Hi there,
My users want also to be able to download Excel files generated on the fly by the application. For me, until now, it doesn't work at all on IE, Firefox does ask the user to download the file almost no matter what I do, but not IE. It keeps saying: "IE could not download doExport.jsf from localhost...."; (i've been trying all sort of combinations of mime types and content dispositions...)
I use a servlet to respond back with byte data and custom mime type. I redirect to something like /user/export/doExport.xls which is mapped to a servlet...Do you have any ideea about what could be wrong with this?
Is it possible to write a custom JSF component that performs the Excel generation and streaming? something like, for a dataTable when clicked generate an Excel file with the same columns and aks user to save...what will it take to make something like this? a custom renderer kit too?
Thanks,
Catalin

I've not experiencing this in firefox, so maybe is a IE only issue? I
am using the same code pattern,
