Installing required jar files and adding them to the classpath/modulepath To use the Network Server and network client driver, add the following jar file to your server classpath/modulepath. derbyclient.jarderby.jar derbynet.jarderbyrun.jar
  • derbyrun.jar

Adding this file to your classpath/modulepath has the effect of including all of the classes. These classes are in the following jar files, which you can also add to your classpath/modulepath separately:

 derbyshared.jar

This jar file contains code which is common to all configurations.

 derbynet.jar

This jar file contains the Network Server code. It must be in your classpath/modulepath to start the Network Server.

 derby.jar

This jar file contains the database engine code. It must be in the classpath/modulepath in order for the Network Server to access databases. derby.jar is included in the Class-Path attribute of derbynet.jar's manifest file. If you have derbynet.jar in the classpath/modulepath and derby.jar is in the same directory as derbynet.jar, it is not necessary to include derby.jar explicitly.

 derbyclient.jar

This jar file contains the Network Client JDBC driver that is necessary for communication with the Network Server. It must be in the classpath/modulepath of the application on the client side in order to access databases over a network.

 derbytools.jar

This jar file contains the standard tools, such as ij, sysinfo, and dblook. This jar file also contains the DataSources.

 derbyoptionaltools.jar

This jar file contains additional tools, such as the Lucene plug-in. The derbyoptionaltools.jar file is not needed in your classpath/modulepath to run the Network Server, but it is automatically included by derbyrun.jar.

All of the jar files are in the $/lib directory.

provides script files for setting the classpath/modulepath to work with the Network Server. The scripts are located in the $/bin directory.
