Hi All;
Trying to get a FOP demo off the ground. The idea is an FO document comes in
from memory and is rendered to a PDF on the hard disk of the server.
Just to get things going I am working with a FO file on the hard drive as
well. I will tackle the contents of this file submitted in memory next.
Below is my code.
When I run it in IE it get a Pop up message telling me the "File does not
begin with '%PDF-'". This is weird to me because I am not trying to send it
back through the response object, I don't know why the browser is even
looking at it.
When I run it in FireFox I get my success message printed, and the document
created. However when I trying and open it I am told there is a Sharing
Violation. The writer was closed before I printed the success statement so I
am not sure where the conflict came from.
Is there a better, smarter or easier way to do this? Any help would be
appreciated.
Thanks,
Luke
