Re: PDF parser exception

Hi all,

I'm new to Tika and to this mailing list, so I hope this is the right
place to ask this question.

I've just downloading, built and installed Tika 0.5. I've been able to
translate Microsoft Office documents without any problems. However,  
when
I try to translate a PDF file, I get a parser exception.

Is this the case with any and all PDF files?

Based on the stack trace below, it sure looks like a busted file, but  
I've mostly been working with the HTML parser.

The command line I'm running is:

 % java -jar tika-app/target/tika-app-0.5.jar foo.pdf

The resulting exception output is:

Exception in thread "main" org.apache.tika.exception.TikaException:

Can someone help point me to a way to solve this problem? I'm familiar
with Java but not the PDF format or how Tika parses a document.

Please let me know if there is a better forum to ask this question, or
if I need to provide more information.


TIA,

Doug
