# Running the SimpleNetworkClientSample program

To connect to the Network Server that has been started with the `SimpleNetworkServerSample` program, follow these steps.

1. Open a command prompt and change directories to the `%DERBY_HOME%\demo\nserverdemo` directory, where `%DERBY_HOME%` is the directory where you installed Derby.
2. Set the classpath to include the following jar files:
   - The current directory (".")
   - `derbyclient.jar`
   - `derbyshared.jar`
   - `derbytools.jar`
3. After you set up your environment correctly, run the `SimpleNetworkClientSample` program from the same directory:

       java SimpleNetworkClientSample

   If the program runs successfully, you will receive output similar to that shown in the following example:

       Starting Sample client program
       Got a client connection via the DriverManager.
       connection from datasource; getDriverName = Apache Derby Network Client JDBC Driver
       Got a client connection via a DataSource.
       Testing the connection obtained via DriverManager by executing a sample query
       number of rows in sys.systables = 23
       Testing the connection obtained via a DataSource by executing a sample query
       number of rows in sys.systables = 23
       Goodbye!

4. After running the program, return to the command prompt where you ran the `SimpleNetworkServerSample` program and press Enter.
