Runtime Error using JDBC Driver in NetBeans IDE 6.9.1

Question

Hello,
I receive a compiler error which reads as follows;
java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver
java.sql.SQLSyntaxErrorException: Schema 'DEMO' does not exist
Heres the main body of code i am trying to execute.
public class Main {
@param args the command line arguments
public static void main(String[] args) {
// TODO code application logic here
try{
Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
}catch(ClassNotFoundException e){
System.out.println(e);
try{
Connection con = DriverManager.getConnection("jdbc:derby://localhost:1527/SimpleDBDemo", "demo", "demo");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM DEMO.Table1");
while (rs.next()) {
String s = rs.getString("Name");
float n = rs.getFloat("Age");
System.out.println(s " " n);
}catch(SQLException e){
System.err.println(e);
I am using NetBeans IDE and have created a database under: Services->Databases-> Java DB->SimpleDBDemo.
I have a database connection in which theres a simple table (called "TABLE1") created which contains the names and ages of two people. I am trying to access the data of these two people.
From what i can figure out i am getting a runtime error. I have downloaded a folder called "Microsoft SQL Driver 2005 JDBC Driver" which contains the "sqljdbc.jar" executable file. I copied the jar file to the library in "Program files->Sun->javadb" and then added the file to the project libraries section i.e. "Project->properties->add JAR/Folder->sqljdbc.jar" in netbeans.
I am still getting the same runtime error. Have i the sqljdbc.jar file added in the wrong place?
Any help would be greatly appreciated.

Microsoft SQL Driver 2005 JDBC Driver is not the Derby driver.
You need the correct JDBC driver for the database you are using, you can't simply grab the first one you find.
