> 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.
> ```
> $ for i in `ls *.jar`; do echo $i ; jar tf $i | grep Driver ; done

> 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.
