set bean property with request attribut

[Marko Debac]

Hi ranchers,

I got this little problem:
I have

 <% request.setAttribute("list", list);%>

and I want to replace curent property of session scoped attribute "user" - users list.

my bean "user" is:

  public class User {    
    private String username;    
    private UserList[] List;  
//.. getters and setters

How can I do that within JSTL?
I supose with useBean and setProperty, but I am confused with getting list from request scope and puting her on the right place in user bean from session scope.

Because I cant do this:

  <jsp:useBean id="user" class="User" scope="session"  />
        <jsp:setProperty name="user" property="List" value="<% request.getAttribute("list")%>"

please help,
regardes,
Marko

I'm not sure if this is exactly what you are after, and you haven't provided enough info for a definitive answer, but something in the form of:

<c:set target="${someBean}" property="propertyName" value="${anotherBean.someValue}"/>
    

may be what you are asking.

I think not, because I have two beans, but one bean HAS A list[] of second beans for his property. And I have instance of that first bean filled up from database (and all his property), and set in session scope.

Now, I get new list[] from somewhere (web services operation called from jsp)

<%
    try {
         request.setAttribute("list", getAgregatorSEIPort().operationNewList(//some parameters));
    } catch(java.rmi.RemoteException ex) {
        // TODO handle remote exception
    } catch(Exception ex) {
        // TODO handle custom exceptions here
    }
    %>    

and I set it like request attribute by name "list".
Further, I need to put (replace existing) list in session scope attribute (upper described instance - session.setAttribute("user", user)), with no scriptlet

cheers,
Marko

Surely this does it?

<c:set target="sessionScope.user" property="list" value="${requestScope.list}"/>

its approximately equivalent to user.setList(request.getAttribute("list"));
