Class MimetypesFileTypeMap

  javax.activation.FileTypeMap
      javax.activation.MimetypesFileTypeMap

public class MimetypesFileTypeMap
extends FileTypeMap

This class extends FileTypeMap and provides data typing of files via their file extension. It uses the .mime.types format.

MIME types file search order:

The MimetypesFileTypeMap looks in various places in the user's system for MIME types file entries. When requests are made to search for MIME types in the MimetypesFileTypeMap, it searches MIME types files in the following order:

Programmatically added entries to the MimetypesFileTypeMap instance.
The file .mime.types in the user's home directory.
The file <java.home>/lib/mime.types.
The file or resources named META-INF/mime.types.
The file or resource named META-INF/mimetypes.default (usually found only in the activation.jar file).

MIME types file format:

# comments begin with a '#' # the format is <mime type> <space separated file extensions> # for example: text/plain txt text TXT # this would map file.txt, file.text, and file.TXT to # the mime type "text/plain"
