Jeremias Maerki resolved PDFBOX-1467.
-------------------------------------
Resolution: Not A Problem
I've just stumbled over the same problem with a different PDF. What the two
have in common: they are encrypted. So I assume that you didn't decrypt the
document. After adding the following code right after loading the PDF, it works
now for me:
{code}
String password = "";
if (doc.isEncrypted()) {
try {
doc.decrypt(password);
} catch (InvalidPasswordException e) {
System.err.println("Invalid password for encrypted
document.");
} catch (CryptographyException e) {
throw new IOException("Error decrypting PDF document: " +
e.getMessage(), e);
}
}
{code}
> PDocumentCatalog.getAllPages returns empty list for certain pdfs, affects
> many other methods as well

> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 1.7.1
> Reporter: Peter Lehto
> Priority: Critical

> Originally found from PageExtractor and after some debugging, it seems that
> PDocumentCatalot.getAllPages returns an empty list for certain pdfs. Also
> calling PDDocument.getNumberOfPages returns 0 as it uses the catalog for
> getting the actual information. This goes all the way down to
> COSDictionary.getDictionaryObject, which returns null for COSName.PAGES.
> Eventually everything that has something do with page numbers fails. For
> example saving document to stream etc.
> This problems occurs with certain pdf documents. I suspect they have some
> kind of different structure or header information or possibly even corrupted
> header. With other pdf files this problem does not exist. The non working pdf
> files are still accessible through other software like Adobe Reader and they
> work.
