Marcel,
Thanks for your great summary! BTW, I just wanted to let you know, we've switched to
omniORB2/Sun IDL (JDK1.2) instead of Visibroker. I felt that visi was just way too
expensive, and being a believer in the benefits of Open Source software (and reading
all the great posts re omniORB), I decided to give it a try. The Sun java libs are
just enough for the client, definitely not good enough for a server, IMO, but we're
running a C++ appserver and so this fits beautifully. The two work together quite
well, and I only have good things to say about omniORB, so if you have similar
requirements, you may want to look into it. I guess this is sounding a bit like a
pitch ;)
Naturally, all work splendidly on linux (with the exception of the absence of
idltojava compiler, which the Blackdown team should have up Real Soon Now, right?).
Cheers,
-A.
