Problem with type 4 driver using oracle 10g

Question

HI,
I am unable to establish a type 4 connection with oracle 10g.
Specs:
Driver used: OracleDriver that comes with the ojdbc14.jar along with oracle 10g
JDK used: Tried using both j2sdk1.4.2 and using JDK 5.0
JRE: Again, JRE that was shipped with j2sdk 1.4.2 and JRE 5.0
OS: Windows XP sp2
I am able to compile the following piece of code, so there is no classpath problem, etc.
When I try to run the program, the exception thrown is "No Suitable Driver"
There is no problem with the TNSListener, etc...even if all Oracle related services in 'services.msc' are Started/Stopped, the error remains.
I am, however, able to establish the connection using type1 driver.
Please Help!

          //DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
          connection = DriverManager.getConnection("oracle:jdbc:thin:@127.0.0.1:1521", "scott", "tiger");
          //connection = DriverManager.getConnection("jdbc:odbc:dsn1", "scott", "tiger");
          System.out.println("Connection Established");
          statement = connection.createStatement();
          resultset = statement.executeQuery("select ename from emp");
          while(resultset.next())
               System.out.println(resultset.getString(1));
class Test
     public static void main(String args[]) throws SQLException, ClassNotFoundException
          TestConn obj = new TestConn();
          obj.testConn();
};

The JDBC URL should include the database SID. For example, if the database SID is Orcl
connection = DriverManager.getConnection("oracle:jdbc:thin:@127.0.0.1:1521:Orcl", "scott", "tiger");
