ClassCastException in FlateFilter
---------------------------------
Key: PDFBOX-354
URL: https://issues.apache.org/jira/browse/PDFBOX-354
Project: PDFBox
Issue Type: Bug
Components: Text extraction
Reporter: Jukka Zitting
[Issue from SourceForge]
http://sourceforge.net/tracker/index.php?func=detail&aid=1965266&group_id=78314&atid=552832
Hi, I'm trying to extract text from a pdf which can be found at
http://www.vattenfall.com/www/vf_com/vf_com/Gemeinsame_Inhalte/DOCUMENT/360
168vatt/5965811xou/643131powe/892253fors/P0288421.pdf
and am getting a ClassCastException from within PDFBox. The full stacktrace
is:
java.lang.ClassCastException: org.pdfbox.cos.COSArray
at org.pdfbox.filter.FlateFilter.decode(FlateFilter.java:70)
at org.pdfbox.cos.COSStream.doDecode(COSStream.java:290)

at
011763f3ecc678d2org.pdfbox.util.PDFTextStripper.getText(PDFTextStripper.jav
a:149)
at [my code].
The code leading up to the call to extract text is as follows:
org.pdfbox.pdfparser.PDFParser parser = new
org.pdfbox.pdfparser.PDFParser(myInputStream);
parser.parse();
pdDocument = parser.getPDDocument();
setContent(new PDFTextStripper().getText(pdDocument));
I hope the formatting is ok! Have you encountered this error before and can
you suggest any causes or solutions?
Thanks,
Ben Kirby

Ben,
I just ran the PDF through our text extraction test -- without error.
I'm not sure what to say about the error you've encountered.
I do find that since version 0.73 came out Ben has updated the FlateFilter
source code. Have you tried the latest code or just the 0.73 build?

Hi Daniel, sorry for the delay in responding. I've only tried the 0.7.3
build - I'll grab the latest code build now, and let you kow how I get
on...
Thanks,
Ben

Hi again, sorry, but your 13/05 and 14/05 nightly build jar and zips seem
to be corrupt. Maven can't use the maven jars, and WinRAR throws an error
while opening all of them, zips and jars.
Am I doing something wrong, or are they corrupt?
Thanks,
Ben

Hi again. I've just checked back for a response, and as there isn't any,
have gone to try the nightly builds again. However there don't seem to be
any! I'm trying http://www.pdfbox.org/dist - have they moved? I really want
to get this fixed in our build, so please could let me know what's going
on.
Thanks,
Ben

In the near future, http://incubator.apache.org/projects/pdfbox.html will
be the place to look for PDFBox stuff.
I don't see nightly builds ... I'll see if I can find out about those.

Thanks Daniel - I came across the new site myself, but, you're right, I
couldn't see any nightly builds. If you could let me know what the plan is,
that'd be great, otherwise I'll check back next week.
Thanks for your help,
Ben
