Problem with retrieving Data

Question

I am reading the JBDC basic tutorial on Sun website.
Yesterday, i had problems with connecting the driver and to the database.
Now many folks on Sun forums help me to figure it out already.
Now i wanna retrieve the data from the database i have created. But i got error.
Exception in thread "main" java.sql.SQLSyntaxErrorException: Table/View 'COFFEES' does not exist.

If so, how could we do that ?
Please help me !!!

Here is my code. It's just something following what the tutorial on sun said:
import java.sql.*;
import org.apache.derby.client.am.SqlException;
public class HelloWorld {
     private static Connection con;
      * @param args
      * @throws SQLException
     public static void main(String[] args) throws SQLException, SqlException{
          // TODO Auto-generated method stub
          String url = "jdbc:derby:COFFEEBREAK";
     try{
          Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
          System.out.println("Driver connected...");
     }catch(java.lang.ClassNotFoundException e){
          System.err.print("ClassNotFoundException : ");
          System.err.println(e.getMessage());
     try{
          con = DriverManager.getConnection(url);
          System.out.println("Database connected..");
     }catch(Exception e){
          System.err.print("Connection Error:");
          System.out.println(e.getMessage());
     // Retrieve the data from the database
     Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);
     ResultSet srs = stmt.executeQuery("SELECT * FROM COFFEEBREAK.COFFEES");
     while (srs.next()){
          String name = srs.getString("COF_NAME");
          float price = srs.getFloat("PRICE");
          System.out.println(name+ "               "+ price);
