After server restart I get - An I/O error occured while sending to the backend.

Hi,

I have simple JDBC client app running on Jetty.
Using 8.3 JDBC3 driver and PostgreSQL8.3 server running on localhost.

Any time I restart the PostgresQL server I get SQL error:
An I/O error occured while sending to the backend.

It appears that my application's connection to the server is not
re-established by some reason?

I am no expert in JDBC.
First I was using plan JDBC. I thought that using DB connection pool
will automagically reconnect and solve this problem.
Switching to Apache commons DBCP did not change anything.

What am I supposed to do to make it survive PostgreSQL server restart?

Here is my DB connection manager class:

public class DatabaseProvider {
    private static Connection connection;

    public void init() throws SQLException {

        connection = createConnection();
}

    private static Connection createConnection() throws SQLException{
        try {
            Class.forName(ConfigurationServlet.getConfigurationProperty("database.driver"));
        } catch (ClassNotFoundException e) {
            System.err.println("Database Driver class not found: " + e.getMessage());
            throw new SQLException("Driver class not found: "+e.getMessage());
        }


        DataSource dataSource =
setupDataSource(ConfigurationServlet.getConfigurationProperty("database.url"));
        Connection conn = dataSource.getConnection();
        //Connection conn = DriverManager.getConnection(url,dbprops );
        return conn;
    }

public static DataSource setupDataSource(String connectURI) {
              BasicDataSource ds = new BasicDataSource();
              ds.setDriverClassName(ConfigurationServlet.getConfigurationProperty("database.driver"));

             ds.setUrl(connectURI);
             return ds;
        }

    public void shutdown() {
        try {
            connection.close();
        } catch (SQLException e) {
            System.err.println("Error closing connection: "+e.getMessage());
        }
    }

    public static Connection getConnection() {
        return connection;
    }
}
