Mime types supported are defined in a ressource file inside the activation.

This method is interesting when you need to deal with incoming files with the filenames normalized. The result is very fast because only the extension is used to guess the nature of a given file.

Like the above method a match is done with the mimetyesfiletypemap. A note from R. I was trying to find the best way of getting the mime type of a file and found your sight very useful.


However I have now found a way of getting the mime type using URLConnection that isn’t as slow as the way you describe. Using Apache Tika Tika is subproject of Lucene, a search engine. It is a toolkit for detecting and extracting metadata and structured text content from various documents using existing parser libraries.

Tika has a lot of dependencies But it can do a lot more than detecting filetype. For example, you can parse a PDF to extract the text and the metadata very easily. You can download here a ZIP containing the required jars if you mimetypesfiletypdmap to check it out.

Using JMimeMagic Checking the file extension is not a very strong way to determine the file type. A more robust solution is possible with the JMimeMagic library.
