Filling-in a Bean inside a Servlet

    Hi, I'm working on a CRUD app. I have a customer bean, with Name, City,
Phone, etc..

    I also have a jsp page (CustomerEdit.jsp) with all the text fields,
that should be used to Add a new customer AND Edit an existent customer.

----------------------------------------
<FORM method="POST" ACTION="CustomerController">
<jsp:useBean id="customer" class="com.enplater.ofertes.Client"
scope="request">
  <jsp:setProperty name="customer" property="*" />
</jsp:useBean>

<table>
<tr>
  <td>NOM</td><td><INPUT name="name" TYPE="text" size="10"
value="${client.nom}"></td>
</tr>


----------------------------------------
When submited, the FORM calls a Servlet, the CustomerController
servlet. From this Servlet, I should create a Customer Bean, and then
get all request parameters and calling the correspondent setters of the
Bean:

Customer c=new Customer();
String name=request.getParameter("name");
String phone=request.getParameter("phone");
c.setName(name);
c.setPhone(phone);

The question is:

    Can I fill all the properties of the Bean magically on a line, The
same way that the jsp does it via <jsp:setProperty property="*"> ???
    There must be a trick or a workaround, because this method doesn't
scale. There must be some trick to achieve to get a Customer object as a
parameter:

    HttpSession sess=request.getSession();
    Customer c=(Customer) sess.getParamter("customer");

    Or is this all stuff as easy as using session-scoped attributes?
