Hello Guys, I am about to start on this module below. I have asked this I think a month ago and only after finishing the rest of my small website will I implement this. Anyway im on track on learning the token creation for struts and the quartzs plugin. I was wondering if I will be sending the file streaming or I can just have a forward in my action mapping that would serialized the file?
Thanks in advance Richard On Wed, 13 Oct 2004 10:12:38 -0700, Wiebe de Jong <[EMAIL PROTECTED]> wrote: > The only way to make a link go away is to make it dynamic.
