Daniel Le Berre commented on DERBY-7097:
----------------------------------------
Hi Richard,
Thanks a lot!
Regarding the tutorials, there is no hope to see them updated. Most of them
have been written a while ago. They haven't been updated since then.
I guess I will just update an answer on Stack Overflow explaining the issue
with the JPMS compliant derby.
Thanks again for the quick feedback and the resolution of the issue.
Keep up the good work.

> In earlier version of Derby, and as reported in the documentation, the
> EmbeddedDriver class was in derby.jar.
> As such, it was quite easy to deploy a webapp with an embedded derby
> database: it was sufficient to just add a derby.jar file to the project
> library.
> In current releases of derby (10.15.2.0), the EmbeddedDriver class is no
> longer in the derby.jar file but in the derbytools.jar file.

> As such, most of the tutorials found on the internet about "how to use derby
> in embedded mode" are just wrong because they simply mention derby.jar as a
> dependency.
> Worst, derby own documentation is not up to date: as such, I had no way to
> understand why new releases of this tool that I have been using for more than
> a decade in the classroom suddenly did not work anymore.
> The explanation is finally simple: I just wonder how such impacting decision
> could be done without proper documentation.
> I am also surprised to be the first one reporting this, since the problem
> exists since at least a year.
> There are two possible fix to this issue:
> * move back the EmbeddedDriver class to derby.jar (my favorite option I
> would say), but I guess there is a good reason for moving those classes to
> derbytools.jar
> * update the documentation on Derby's web site, with a quite visible alert
> about this change.
>
> I have been a pretty happy user of derby for years, and will certainly be in
> the future. Thanks for that great tool. However, that breaking change has
> been particularly annoying, which is the reason of that bug report.
