I use MimetypesFileTypeMap and add any mime that is not there and I specifically need it, into mime.types file.įirst of all, MIME types list is huge, see here: ContentInfoUtil util = new ContentInfoUtil('/etc/magic') ĬontentInfo info = util.findMatch('/tmp/upload.tmp') ĬontentInfo info = util.findMatch(inputStream) ĬontentInfo info = util.findMatch(contentByteArray) if you want to use a different config file(s), you can load them by hand: With SimpleMagic you can do something like: // create a magic utility using the internal magic fileĬontentInfoUtil util = new ContentInfoUtil() I tried Apache Tika but it is huge with tons of dependencies, URLConnection doesn't use the bytes of the files, and MimetypesFileTypeMap also just looks at files names. It is designed to read and run the Unix file(1) command magic files that are a part of most ~Unix OS configurations. I've published my SimpleMagic Java package which allows content-type (mime-type) determination from files and byte arrays.
