Hello,
The mappings that are set up in the struts-config.xml can be
modified programmatically. So, if you want to reconfigure a forward,
you would not need an if statement in the struts config, but I believe
you can do it in your program that references the forward.
For example:
ActionForward forward = mapping.findForward("success");
forward.setPath("my new path");
disclaimer:
I have not changed actual forwards this way (except by accident). I
have modified the paths in a forward, but I have always created a new
forward object to be returned by my ActionServlet. I would be worried
that a modified forward could be garbage collected and set back to its
original value from the struts-config when called for again. Maybe
someone else could comment on whether or not this is a potential problem.
I do it like this to avoid potential problems:
ActionForward forward = mapping.findForward("success");
ActionForward newForward = new ActionForward(forward.getPath());
//do stuff to modify path
return newForward;
Bill
forward.setPath("my new path");
