Anthony,
Here's another option. If, in your Action, it's determined that the popup
is needed, set a request attribute. Then in your JSP, check for the
existence of the request attribute, using <logic:present> for example, and
create a custom tag to generate the required Javascript. The custom tag
could even get needed data from the request. For example,
<logic:present name="popup">
<mytag:popup />
</logic:present>
The popupTag class would then generate and write the appropriate Javascript.
HTH,
Karen

Anthony,
the Action itself has no idea of the front end (the HTML/Javascript pages).
It would work just as well if the presentation layer was a Java Swing GUI or
whatever. So I'd say that no, you can't open a JS window from your Action.
What you can do is playing with the Action execution and the returned pages
with the <body onload=""> Javascript:
- call the Action to perform any processing or validation
- if you don't need the popup, that's standard stuff
- if you need to open a popup after the execution, generate a page that uses
<body onload="openPopup(URL);"> or similar
I realize this is not optimal (it's a "hacky" approach) but I'm pretty sure
it can be modeled properly. And there may be better ways to handle it (that
I'm unaware of :) )
HTH
