It will not be empty. It seems there is some misunderstanding here. Of cource a ResourceAsStream InputStream has no file backed (or the file is not easy reachable). The main idea behin TikeInputStream is to provide the file on request. If hasFile() returns false, TikaInputStream will do the following when you call getFile(): - create temporary file - copy the whole stream to the temporary file After that you can process the contents. If the InputStream passed to TikaInputStream has a possibility to get the file backed, it will return it directly, but in most cases it will create a temporary one and copy the contents into it. Because of this its always better to make your parser work on a InputStream and only use a file, if the parser cannot (e.g. because it needs random access). > So basically, my file is converted to InputStream by > > InputStream stream = HWPParserTest.class.getResourceAsStream( > "/test-documents/testHWP.hwp"); > > After that, InputStream stream is passed to parser() of HWPParser and it should > be converted to TikaInputStream tstream without the loss of input file data. > I'm currently doing > > TikaInputStream tstream = TikaInputStream.get(stream); > > right now. > I believe tstream.hasFile() should true right away in order to my parser class to > work. No, hasFile only tells you if the wrapped InputStream has a backing file, for resource streams this is not the case. If you cann getFile() it will emulate a backing file by copying to a temporary one.
