RE: action mapping question

[Bartley, Chris P]

You shouldn't have to have a form bean.  Here's the global forward I use for
the logout action:

        <forward name="forward.logout" path="/exec/logout"/>

Here's my action mapping for my logout action (Struts 1.0.2, with Tiles):

        <action path="/logout"
type="com.sprintpcs.ptt.controller.authentication.LogoutAction">
            <forward name="forward.success" path="template.login"/>
        </action>

The action class is short n' sweet (my abstract ActionSupport class
overrides Action's perform() method and then calls the abstract execute()
method):

public class LogoutAction extends ActionSupport {
     public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
IOException, ServletException {
        HttpSession session = request.getSession();
        if (session != null) {
            session.removeAttribute(USER_OBJECT_SESSION_ATTRIBUTE_KEY);
            session.invalidate();
        }
        return mapping.findForward(SUCCESS);
    }
}

So, then, all you need to do to let the user logout is provide a simple link
like this:

   <html:link forward="forward.logout"><bean:message
key="key.logout"/></html:link>

That should do it!

Hope this helps,

chris
