RE: action mapping question
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. danny -Original Message- From: Darren McGuinness [mailto:[EMAIL PROTECTED]] Sent: Friday, August 30, 2002 8:17 AM To: [EMAIL PROTECTED] Subject: action mapping question Hi, Having a few problems getting my application working properly.

RE: action mapping question
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.

RE: action mapping question
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.logoutbean:message
key=key.logout//html:link
That should do it!
Hope this helps,
chris

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:
action path=/logoff
type=struts1.action.LogoffAction
name=logoffForm
input=/logon.do
scope=request
forward name=success path=/logon.jsp/
forward name=failure path=/logon.jsp/
/action
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

Re: action mapping question
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. -Ted. then on search.jsp i have 2 forms, one to search.do and one to logoff.do here's my action mapping for logoff: action path=/logoff type=struts1.action.LogoffAction name=logoffForm input=/logon.do scope=request forward name=success path=/logon.jsp/ forward name=failure path=/logon.jsp/ /action 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!)
