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
