Opening a NEW browser for a 2nd content type from an action
Hey all
is it possible to forme my struts app to open up a second browser window for
the purpose of streaming a different content type (like a pdf file) into it
while maintaining the page in the original browser?
Essentially, I have a nicely rendered HTML report in browser "a" and when
the user clicks "export to PDF" or "export to excel" I want a NEW browser to
pop up into which I will send the response with the headerType set to the
appropriate type.
the generation of the XL and PDF is handled for me, but the app flow is
where Im foggy.
anyone done this?

As a general rule you always want to close any stream when done, unless
you know by design that you need it to remain open, so yes, you probably
want to close it.
That being said, I've seen *PLENTY* of code that does things like this
that don't close the stream, and as far as I could tell it was
well-behaved code otherwise... I suspect the container will close the
stream at the end of the request processing cycle if it's still open,
but I always close it to be certain. Better to be explicit :)

Wow, excellent. Thanks! is tehre anything IU need to do to close my
PrintWriter in the Action class? right now I have
response.setContentType("application/pdf");
response.setHeader("Content-disposition", "inline" );
PrintWriter out = response.getWriter();
socket.write(out); // I get my PDF through thtis socket
do I need to close() it explicitly?

Return null. That's it (seriously!) Null effectively means "do not
forward to anything, the response is completely formed".

Re: Opening a NEW browser for a 2nd content type from an action
Posted by David Johnson <ch...@gmail.com>.
Okay, I've got it opening the second browser (finally got back to it) using
the target="_new" in the form declaration, but here's the real problem
I'm in the action class, and I can can work on the response using
response.setContentType("application/pdf");
response.setHeader("Content-disposition", "inline" );
BUT, when I get to the end of my action class, what do I return? I cant
return to a JSP page because I've set the content type to be PDF (or excel)
So, instead of
mapping.findForward("success");
what can I do?

Ugh, I always forget the simple target attribute! Absolutely agreed,
that's probably the best approach.

whoa that's simple. I'm trying that first!!!! Thanks
One things though, I'll have to set the "target" conditionally, only when
the user clicks "PDF" or "EXCEL" since I dont **always** want it opening a
new window...

Re: Opening a NEW browser for a 2nd content type from an action
Posted by Aladin Alaily <st...@aladin.ca>.
Hi Dave,
This is pretty straightforward. In browser "a", you have a button that says:
"Export to PDF"
The code would look like this:
<html:form action="/exportToPdf.do" target="_NEW">
<submit name="export" value="Export to PDF">
</html>
When the user clicks on the button, the action "exportToPdf.do" opens an
ServletOutputStream and writes whatever you want. The headers are also
set to the content-type you want and the format you want (inline or
attachment).
