Subject: Problems with drivers for Java DB (Derby)

I downloaded JavaDB from SUN for LINUX and tried it with XCode and Java
1.5 for Mac OS X 10.4.7 on a PowerBook G4 but got the following (Below)
that I am unable to cope with on the Mac. There seem to be a IBM driver
that is lacking and no way to get that to work for the Mac.
Java DB is "Sun's supported distribution of the Apache Derby 100% Java
technology open source database". In core areas, I don't believe that it
differs from Derby at all. IBM does something similar with Cloudscape and
Derby.
You're right, there's no Java DB for the Mac. OTOH, as another poster points
out, there's a version of Derby for the Mac, which I use extensively, and
which seems to work fine.
It was things like this that I was hoping Apple Computers to address in
Java 1.6 now that Java DB is claimed by SUN to be a integral part of Java
2 SE version 6.
Java SE 6 isn't shipping yet. Once Sun ships the official version, and
Apple does likewise, I'm sure that they will offer appropriate support. As
I say, Derby works fine now, so it's not a big jump.
By the way I have seen a analogous problem with mySQL too.
I haven't. I previously used MySQL Connector/J 3.1.12, with no problem.
We're in process of switching to 5.0.3, but again it seems to behave OK.
It seems like
it is easier to connect a camera to a mac than to get a relational
database to work from Java.
The difference is probably that Apple is
doing a job with USB-drivers. Apple do not seem to do the same job with
JDBC drivers. I hope that will change or that database implementers at
least make drivers available, for the Mac. If the jdbc drivers are not
easily available the point of the rest of the database seem to be of
academic value only.
There are lots of drivers that work on the Mac. Note that Type 4 drivers
are all Java, so most of them Just Work on the Mac with minimal work.
Since the other vendors for Java DB (IBM, SUN, Apache) do not address
Mac OS X in particular there seem to be at least implicit hints that the
jdbc-drivers for Java DB is Apples responsibility.
See above. Only Sun produces Java DB. Apache and IBM use different names
for the same project.
