How to generically forward to page you came from?

2001-08-30 Thread Alex Colic 

Hi,

I am creating a generic action class that after it is finished it needs to
forward to the page that called it. I have tried mapping.getInput() but
obviously since I haven't specified a input page in the struts.xml for the
action class I can't use that. Any thoughts?

OBS.: I DON'T THINK THIS IS THE BEST WAY BUT...

You can use the method:
org.apache.struts.action.ActionMapping.addForward(ActionForward forward)
that use as parameter an ActionForward constructed with:
ActionForward(java.lang.String path)
where path is of course your base name
Any coments are welcome.

Alex,

Here is one approach. When linking to the generic action class, include the
URI of the page that the link is on as a parameter. For example:

% String referrer = request.getRequestURI();
   request.setAttribute(referrer, referrer); %

html:link href=/generic/action/class paramId=referrer
 paramName=referrerClick here/html:link

Within the action, parse the parameter that designates the referrer, and
construct an ActionForward back to it: For example:

return new ActionForward(request.getParameter(referrer));

Error checking code ommitted for the sake of brevity.

David
