In samples we use the Java DB, i.e. the SQL database implementation that comes with the Java SE Development Kit (JDK) by Oracle (except for Mac OS). Java DB is essentially the same as the Apache Derby DB, that can be found here: http://db.apache.org/derby/

The instructions below apply to Java DB. Derby can be used similarly.

To run the Java DB in server mode, which is what we want to do, run
10
11
<pre><code class="ruby">
12
mkdir derby
13
cd derby
14
java -jar $JAVA_HOME/db/lib/derbyrun.jar server start
15
</code></pre>

assuming you want to run it in the folder *derby*. At a second time you can omit the "mkdir" command of course. The environment variable JAVA_HOME is expected to point to your JDK installation folder.

On Windows run

<pre><code class="ruby">
22
mkdir derby
23
cd derby
24
java -jar %JAVA_HOME%\db\lib\derbyrun.jar server start

</code></pre>

In order to interactively query Java DB, we recommand to use the Data Source Explorer view in Eclipse. But any SQL client that can make use of JDBC drivers should be fine. The driver for Java DB can be found (at the time of this writing) in *$JAVA_HOME/db/lib/derbyclient.jar* (and similarly on Windows).
