Magic mime type detection support
---------------------------------

                 Key: JBSEAM-1879
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1879
             Project: JBoss Seam
          Issue Type: Feature Request
          Components: Core
            Reporter: Christian Bauer
            Priority: Minor

A component I can call to find out what mime type a particular byte[] or ByteInputStream is. The only existing solution in Java is http://sourceforge.net/projects/jmimemagic/ but it's basically an unmaintained half-working pile of junk. 

It's interesting that nobody ever build a simple port of file(1), which you get on every unix box, together with a fantastic (/etc/magic or /usr/share/file/magic on the Mac) database of magic bytes found in file headers. We should just take that database (or the source database from which it is generated) and write our own file(1) for Seam. Search for "mime magic java" with Google and you see why it's needed. Try "file myfile.foo" on every unix box (well, younger than 10 years) and you see how it works.
