Subject Re: [OFF TOPIC] ServletOutputstream Issue
Date Mon, 14 Apr 2003 17:38:26 GMT
Yes, I have the header in place, and the utility creates a workbook, and then I use the WorkBook.write(
outputstream). But for some reason it's not recognizing the excel data, and it's trying to
open it up as the servlet name in excel and saying that the file cannot be opened. But when
I try to generate the file to disk it works fine.

an xls file or open one, and I'm getting an error of site unavailable and the download fails.
Any help would be great with this, since I'm obviously missing something about the outputstream.
Again, thanks for taking the time to review my question, Lior

How does your servlet serve the Excel file? I am assuming that you are 
using POI to write directly to the ServletOutputStream, obtained with 
response.getOutputStream()? If I am not mistaken you may need to set 
the content-type of the outgoing response:
