Great attempt Faizal. Excellent tutorial for the begineers.

ps.setString(1, "First Name");
ps.setString(2, "Last Name");
ps.setId(3, 1);
ps.executeUpdate();

The third statement in the above code snippet must be ps.setInt(3,1) and not ps.setId(3,1)

it is however mentioned correctly in the complete servlet code. thought you should know.
