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
