In my opinion, Eric, this is a bad solution. There are lots of reasons this
is bad. Rather than go through them, I would suggest you just add the logic
in /search.do?query=42 at the point you get the failure form
/retrieve.do?id=42.
I agree with Jack here. The code to get back your Collection of objects
based on "id 42" should be about one line. Then maybe another to
populate the request so you aren't really saving maybe lines of code
forwarding to another action. So for example if whatever action is
processing your /retrieve.do?id=42 simply do something like...
retrieveAction(..) -->
String forwardName = "success";
Item item = service.getItemFromDB( 42 );
if ( item == null ) {
Collection items = service.performSearch( 42 );
request.setAttribute("items", items );
forwardName = "itemNotFound";
}else {
//probably put item in scope
request.setAttribute("item", item );
}
return (mapping.findForward(forwardName ));
