Connecting a client to the Network Server with the SimpleNetworkClientSample program

The SimpleNetworkClientSample program is a client program that interacts with the Derby Network Server from another JVM. The program performs the following tasks:

• Loads the network client driver. (Note that this step is not necessary if you are running the client on JDK 1.6 or higher. In that environment, the network client driver loads automatically.)
• Obtains a client connection by using the DriverManager.
• Obtains a client connection by using a DataSource.
• Tests the database connections by running a sample query.
• Closes the connections and then exits the program.

To run the sample program, use the following files in the %JAVA_HOME%\demo\db\programs\nserverdemo\ directory:

• The source file: SimpleNetworkClientSample.java.
• The compiled class file: SimpleNetworkClientSample.class.
