Running a Java DB Network Server¶

In samples we use the Java DB, i.e. the SQL database implementation that comes with the Java SE Development Kit (JDK).

For general information see here: http://docs.oracle.com/javadb/10.8.2.2/getstart/index.html

To run the Java DB in server mode, which is what we want to do, run

mkdir derby
cd derby
java -jar $JAVA_HOME/db/lib/derbyrun.jar server start

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

mkdir derby
cd derby
java -jar %JAVA_HOME%\db\lib\derbyrun.jar server start

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).
