This should probably be an answer on the Wiki since I see this asked quite a
bit...
No, you cannot open a new window from an Action. Not directly anyway. Opening
a window is strictly a client-side activity. Therefore, you have two choices:
(1) Submit a form to _blank, as you said (actually, I think it's _new, but my
memory sucks so I'm not sure)
(2) Use Javascript to open it, as you have already
I have something similar on all my pages... I can return a message from any
Action that is displayed via JS alert(). To do this, I simply send a "message"
attribute back in request, and every page checks if it's null onLoad, and if
not calls:
alert("<%=(String)request.getAttribute("message")%>");
Since all my JSP's import a common file for things like this, it's only in one
place.
I'm not sure if you want the new window to open in response to a for submission
(in which case just targeting a new window is probably the better idea) or
variably depending on what the server returns. I think it's the later based on
what you said, so I think something like I do would suit you.
