Explanation / Answer

<%
String loginbuttonClicked = request.getParameter("submit");
//This is done to check whether the "Login" button is clicked
if(loginbuttonClicked != null)
{
//now we will be retrieving the username & password typed in by the user from the submitted form
String username = request.getParameter("username");
String password = request.getParameter("password");

String user;
String pass;
//
String query = "SELECT * from login";
dbselect.rs = dbselect.executeQuery(query);
while ((dbselect.rs).next())
{
user = (dbselect.rs).getString("login");
pass = (dbselect.rs).getString("password");
//this is done to verify whether the username & password entered by the user match any of the
entries in the login table of the movies database
if((user.equals(username)) && (pass.equals(password)))
{
//finally we will be redirecting to the page that can do shopping
response.sendRedirect("AddCART.jsp");
}
