Question

I have an assignment to use JavaBeans to create an online Banking application. I am trying to make the signup form but I am having some issues. When the form submits I am not able to get the values.

The Form:

<jsp:include page="header.html"></jsp:include>

<h3>Create An Account</h3>
    <form action="process_new_user_account.jsp" method="post"  onsubmit="return validate_form(this)" >
    <fieldset>
        <legend>Personal Info</legend>

    <table width="650px" border="0" align="center">
      <tr>
        <td width="25%"><div align="right">First Name: </div></td>
        <td width="75%">
            <input type="text" onblur="return validate_field(this)" onchange="return validate_field(this)"  onfocus="return validate_field(this)" name="fname" tabindex="1" size="50"/>
        </td>
      </tr>
      <tr>

    </form>

       <jsp:include page="footer.html"></jsp:include>

The JSP page that the for submits to (its is short just for testing until I get it to work):

<%@page import="WebBank.Customer"%>
<jsp:useBean id="customer" scope="session" class="WebBank.Customer"/>
<jsp:setProperty name="customer" property="zip"/>


<jsp:include page="header.html"></jsp:include>

<h3>Welcome!</h3>
<p>Thank you for creating a new account with JAC Bank!</p>


<%
 System.out.println("Testing.....");
 System.out.println("Name: " + customer.getZip());
 %>

<jsp:include page="footer.html"></jsp:include>

There is also a class called Customer that has a default constructor and a String getZip() and void setZip( String zip ) methods.

Answer 1

I don t see a servlet to unpack the values from the input form, bind them to a Customer object, and add it to session. Where does that happen in your code?

It s called Model-2 MVC. Add a servlet and funnel requests to it. You ll fare better.

I d also recommend that you learn JSTL and remove all scriptlet code from your JSPs.
