I think there's a difference between 'supposed to work' and 'actually
works'. The Java stated aim is that any old java ought to work in any new
JRE. That's why Sun has deprecated loads of stuff but hasn't actually
(AFAIK) excised anything from the toolset. However, that does not preclude
some things not working, due to bugs in the JDK. As the Java API suite
grows (and how it grows) the possible testing paths will become ever more
convoluted. Hence the possibility of certain bits of the older APIs not
working in particular circumstances must inevitably increase. I would
expect those to be fixed by patch releases to 1.4 as they come to light.
But what do I know? We're still on good ol' 1.3 here. But I certainly
didn't notice any problems moving anything that had been developed in JDK
1.2 to JDK 1.3.

That must be the theory as put out by marketing. I have had quite a few
things not work after moving to JDK 1.4.x. In the end I gave up and went
back to what comes with Windows.

I think you're right to be concerned. One of the virtues (or problems - see
http://www.onjava.com/pub/a/onjava/2002/07/31/java3.html) of Java is that it
practices upwards compatibility: Java written for an earlier version of the
JDK ought to run in a later version. If JDeveloper9i genuinely won't run on
JDK 1.4 that is a real problem.

I know I may be a Java neophyte, but that kind of version hypersensitivity
*just* to run the tutorial does *not* give me great confidence. It
obviously doesn't work with JDK 1.4.whatever; will it fall over dead with
the next Windows Service Pack? With the next build of JDev have a
completely different footprint requirement? What happens when you have a
year's worth of code and other things the client is doing requires a newer
JDK?

Hello gurus! Finally I completed the JSP tutorial!
I tried Peter's suggestion and it didn't work the first time, after that I
downloaded JDK 1.3.1_04 and tried it, It allowed me to create the JSP, but
then JDev raised an error trying to test the BC4J. After several tests of
installing and deinstalling each JDK version (1.4.0_01 & 1.3.1_04) I got the
JSP error already mentioned for version 1.4.0 and the BC4J error for version
1.3.1.
Last night I tried Peter's suggestion again, dropped JDev and unzipped and
it worked fine with the JDK 1.3.1. so I'll keep this configuration.
Win2K + SP 2
JDev 9.0.2.829
JDK 1.3.1_04
Thanks Peter, Chris and everybody!
Victor Jaen.

Victor,
I have run that tutorial successfully. What I would do is unzip
JDeveloper into a new directory, move all your mywork\* directories
under the new_jdev\jdev directory and start again. You have to
reestablish your connections or export them from the old install and
import them again. Also, if you customized the IDE at all, you need to
reestablish those customizations.
I've experienced some unrelated problems lately with JSPs in 9.0.2
production (under NT, not Win2K) that reinstalling fixed.
Thanks to everyone for making ODTUG 2002 a great success! Plan now
for next year's conference: Loews Miami Beach, Florida, June 22-27, 2003.
