Thanks Frank. I was able to track down an issue with my SQL and have
resolved it.
I really appreciate this list...most of the time I lurk and glean
nuggets of goodness but on occasion when I've had some questions and
needed help...folks are there.
Cheers!

No, you don't need to implement StrutsFileDownload... What your
doing should work fine... Can you throw together a quick, simple
application that is nothing but a single Action that writes out
"ok" to the response and returns null? See if that works... if
what you describe is accurate, it sure sounds like something prior
to your Action is getting the output stream, which probably should
not be happening.

Hi Mike,
Yup. I did that and no error is thrown now, however I don't get
the download anymore....I'm thinking I need to implement
StrutsFileDownload instead and that's my link? Thoughts?

Hi.
Maybe it has worked before, but I think you actually make an
error : If you already send a stream back to the client, it's not
logic to return "mapping.findForward()" because nothing else can
be send to the browser at this point.
You should simply return "null" ...

Hi,
I asked this question of the POI user mailing list but it's
probably a question for this list. If you don't know what POI
is, check it out here:
http://jakarta.apache.org/poi/
I used to run Struts 1.2.9, POI 2.5 and could generate Excel
files from a servlet and download them without issue. I recently
upgraded to Struts 1.3.5 and POI 3 and it looks like I broke
that capability. I'm getting the following error:
java.lang.IllegalStateException: getOutputStream() has already
been called for this response
I've searched through the Net and the archives here for info but
nothing really seems to fit for my situation; it's mostly JSP.
I'm calling an Action servlet which makes a call to the model
and gets some data, creates a new workbook and then does this:
<snip>
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-disposition",
"attachment;filename=\"attendees.xls\"");
response.addHeader("Content-description", "Event
Attendees");
ServletOutputStream stream =
response.getOutputStream();
wb.write(stream);
stream.close();
...
forward = "SUCCESS";
...
return mapping.findForward(forward);
</snip>
It's what I did before I upgraded and things worked fine. Now
they don't
Any ideas? Am I missing something really obvious or was I
bending the rules a bit and taking chances with my data in my
previous config?
Cheers and thanks,
Jon
