There was a need to retrieve images from external sites, so after some research, I thought that Tika would do the trick. I had preferred content type detection via
magic numbers over file extension only. Unfortunately, the library had a very long list of dependencies. Jetty didn't complain, but the moment I deployed the WAR file on to Wildfly, it encountered a whole bunch of problems, including
this. I didn't think the headache was worth the it and sought for an alternative. Google returned
this article which had a pretty comprehensive list of libraries. Despite the smaller footprint of
mime-util, I decided to go for the more recent
jMimeMagic (added TIFF support, last updated 12 Dec 2014, as of today) instead.
Magic parser = new Magic();
MagicMatch match = parser.getMagicMatch(new File("image.jpg"));
System.out.println(match.getMimeType());
That's all there is to using it.
At least Wildfly accepted the new WAR file. We'll have to continue monitoring the situation for this.
