Nick Burch commented on TIKA-653:
---------------------------------
If you have a File object, then using a TikaInputStream might well be a better
bet for you
However, the exception you're getting does look like a problem with the
file/os, rather than Tika...
> Can't detected MimeType from FileInputStream

> Project: Tika
> Issue Type: Bug
> Affects Versions: 0.9
> Reporter: Sascha Rodekamp
>
> Hi,
> i have a problem with the detection of the mime type from an file input
> stream.
> It always throws an IO Exception. I tried to wrap the FileInputStream in a
> BufferedInputStream because the BIS but it doesn't help. Here the Stack Trace:
> {code}
> Exception: java.io.IOException
> Message: Read error
> ---- stack trace
> ---------------------------------------------------------------
> java.io.IOException: Read error
> java.io.FileInputStream.readBytes(Native Method)
> java.io.FileInputStream.read(FileInputStream.java:199)
> java.io.BufferedInputStream.fill(BufferedInputStream.java:218)
> java.io.BufferedInputStream.read1(BufferedInputStream.java:258)
> java.io.BufferedInputStream.read(BufferedInputStream.java:317)
> java.io.FilterInputStream.read(FilterInputStream.java:90)
> org.apache.tika.mime.MimeTypes.readMagicHeader(MimeTypes.java:300)
> org.apache.tika.mime.MimeTypes.detect(MimeTypes.java:535)
> org.apache.tika.Tika.detect(Tika.java:132)
> org.apache.tika.Tika.detect(Tika.java:155)
> {code}
> It works great with a ByteArrayInputStream.
> MyCode to get the MimeType from the InputStream is:
> {code}
> if (!is.markSupported()) {
> is = new BufferedInputStream(is);
> }
> Tika tika = new Tika();
> try {
> return tika.detect(is);
> }
> .....
> {code}
> Is this a bug in the library or my fault?
> any help would be great:)
