I'm having some issues when I attempt to parse pdf and docx files while using
ForkParser. I finally figured out how to get the metadata from the content
handler using ToXMLContentHandler, but I am not getting any results when I
parse pdfs or DocX files using ForkParser. I have copy and pasted the error
and stack trace below, but I believe this only applies to PDF files as I am not
getting a unique error for DocX files.
I did a little searching, using java's jar utility to verify that the class
shows up in the Jar and it does. I was previously using the AutoDetectParser
and that was working just fine with the exception that I could not limit tika's
memory usage, so this seems to be unique to ForkParser.
Thanks,
