I encountered this same error.  I was using an excel document as a template for
generating an excel report via the web.  The webserver threw the same exception
so I copied the template from my build tree to /tmp and stripped down my jsp
page to a bare essentials java class and it worked. So, I then executed a diff
on my xls file in my build directory and the one deployed by weblogic and they
differed!

I'm using ANT to handle my building and packaging.  I mistakenly added filtering
 to a copy task that included my excel files.  That was enough to corrupt my xls
files.   After splitting out the xls files from the filtered copy task all is well.

Well, I just wanted to comment on my mistake to hopefully help others down the road.
Thanks.
