[all below is my personal opinion]
I guess, all that DCOM vs. CORBA vs. RMI dispute is just yet another
religious war.
Please refrain from continuing this already off-topic thread as a flame
war, but from my experience (I'm almost the only UNIX freak in a company
which announces itself as a Microsoft Solution Provider) I can state a
few facts:
- CORBA is difficult, but understandable. Also, it's not free (the only
known to me free CORBA implementation is Voyager from
www.objectspace.com (they also have excellent, though a bit
heavy-weighted container library, JGL).
- RMI, as strange as it sounds, is a lot like CORBA, but it feels much
better in Java environment. The disadvantage (once again, for me) is
that I've been developing everything (including commercial applications)
under Linux, which meant much less support for everything commercial
and/or proprietary (JDK, Netscape with JDK 1.1 support (btw, released at
December 24)) - you depend on raw implementations - Java is not as
mature as I want it to be, but mature enough to see it as a great
opportunity to write a reusable code, thus speeding up the development.
- COM/DCOM/ActiveX is a technology strictly bound to Windows (and don't
pay attention to Microsoft announces to make it cross-platform - I don't
want to elaborate on this, the facts speak for themselves), which is not
an option to me - see, I've been to MS-DOS, then Windows 3.1, then OS/2,
then UNIX with Windows 95, now I'm on UNIX and pretty happy with that.
The bottomline - try to be protocol-independent. I've just implemented
the reusable client/server model which allows you to implement just a
business logic and select whatever protocol[s] is/are suitable for a
specific application and will try to stay with it.
