Re: Request parameters in action forward

[Lance Semmens]

You can use an org.apache.struts.action.ActionRedirect
ActionForward forward = mapping.findForward("reload");
ActionRedirect redirect = new ActionRedirect(forward);
redirect.addParameter("id", idValue);
return redirect;

Hi,
 I do have a SelectFooAction (actually it's called ChooseFooAction
:)). There is another problem though:
 This action is used in more than one places so I have to add a
parameter called action in it's url (action=display for a simple user,
action=edit for the admin etc). Since I have a lot of foo's, I have a
form in this page to select which category of Foo's to display. When
the user selects  a category, the page is reloaded (through another
"reload" mapping) which leads us from selectFoo.do?action=display to
selectFoo.do.
 Do you see a pattern here ;)?

exactly, send them back to wherever they go to select the foo they 
want to
look at.  Do you have a SelectFooAction?
