[Zope-dev] TextIndexNG and ExternalFile

[biddu_d]

Hello,
I am using TextIndexNG and ExternalFile to index documents. I am able 
to index all documents that are in the ZODB and also pdf files in a 
LocalFS directory. However, the indexing fails for pdf documents 
setup as External Files.
Am I missing anything in the setup? Incidentally, it is able to index 
ExternalFile text documents, only the pdf files have a problem. Any 
help would be appreciated.
Setup is on Linux. Converter is xpdf.
Regards/Biddu
