I have written the following Servlet for Login Page without using MVC pattern:
Correct UserNames and Passwords are stored in MSAccess Database.



The problem is this ..when I enter wrong UserName and Password, it prints ‘Invalid UserName or Password’ many times.But I want it only once.How to overcome this problem.please help me to make correction in the code.

You're selecting every name in the table and then comparing them in your Java code.
Why not build a select statement that looks for the exact username and password entered by the user.

If you have an empty resultSet, then you know there was no match.
