: However, when I convert InputStream stream (inside parse function) to File, : it seems that Solr is adding header and footer that contains Metadata so the : file won't be converted properly.
... It's not totally clear from your problem description, but i *think* you are saying that you are using SolrJ to stream these special XML files you created to Solr, and then ou are using a custom parser registered with Tika/ExtractingRequestHandler to parse them into documents. The output you've pasted below appears to be a HEX dump of the raw HTTP stream from this communicaiton. Solr isn't adding any header/footer to your XML files, what you are seeing are the normal HTTP headers added to a file when using MIME to send multiple files. You may also occasically notice "chunked encoding" markers used to stream arbitrary amounts of data over HTTP w/o requiring the clients to pre-calculate the total "Content-Length". This is all happening at the HTTP protocol level, and will be dealt with by the HttpClient and Servlet Container before Solr ever sees the InputStreams -- let alone hands them to Tika -- so it should be completley transparent to you (unless you go sniffing the wire like this) If you are encountering an actual problem, then you need to give us a lot more details about how you are using SolrJ/Solr, what servlet container you are using, what your custom parser code looks like, and what kind of errors you are getting, so someone can try to reproduce the problem. : Following text is added as a header : : 1 0000000: 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d ---------------- : 2 0000010: 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d 3139 --------------19 : 3 0000020: 3230 3862 3937 3764 6637 0d0a 436f 6e74 208b977df7..Cont : 4 0000030: 656e 742d 4469 7370 6f73 6974 696f 6e3a ent-Disposition: : 5 0000040: 2066 6f72 6d2d 6461 7461 3b20 6e61 6d65 form-data; name : 6 0000050: 3d22 6d79 6669 6c65 223b 2066 696c 656e ="myfile"; filen : 7 0000060: 616d 653d 2268 7770 322e 6877 7022 0d0a ame="hwp2.hwp".. : 8 0000070: 436f 6e74 656e 742d 5479 7065 3a20 6170 Content-Type: ap : 9 0000080: 706c 6963 6174 696f 6e2f 6f63 7465 742d plication/octet- : 10 0000090: 7374 7265 616d 0d0a 0d0a d0cf 11e0 a1b1 stream : : : Following text is added as a footer : : 554 0002290: 0000 0000 0000 0000 0000 0d0a 2d2d 2d2d ............---- : 555 00022a0: 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d 2d2d ---------------- : 556 00022b0: 2d2d 2d2d 2d2d 2d2d 2d2d 3139 3230 3862 ----------19208b : 557 00022c0: 3937 3764 6637 2d2d 0d0a 977df7--.. -Hoss
