Well actually, it seems to work just fine. Just make sure that you use
the JVM 1.4.1 AND copy the 5.2.2 frameworks over to Jaguar.
I just range a regression test against the app and obtained identical
results running against 5.2.2 on Panther and on Jaguar.
It doesn't guarantee that you will...I am sure that the only supported
way is 5.2.2 on Panther.
But hey...it's Java.

The question is this.
Can I upgrade my development system to Panther, XCode, WO 5.2.2 while
deploying the built applications on Mac OS X 10.2.8?
A couple of respondents said they were doing this without finding any
problems.
One very knowledgeable poster said it would be asking for trouble.
I would strongly advise against developing your applications with
5.2.2. on Panther and then deploying them on 5.2.1 on Jagular. All
java frameworks in WebObjects 5.2.2, to name a few examples
JavaWebObjects.framework, JavaFoundation.framework,
JavaEOControl.framework, etc, are all compiled against Java Virtual
Machine ver. 1.4.1. Java frameworks in WebObjects 5.2.1 were compiled
with JVM 1.3.1. Do you think it'd work, if you compile your
applications with 1.4.1 and then run it on 1.3.1 ? The answer is NO.
You may ask "What if I change the default JVM to 1.4.1 on Mac OS X
Server 10.2.8 ? The answer is still NO. You may try it and you would
run into NoClassDefFoundError.
Here's the bit I didn't ask:
Would I have to install WO 5.2.2 deployment on the OS X 10.2.8
deployment machine? Maybe some respondents were assuming that I
meant this and others were not. Maybe it is not even possible to
install 5.2.2 on OS X 10.2.8.
The only legal way to get the WebObjects 5.2.2. Deployment is to
upgrade your OS to Panther Server.
