Re: Struts Excel download using POI... throwing

Chris,
Thanks for your reply..
How can I avoid this..
I want to download the excel file in the same screen where the download
button was there.
So at the end I was forwarding to that jsp..
Should I not have a forward int he action class?If so how do I achieve that.
Thanks

You can either send the excel file or redirect the user, not both.
You're getting the error because once you've sent the excel file,
you're trying to send the redirect but the stream has already been
used.
