Just to clarify...
The first page displays your form and lets the user fill it in and submit it to the page addcusresulte.jsp
Is the code under "nextpage" in your post what is in addcusresulte.jsp?

this code invoking a method that suppose to insert new data into the DB
i comment it because i dont want to receive NULL EXCEPTION
the output for the code now will beJava Code:<%-- MBank bank = MBank.instance(); bank.addClient(user.getPassword(), user.getFirstName(), user.getLastName(), user.getAddrese(), user.getEmail(), user.getPhoneNum(), user.getComments()); --%>
Java Code:user name is .. NULL customer has been added to the DB

You have to read the response object to get the form data. That should be done, in your case, in addcusresulte.jsp (directly or indirectly). Getting nulls maybe a sign that your not reading the response object or you are not putting the values from the response object in Mbank.
As I don't see code that reads the response object I can only speculate on want your problem is. That's why I asked the question I did in my first post.
