Passing a Collection object from 1 JSP to another without scoping it to session

[Andrew Latham <al...@kanbay.com>]

Hope someone has had success with this.

Basically using Struts the results of a query are returned to a JSP page
and accessible via the "request" object with something like:
<%java.util.Collection requestCollection = (java.util.Collection)
request.getAttribute("classificationlist"); %>

I'm trying to pass this to another JSP page. I've tried:
<%request.setAttribute("classificationlist", requestCollection); %>

Which doesn't error but its value is NULL on the next JSP. All doco and
other discussion forums suggest this method, but what I'm finding is
this will only work if I use the <jsp:forward> or <jsp:include>. Is
there a way to pass this to a page which is access by a <a
href="nextpage.jsp">Next</a>? I currently do this by rescoping to
session but the problem with this is it hangs around until I log out.

Any suggestions/help appreciated.

I think that you will find the answer to this to be no. The scope of a
request object is the servlet service method, so if you are processing a
different request, you are automatically going to have a different
request object.
