I haven't had time to look into the specifics, but I can tell by the error you posted that your PDF is "non-conforming" (aka it violates the PDF specification... it's not a valid PDF). This isn't to say that some programs won't be able to read it anyway, but that's the root cause of this error. Specifically, it looks like there's an "endobj" line which is missing. If I have some extra time, I'll debug through it and see exactly what section of the PDF is corrupt.
If you can, go ahead and create an issue on JIRA[1] and attach this file. One of our goals is to make PDFBox be able to read non-conforming PDFs as best it can without throwing an exception; this PDF could serve as a good example on some things we need to watch out for. [1] https://issues.apache.org/jira/browse/PDFBOX ---- Thanks, Adam From: Alex Rodriguez Lopez <[email protected]> To: [email protected] Date: 12/07/2010 08:28 Subject: org.apache.pdfbox.io.PushBackInputStream on some PDFs Hi list! I'm using PdfBox through Apache TIKA 0.8 and it gives me an error on some files when parsing, the resulting file (after the exception is raised) is a partial text extraction, like text from some pages at the beginning followed by text from the end of the PDF, missing pages at the middle... Is happens only in some files, for example (~2MB): http://biblioteca.sinbad.ua.pt/DisQSws/get.aspx?filename=2010001615.pdf&catalog=Teses&type=pdf It happens when called from a webapp as well as when called from the command line: java -jar tika-app-0.8.jar -t < input.pdf > extracted.txt I have tried with different heap sizes too. I'm getting: WARN - Parsing Error, Skipping Object java.io.IOException: expected='endobj' firstReadAttempt='' secondReadAttempt='' org.apache.pdfbox.io.pushbackinputstr...@53ab04 at org.apache.pdfbox.pdfparser.PDFParser.parseObject(PDFParser.java:607) at org.apache.pdfbox.pdfparser.PDFParser.parse(PDFParser.java:172) at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:878) at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:843) at org.apache.tika.parser.pdf.PDFParser.parse(PDFParser.java:74) at org.apache.tika.parser.CompositeParser.parse(CompositeParser.java:197) at org.apache.tika.parser.CompositeParser.parse(CompositeParser.java:197) at org.apache.tika.parser.AutoDetectParser.parse(AutoDetectParser.java:137) at org.apache.tika.cli.TikaCLI.process(TikaCLI.java:218) at org.apache.tika.cli.TikaCLI.main(TikaCLI.java:84) What does this error means? Can somebody tell if there is something wrong with the pdfs I'm giving PDFBox? I thing this is most probably the case, but then what's wrong with the file I linked to at the beginning?
