Why my MySQL JDBC Connect fail??

Question

Dear friends:
I have following code:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class JdbcExample2 {
  public static void main(String args[]) {
    Connection con = null;
    try {
      Class.forName("com.mysql.jdbc.Driver").newInstance();
      //jdbc:mysql://host_name:port/dbname
//     con = DriverManager.getConnection("jdbc:MySQL:///test","admin", "admin");
      con = DriverManager.getConnection("jdbc:MySQL://localhost:3306/test","admin", "admin");
      if(!con.isClosed())
        System.out.println("Successfully connected to " +
          "MySQL server using TCP/IP...");
    } catch(Exception e) {
      System.err.println("Exception: " + e.getMessage());
    } finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
}But when I run , I got following error:
Exception: com.mysql.jdbc.Driver
My question is:
[1]. when I connect to MySQL Server through mySQL Client, I got
Enter password: *****
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 18 to server version: 4.1.21-community-nt
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
how Can I determine MySQL Server name?? I forgot when I install, maybe MySQL is my SQL Server name
[2]. Do I need to creat a user DSN name or System DSN name for MySQL Server?? which one is best??
How to do it??
[3]. How to make above simple JDBC program runnable??
Thanks

here Jdbc11.java:23 is:
Connection con = DriverManager.getConnection(
url,"admin", "YES");
my userID/Password = admin/admin;
