Error when run the compiled code

Question

I have code below,
import java.sql.*;
public class testmysql{
     public static void main(String args[]){
          Connection conn = null;
try{
String userName = "root";
String password = "password";
String url = "jdbc:mysql://localhost:3307/ectol_db";
Class.forName ("com.mysql.jdbc.Driver").newInstance ();
conn = DriverManager.getConnection (url, userName, password);
System.out.println ("Database connection established");
}catch (Exception e) {
          e.printStackTrace();
System.err.println ("Cannot connect to database server");
}finally{
if (conn != null){
try{
conn.close ();
System.out.println ("Database connection terminated");
}catch (Exception e) {
     e.printStackTrace();
     /* ignore close errors */
and i have the mysql-connector-5.0.6.jar
I able to compile code with javac testmysql.java command
However, when i try to run the code with java testmysql command, it prompt me error below
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

Actually, the jar and class file was in the same path...
Thus, what the correct command i need to run the my code?Then your classpath would be .;mysql.jar (or whatever the heck the name of the connector was).
So java -cp .;mysql.jar foo.bar.MyClass
