Don't write the PDF to the output stream when you do now. Instead, return an ActionMapping which causes the input page to be refreshed. In that input page, have a conditional block which recognizes that things are good to make the PDF, and inside that block, cause the browser to load the PDF. You could do that with <meta http-equiv="refresh"...> (but then i don't think you can make it happen in a new window) or you could do it with javascript. If you insist on generating the PDF when you do now, write it to the filesystem instead, and have the automated bit load the PDF directly; alternatively, defer generating the PDF to a separate action (which is probably a cleaner separation of concerns anyway) and have the automated bit call that action, causing the PDF to be generated. Does that make sense?
