public class Mimetypes
extends java.lang.Object
This class is obtained with the {#link getInstance()
method that
recognizes loaded mime types from the file mime.types
if this
file is available at the root of the classpath. The mime.types file format,
and most of the content, is taken from the Apache HTTP server's mime.types
file.
The format for mime type setting documents is:
mimetype
. Any
blank lines in the file are ignored, as are lines starting with
#
which are considered comments. Lines that have a mimetype but
no associated extensions are also ignored.
