    Java Enterprise And Standard Edition


    Hi All

    I am newbie to Java. I download a Java Enterprise edition and build some
    Java code but discover that the Enterprise edition holds no javac command
    to compile. Discover this when I tried to compile a .java file and was unsuccessful.

    I was wondering what is the difference between an Enterprise to a standard
    edition such that when I try to compile and execute a .java file, I can't
    do so in an enterprise edition. How then is Enterprise edition being used
    in a java environment??? Does it need a java standard edition?

    rgds,
    Saiful

    Re: Java Enterprise And Standard Edition

    Hi
    The java standard edition (J2SE) and the java enterprise edition
    (J2EE) work together. Basically:

    J2SE gives you the core system, the standard run time classes and
    APIs/ packages, these are in one jar file - rt.jar It also include the
    development tools javac/ jdb/ javah etc. There is also the JRE, this
    is only the runtime system without any development tools - aimed at
    installation on client machines.

    J2EE is a collection of commonly used packages for enterprise
    programming - EJB/ Servlet/ JSP etc. You could download all of these
    separately and install them on your system but J2EE eases this by
    making them all available in one jar file - j2ee.jar In addition the
    J2EE set of technology includes a testing environment application that
    can play the role of CORBA ORB, EJB Application Server, Web Server,
    Servlet/ JSP Engine etc. This is called j2ee (lower case) and can be
    run from the command line

    Just to help with the confusion, the term J2EE means one of three
    things depending on where it is used: a) the catch all description of
    the technology set as in "I am developing a J2EE application" b) the
    technology set you download from Sun and c) the application supplied
    within the technology for testing (j2ee - lowercase)

    For your development you should install J2SE and J2EE on the machine

    hi Saiful,

    The Java Enterprise edition is nothing but a set of APIs which can be used
    in the distributed computing environment. The Standard Edition or the SDK
    contains core Java API along with the standard tools like the java compiler.
    So you will first require the SDK on your system. Use this as base to build
    applications using the Enterprise edition.
