JSP, SERVLETS AND BEANS

    At its most simple level JSP is an easy to read/code version of a servlet
    but is more suited to your presentation layer, it is cleaner because it is
    based on tags like ASP is, servlets are the equivalent of CGI and are a wee
    bit more powerful than JSP pages - JSPs become a servlet when it is
    compiled (typically the first time it is requested by a browser). Both
    servlets and JSP return data to a presentation media like a web browser.
    Beans are used to encapsulate your business logic so you dont stick it in
    your JSP pages.

    Definately worth buying a book on this .... good one below.

    1) in jsp we embedded all the scriptlet code inside HTML tag,
    where as in Servlet it is the other way(you can create a dynamic page inside
    the methods).

    2) JSP pages, while compliation makes a servlet automatically.

    3) On the server where the application is hosted( if it is shared server),
    there is a possible chance of misuse of code by the authorities. where as
    in Servlet you keep only .class(dot class) file so no code will be visible
    or misused.

    4) In JSP there are inbuild objects,where as in Servlet every thing should
    be invoked.

    5) Excution time is more in case Servlets.

    6) during development any change of code in JSP does't need compliation.
    Where as in servlet you need to complie and make class file every time.
