Hi, It's usual behavior for any function that consumes stream (it's not Tika related). In this case you can wrap it with BufferedInputStream, since detection needs only beginng of the file.
Code snippet is: InputStream bis = new BufferedInputStream(inputsbust); tika.detect(bis); Tika resets stream after use, so buffered input stream can be used again. -- Best regards, Konstantin Gribov Thu Jan 29 2015 at 18:16:32, Gabriele Guidi <gabriele.gu...@eng.it>: Thanks for your answer. > I had the same behaviour with tika 1.6 and 1.5. > I found a workaround, the problem seems to happen with only InputStream, so > now I use byte[] and it's OK. > > Thanks again > Il 29/gen/2015 07:24 "Mattmann, Chris A (3980)" < > chris.a.mattm...@jpl.nasa.gov> ha scritto: > > > Dear Gabriele, > > > > Thanks for your question.
