Hi Arthi,
I should have noticed this in my first response. When sending binary
document you need to use the "--data-binary @{file}" instad of
"--data" as "--data" is a shorthand for "--data-ascii". I made a short
test on
http://dev.iks-project.eu:8081/enhancer/chain/dbpedia-proper-noun
with "--data" and a PDF document and got an empty response. WIth
"--data-binary" I got the expected results.
If this does not solve your problems you should try to remove the
"optional" flag from the "tika" engine in your chain, because this
would cause the enhancement process to fail in such cases. If "tika"
is marked as optional errors are only logged and the processing is
continued.
We had some some issues with the Tika engine related to XML based
office documents (e.g. STANBOL-810, STANBOL-970) but as PDF files do
also not work for you I expect that your issues are caused by
something different.
Feel free to test also on the dev.iks-project.eu server. e.g.
http://dev.iks-project.eu:8081/enhancer
http://dev.iks-project.eu:8081/enhancer/chain/dbpedia-proper-noun
best
Rupert
