Use the derby.drda.startNetworkServer property to simplify embedding the Network Server in your Java application. When you set derby.drda.startNetworkServer to true, the Network Server will automatically start when you start Derby (in this context, Derby will start when the embedded driver is loaded). Only one Network Server can be started in a JVM.
NOTE: If you start the Network Server with this property set to true, the Network Server will stop when your application ends or when you stop it by other means (e.g. by using the Java API, the command line interface, or by shutting down the Derby system), whichever comes first.
derby.drda.startNetworkServer=[true | false]
Static. You must shut down the Network Server and restart Derby for this change to take effect.
