Help on Sessions

I have several forms that I am using to collect information as a part of a shopping cart (billing, shipping, payment, etc.). I want to be able to submit each form and temporarily store the information. Then I want to be able to display it several pages later as a confirmation page, to verify it is all correct.

From what I can tell there appears to be two ways of potentially handling this. My question is why would I use one of the following approaches over the other?

FIRST APPROACH

[page1.jsp]

<form method="post" action="page2.jsp" name="myForm">
<input type="text" name="firstname" size="30">
<input type="text" name="lastname" size="30">
<input type="submit" value="Submit">
</form>


[page2.jsp]

<% HttpSession user = request.getSession(true);
user.setAttribute("fname", request.getParameter("firstname"));
user.setAttribute("lname", request.getParameter("lastname"));
%>

[page3.jsp]

<% HttpSession user = request.getSession(true); %>
<%= user.getAttribute("fname") %>
<%= user.getAttribute("lname") %>

----------------------------------------------------------------

SECOND APPROACH

[MyBean.java]

package myPackage;

public class MyBean {
  private String fname;
  private String lname;
  public MyBean() {
    name = "";
  }

  public String getFname() {
    return fname;
  }

 
  public void setFname(String x) {
    fname = x;
  }

  public String getLname() {
    return lname;
  }

 
  public void setLname(String y) {
    lname = y;
  }
}



[page1.jsp]

<form method="post" action="page2.jsp" name="myForm">
<input type="text" name="firstname" size="30">
<input type="text" name="lastname" size="30">
<input type="submit" value="Submit">
</form>




[page2.jsp]

<jsp:useBean class="myPackage.MyBean " id="firstBean" scope="session" />
String firstname = request.getParameter("firstname");
String lastname = request.getParameter("lastname");
<jsp:setProperty name="firstBean" property="fname" value="firstname" />
<jsp:setProperty name="firstBean" property="lname" value="lastname" />



[page3.jsp]
<jsp:useBean class="myPackage.MyBean " id="firstBean" scope="session" />
<jsp:getProperty name="firstBean" property="fname" />
<jsp:getProperty name="firstBean" property="lname" />
