HttpSession Java EE - java-ee-7

Question

Everyone!
So I have a little problem with httpsession and I don't know how to fixed it. here is the problem.
I have a Class Person which has aset<Product> and I set that class person into
the request.getSession like this.
String email = getRequest().getParameter("email");
String credential = getRequest().getParameter("credential");
validEmail(email);
validCredential(credential);
if(existError()){
setValues(email, credential);;
forward(login);
return;
}
PersonService ps = serviceFactory.getService(PersonService.class);
boolean success = ps.validatePasswordAndEmail(email, credential);
if(success){
Person person = ps.getPersonByEmail(email);
getSession().setAttribute("person", person); here you can see the object person into the session
forward("/packed.jsp");
}else{
addError("Email or Credential is not valid!");
setValues(email, credential);
forward(login);
return;
}
After that if the users put their correct information they will come to another
file called packed.jsp and they are logged.
My problem is when I edit a product's person who are logged into the system. let me show my code here
The page called packed.jsp has a buttom where the person who are logged click
and then he comes to this servlet below
public class EditProductAction extends Action {
private String editProduct = "/edit_product.jsp";
private String packed = "/packed.jsp";
#Override
public void process() throws Exception {
Integer id = Integer.parseInt(getRequest().getParameter("id"));
String brand = getRequest().getParameter("brand");
String model = getRequest().getParameter("model");
String name = getRequest().getParameter("name");
String quantity = getRequest().getParameter("quantity");
String color = getRequest().getParameter("color");
String info = getRequest().getParameter("info");
ProductService ps = serviceFactory.getService(ProductService.class);
Product product = ps.getProductByID(id);
if(name == null){
getRequest().setAttribute("product",product);
forward(editProduct);
return;
}
product.setBrand(brand);
product.setModel(model);
product.setName(name);
product.setQuantity(Integer.parseInt(quantity));
product.setColor(color);
product.setInfo(info);
ps.update(product);
getResponse().sendRedirect(getRequest().getContextPath()+packed);
}
}
As you can see everything works fine but when I come back to the page packed.jsp
it doesn't show the product modyfied but in the database works fine, I mean the product has been modyfied. here packed.jsp
<div class="mainDiv">
<table border="1px" width="80%">
<tr>
<th>BRAND</th>
<th>MODEL</th>
<th>NAME</th>
<th>QUANTITY</th>
<th>COLOR</th>
<th>INFO</th>
<th>EDIT</th>
<th>DELETE</th>
</tr>
<c:choose>
<c:when test="${empty person.products}">
<tr>
<td colspan="8" align="center"><span>You don't have any product yet!</span></td>
</tr>
</c:when>
<c:otherwise>
<c:forEach var="p" items="${person.products}">
<c:url var="urlDel" value="servlet">
<c:param name="id" value="${p.id}" />
</c:url>
<c:url var="urlEdit" value="EditProduct.action">
<c:param name="id" value="${p.id}" />
</c:url>
<tr>
<td>${p.brand}</td>
<td>${p.model}</td>
<td>${p.name}</td>
<td>${p.quantity}</td>
<td>${p.color}</td>
<td>${p.info}</td>
<td><img src="<%=request.getContextPath()%>/images/edit.png"></td>
<td><img src="<%=request.getContextPath()%>/images/delete.png"></td>
</tr>
</c:forEach>
</c:otherwise>
</c:choose>
</table>
I would like to change the product and then when I back to packed.jsp I want to see the product modyfied. Thank you very much everyone.

Answer 1

I found a solution by creating another class with those objects and then put it the session. It works.
