I never done stuff with popup windows, but I would consider trying
something like this:
* you open a new window and submit to action which validates input
(automatic validation is turned off);
* you manually call validate() from action class, and if input is
incorrect, you return a small html with javascript, which would close
current window (which is a popup), and would redirect to main window.
The downside: would not work without javascript. The location of main
window should be set either in struts-config.xml or maybe passed as
parameter or maybe found out via referer... Also, to show errors after
redirect you would have to stick them into session beforehand. Or to
append to redirected request.
* if data is ok, you respond with pdf to popup window directly or
forward/redirect
to action which responds with pdf.
As a side note, I personally don't like apps which open windows
themselves. I prefer to use "Open in a new window" option if I need it
in a new window.
