    How good is CORBA?

    Hi everybody,

    i have been developing web based applications using python+cheetah.

    The numbers are increasing. The applications have many common parts of
    code. Though these applications are separate from each other they are
    run in the same server.

    I heard about CORBA... but also heard that it has some flaws...like
    the programming being very complicated.
    Also heard that CORBA is no more used these days...

    Can someone suggest me a better option or is corba fine?

    Thanks,
    Sai

      CORBA is good for what it is good for. It does take some time
      to get up to speed on it, but eventually most of it makes sense.
      Some of the language mappings, especially C++, can be hard to use
      safely, but the Python mapping is much easier to use.

      If you need good performance, multiple language support, multiple
      OS/hardware platform support, and preferably control both ends of
      the communication, CORBA may be for you. Check out omniORB for C++
      and Python (http://omniorb.sourceforge.net/), and JacORB for Java
      (http://www.jacorb.org/).

      Good luck.

          Check out Jini. It's being proposed as an Apache project nowadays and
          really shines when it comes to making distributed services work
          together. Each application can be exposed as a Jini service whereby
          other services only know the Java interface the service proxy
          implements. How you implement the service itself (python?) or the
          communication between the proxy and the service back-end (XML-RPC? RMI?
          FTP? E-mail?) is completely up to you. Jini may look difficult at the
          beginning, but distributed systems are inherently difficult. Jini just
          makes them clear and forces you to deal with them in the easiest way
          possible. In my opinion Jini is one of the best kept secrets of
          distributed computing. Read up on the vision behind Jini to get an idea
          of mother of all SOA technologies.

              CORBA's wire protocol (GIOP/IIOP) is heavily used in (java) EJB servers.

              Can someone suggest me a better option or is corba fine?
              Well, if you are in a 100% python environment, I would suggest
              to use Pyro instead (http://pyro.sf.net)
              Or some other pure-Python RPC mechanism.

                  If, on the other hand, you want/have to combine different programming
                  languages and different environments, then CORBA will be a big help. For
                  example: Making objects implemented in Python on a Linux machine work with
                  objects implemented in C++ on a Windows machine (or even with objects
                  implemented in COBOL on a mainframe) will be no problem at all.

                  In our company we use CORBA a lot, even though we mostly use Python these
                  days. It gives us a lot of flexibility, while on the other hand it 'forces'
                  us to strictly define the interfaces of our objects before implementing
                  them. But that is a good thing :)
