FYI,
I have just tested with iText-2.1.7.jar and the problem is resolved!
Thanks,
Daniel

TvT,
Thanks for the detailed response. Attached is the problematic pdf file that
the customer has allowed me to share.
I will also try a newer version to see if that fixes the issue.
I don't have Adobe Acrobat, but a colleague does so I will ask him to run
Preflight on the pdf file.
Thanks,
Daniel

Two possibilities:
1. You are using an quite old version of iText and maybe that was a bug
fixed a long time ago?
2. Your PDF is not (fully) PDF spec compliant
(3. possible but not probable: iText has a bug and your PDF is running into
it)
Opening a PDF in Adobe Reader doesn't say anything except it may be some
sort of PDF file you are trying to open. Adobe Reader is like IE back in the
days - opening any crap HTML page guessing their authors intent. You can now
try the following three things:
1. provide the PDF and we can tell you more. If it is a customer PDF and you
are not able to share then
2. try a newer version of iText (2.1.7 for less changes in your code and/or
5.4.4 the most up-to-date version) and see whether the problem still exists
3. Do you have an Adobe Acrobat at hand? If so run Preflight (Check PDF
Syntax Errors and PDF/A-1b compatibility. Even if your PDF may not be a
PDF/A document this test is in many cases better to detect general PDF spec
problems then the syntax check)

TvT

Hi,
We're using the iText-2.1.2u.jar version to generate flattened pdf forms
with additional pdf files inserted. The following code illustrates how the
additional pdf files are inserted:
...
// read pdf attachment
InputStream is = getFileInputStream(con, diu);
if (is == null)
{
return;
}
PdfReader docReader = new PdfReader(is);
// note: pdf pages start with 1, not 0
for (int p = 1; p <= docReader.getNumberOfPages(); p++)
{
copy.addPage(copy.getImportedPage(docReader, p));
}
docReader.close();
is.close();
...
Our customer is having trouble with inserting a pdf file that was generated
from scanning a document into a pdf file. The "new PdfReader(is)" line
above keeps generating the exception below. I've searched online for the
cause of this error and learned that it's because the file is not ended
properly or is somehow corrupt, but I am able to open the pdf file just fine
with Adobe Reader; furthermore, I compared the ending of the file with other
pdf files that work just fine (using a text editor), and don't observe any
differences. Does anyone know how to resolve this issue?
Thanks,
Daniel
