Re: action mapping question

[Ted Husted]

The html:form tag expects there to be a ActionForm bean associated with 
the form. If you are using a button-only form, you still need to provide 
an ActionForm bean, even if it is an empty implementation. I generally 
keep one of these in my Struts toolkit to use throughout an application. 
Or, you could just use whatever bean is handy.

You don't need a bean with an Action, but you do need one to appease the 
html:form tag.

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:



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





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:

   

That should do it!

Hope this helps,

chris

RE: action mapping question

[Trieu, Danny]

Hmm This sound like it is the way 1.0 of struts was implemented.  I
haven't use 1.0 for quite sometime so I don't remember.  But, there is
something you can do.  You can set the attribute validate=false, so that the
controller don't have to call the validate method on your from bean.  You
Don't have to implement the validate method on your from bean, but if you do
return null or empty actionErrors.  As for input, I don't think you need to
provide one.

Sorry if I didn't help you in anyway:)

Danny

Ps. Move to 1.1

RE: action mapping question

[Trieu, Danny]

1) why would you need a logoff form?
2) what version of struts are you using?

You don't have to have a form bean declare for an action mapping.  The
reason it throw the exception 
Because you have the input attribute setting.  With this setting the
controller makes assumsion that your mapping has a from bean associate to it
and make call to the validate methods.  I guess the solution is not to
provide from bean mapping and input mapping for your action.

Hi,

Having a few problems getting my application working properly. Basically
I've got a logon.jsp page which posts to logon.do action, which then
validates and if successfull outputs search.jsp (shows in the browser as
/logon.do ).

then on search.jsp i have 2 forms, one to search.do and one to logoff.do

here's my action mapping for logoff:

  




first of all, i dont want to use a bean for the logoff action but it
complains otherwise, so for now i've used a form with a attribute dummy with
get/set/reset/validate  methodsis there a way not to have to do this? if
i dont have a form, I get an exception complaining the form bean is
null.

second, what should 'input' be? if i leave it as "/logon.do" then it works,
but also if i put it as "/tapssearch.jsp" it works..so what should it
be? and how can i set action-mapping to accept input from any page, seeing
as for example i'll want to be able to log-off from any one of the pages(bar
the logon one of course!) So that i dont have to write an action mapping for
every page that has a logoff form

cheers
