Starting the Network Server from a Java application

Note that you should always properly shut down the Network Server after use, because failure to do so might result in unpredictable side-effects, such as blocked ports on the server.

There are two ways to start the Network Server from a Java application.

  • You can include the following line in the derby.properties file: 
    derby.drda.startNetworkServer=true
    This starts the server on the default port, 1527, listening on localhost (all interfaces).

    To specify a different port or a specific interface in the derby.properties file, include the following lines, respectively:

    derby.drda.portNumber=1110
derby.drda.host=myhost
    You can also specify the startNetworkServer and portNumber properties by using a Java command: 
    java -Dderby.drda.startNetworkServer=true
-Dderby.drda.portNumber=1110
-Dderby.drda.host=myhost yourApp
  • You can use the NetworkServerControl API to start the Network Server from a separate thread within a Java application: 
    NetworkServerControl server = new NetworkServerControl();
server.start (null);
