Where Do I Create Session, Set Attribute, etc. In Struts?

[JiaPei Jen]

I use container-managed form-based authentication to verify users in Struts(it works well).
Now, I want to create a session and set user's name after users successfully log in:

HttpSession session = request.getSession( true );
if ( session.isNew() ) 
{
   student.setName(request.getParameter("username"));
   session.setAttribute("student", student);
}

First of all, in the context of container managed authentication, can I write:

 
   student.setName(request.getParameter("username"));

Second, what is the proper place to insert the aforementioned codes?
The container intercepts and takes care of the authentication when the LOGON button is clicked <html:link forward="logon">LOGON</html:link>
and

 
     <forward
        name="logon"
        redirect="true"
        path="/do/Menu"/>

and the action controller is in the scaffold folder:

    <action
        path="/Menu"
        name="menuForm"
        type="org.apache.struts.scaffold.ExistsAttributeAction"
        parameter="application;HOURS">
        <forward
            name="success"
            path=".article.Menu"/>
        <forward
            name="failure"
            path="/do/MenuCreate"/>
    </action>

where .article.Menu is a tile.
