Java Connector via MySQL [ Cannot Connect ]

Question

I downloaded the MySql connector and extracted the connector and placed it at this directory,
C:\Program Files\Java\jdk1.5.0_06\jre\lib\ext
I also set the classpath as such by adding
ClassPath = .;C:\Program Files\Java\jdk1.5.0_06\jre\lib\ext\mysql-connector-java-3.1.12-bin.jar.Actually , I followed the tutorial at
http://www.stardeveloper.com/articles/display.html?article=2003090201&page=4.
I then executed this program below.
import java.sql.*;
public class Connect {
  public static void main(String args[]) {
    Connection con = null;
    try {
     Class.forName("com.mysql.jdbc.Driver").newInstance();
     con = DriverManager.getConnection("jdbc:mysql:///enron", "root", "horizon");
      if(!con.isClosed())
        System.out.println("Successfully connected to MySQL server...");
    } catch(Exception e) {
      System.err.println("Captured Exception: " + e.getMessage());
    } finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
However i was unable to connect..This is wat happened as below..
C:\>java Connect
Captured Exception: Communications link failure due to underlying exception:
** BEGIN NESTED EXCEPTION **

Hi thanks for the reply.
Although , I am though a bit baffled by your reply.
Where is it that you want me to add the URL.Not add the URL - change the one you have. Read the docs for the connector and follow that.
And where else should i place that jar file.I put it in my CLASSPATH, close to where the source for my project is. (That means not in one place, but several places. I duplicate the JAR file for every app that needs it.)
Cos I follow the tutorial at...
http://www.stardeveloper.com/articles/display.html?art

Unless You are saying that the above site is wrong..
If thats the case, can you point out another
alternative site which can guide me along .No time to read that site, nor do I have the interest.
The Sun Java tutorial is sufficient for using JDBC. As far as how you package and deploy apps, that's another matter. You should be using the class name and URL that your JDBC driver docs suggest.
