--------------------------------------
Summary: Update documentation to allow users to properly use
EmbeddedDriver
Key: DERBY-7097
URL: https://issues.apache.org/jira/browse/DERBY-7097
Project: Derby
Issue Type: Bug
Components: Documentation
Affects Versions: 10.15.2.0
Reporter: Daniel Le Berre
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 using 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.
