[omniORB] Finding methods in objects / part 2

[Casillas_Juan_M/madrid_tecnologia@sinvest.es]

Hi again

   Well the Interface Repository sounds great (thanks Duncan), but
omniorb doesn't have
   is own one; and Stefan's answer sounds well also; I think about the
following:
   =20
   well, our sample scenario is one program (say A) asking for =20
   all the interfaces that have a method called hello(). All the
interfaces
   running must answer its IOR and type (to allow A comunicate with
   them) to A.
   =20
   Well, Im thinking about this:

   - first of all, all the programs are attached to an Event Channel
   - all the programs runs and adaptor to get and put events (the event
   is a piece of information, more or less like a e-mail message).
   - A put an event to the Event Channel asking for the method
   - All the running programs get the Event (The EventChannel runs
   like a broadcast net) process it (maybe using a DII to check =20
   if their interface has this method) and return via Event Channel
   the answer.

   Ok, but ...

      How A can instantiate new objects from the implementations,
      A knows the IOR, but ... program A can't cast dinamically new
      objects from a string ... or It can ?

      I want to avoid SPOFs (Single Point Of Failure) so the answer
      need to be as distributed and fault tolerant as posible ...

Kind regards
