http://nagoya.apache.org/bugzilla/show_bug.cgi?id=14493 POI --- Invalid Header signature ------- Additional Comments From [EMAIL PROTECTED] 2004-01-16 04:41 ------- 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. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
