Thanks for your assistant and may God bless you all Amen.
Login.html page is what user use to login which, will take him to validateform.jsp page, inorder to check if the user is a register user to have access to the page. Then, the UsePage.jsp is a welcome page that's, if successfully. But the error that i encounter after using Deploytool is

Problem is here..
DbUserName=rs.getString(username);
DbPassword = rs.getString(password);
replace it with
DbUserName=rs.getString(1);
DbPassword = rs.getString(2);
Or
DbUserName=rs.getString("DbUserName");
DbPassword = rs.getString("DbPassword");
----------------------------------------
The code should be actually
String username = request.getParameter("username");
String password = request.getParameter("password");
while(rs.next()) {
DbUserName=rs.getString(1);
DbPassword = rs.getString(2);
if (username.equals(DbUserName) && password.equals(DbPassword)) {
}
else {
}
}
