Portal 902. Uploaded document differs from downloaded document.

Question

We are currently trying to set-up a portlet, which would include items (documents, images etc.). The problem we faced in that process is related to portal's storing process. We uploaded a pdf-file (Java API Guide from otn.oracle.com) as a simple file. Then, attempting to open the same file from portal, we got different errors: "the file is damaged and could not be repaired", "error reading xref entry" etc. Since these errors refer to acrobat reader and browser conflict we turned that "open in browser" option off in Adobe Acrobat. After this, the situation did not improve. Still, it was possible to download the document from the portal as a file. We downloaded the file and made a binary comparison. The result was quite intereseting since the size of both (uploaded to portal and downloaded from portal) was the same (210 Kb) but the content was different. I will add also a excerpt from that downloaded file that differed from the initial file. How could we avoid similar problems in the future? Thank you.

Answer 1

I am having the exact same problem on 10.1.4. I have a pdf on my desktop which opens fine in Acrobat reader (v 7.0). I upload it to my portal page as a file and when I click on the link I get the "this file is damaged and cannot be repaired" message. I downloaded the portal version of the PDF and an extra 66 bytes had been added to it.
I only get this in my live environment as the file uploaded OK in user test. I have uploaded other PDF files and they can be viewed OK.
Has anyone come across and fixed this in the six years since the original post?
Thanks,
Steven.
