Yup, NT only. There was talk of a JMidas, but I only ever saw a clientside bit.
>(Detect an anti-NT for application server bias here?)
Ooooh, I wounder why!? Maybe 'cos (from my POV) I have identical servers
(hardware) running an identical app (in java) under NT and Linux. The linux one
currently has an uptime of 7 days. The NT one needs rebooting every 3-5 days.
The Linux one is so short 'cos I had to shut it down last week.....
Oh, and something like Slowlarus is even more stable. :)
>What are the alternatives if you are determined that the middle tier is unix?
CORBA and DCOM pretty much. CORBA is 'native', DCOM is a fudge (tho a working
one). Both work with Java, CORBA also works with C++, Perl, etc etc.
I'd personally go with CORBA - Visi for Delphi is NICE (I'm doing that at the moment
vrs Linux/Java/Visi4Java3.4

Very true.

Write it in Java (the app server). Here's my take, as I've been doing the same
thing for 2 months now (2nd part of a 1.5 year project):
- Java middle tier on NT/Linux (take ya pick), targetting Interbase 5.6 on NT or
Linux, exposing corba objects.
- IIS (NT) or Apache (Linux) talking to JRun (JSP engine)
- JRun talks CORBA to the CORBA server (duh!)
- Delphi client talks to the CORBA server via VisiForDelphi.
easy :) I just program to an interface and a set of records rather than a database
connection.
Gimme a shout off the list (or on it :) ) if you want more info.
