Using the Network Server with preexisting Derby applications

You must modify Java applications that currently run against Derby in embedded mode so that they work with the Derby Network Server. The topics in this section discuss these changes.

• The Network Server and JVMs
  
• Installing required jar files and adding them to the classpath
  
• Starting the Network Server
  To start the Network Server, you can invoke a script, a jar file, or a class.
• Shutting down the Network Server
  To shut down a Network Server, you can invoke a script, a jar file, or a class.
• Obtaining system information
  
• Accessing the Network Server by using the network client driver
  When connecting to the Network Server, your application needs to load a driver and connection URL that is specific to the Network Server. In addition, you must specify a user name and password if you are using authentication.
• Accessing the Network Server by using a DataSource object
  The Network Server supports the Derby Network Client driver DataSource classes org.apache.derby.jdbc.ClientDataSource and org.apache.derby.jdbc.ClientConnectionPoolDataSource on all supported Java SE platforms.
• XA and the Network Server
  
• Using the Derby tools with the Network Server
  
• Differences between running Derby in embedded mode and using the Network Server
