public class: MimetypesFileTypeMap [javadoc | source]
java.lang.Object
   javax.activation.FileTypeMap
      javax.activation.MimetypesFileTypeMap
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:

  1. Programmatically added entries to the MimetypesFileTypeMap instance.
  2. The file .mime.types in the user's home directory.
  3. The file <java.home>/lib/mime.types.
  4. The file or resources named META-INF/mime.types.
  5. 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"

 public synchronized  void addMimeTypes(String mime_types) 
    Prepend the MIME type values to the registry.
 public String getContentType(File f) 
    Return the MIME type of the file object. The implementation in this class calls getContentType(f.getName()).
