Storing object in session - struts2

Question

Hi I have something like this in struts.xml

   <action name="LoginAction" class="controller.LoginAction">
                <result name="error">/Error.jsp</result>
                <result name="success">/Wizard.jsp</result>
    </action>

Edited:

Upon successful execution of execute in the action the next page has data which it accesses using the request scope. How can i store the same data in session scope instead?

I read that HttpServletRequest object is passed as a parameter to the execute() method in a Struts action, and I can always retrieve the HttpSession object by using the request.getSession() and attaching data to it.

So if I am using something like this in controller.LoginAction

public String execute(HttpServletRequest req) {
    ...
}

Do I have to change struts.xml? execute does not get called when HttpServletRequest is added as a parameter.

   <action name="LoginAction" class="controller.LoginAction">
                <result name="error">/Error.jsp</result>
                <result name="success">/Wizard.jsp</result>
    </action>

Also is using session this way the best method ? I am trying to familiarize my self with the struts method.

other way to persist data than session or other way to store data in session. This is the perfect way to store data into session. — Felix Christy, Jun 12 '12 at 12:34
You read incorrectly or what you read was wrong; S2 action methods don't take any parameters. — Dave Newton, Jun 12 '12 at 13:18
That explains why the execute method wont be called with parameters. Thanks for clearing that up. — MistyD, Jun 12 '12 at 13:24
If I remember correctly, struts1 action methods took such parameters. I guess you got confused because of that — Anupam, Jun 12 '12 at 13:38

You can implement SessionAware interface:

public class LoginAction extends ActionSupport implements SessionAware {
    private Map session;

    public String execute() {
        session.put("key", "value");
        // Plus any additional action code
    }

    // Plus setter (and optionally getter) for session map.
}

Alternate way using ActionContext is explained here.

SessionAware is preferred over ActionContext. Here are some discussions on that:
