MimeTypeHelper Class

public class MimeTypeHelper

    extends Object

Utility class to help with Mime Types.

This provides support for determining the MIME type based upon a file path/extension, and determining the extensions for a MIME type.

Upon load, this class will attempt to load in the "mime.types" in the same package as it (as a resource via getResource()). If that fails, an error will be thrown. The "mime.types" file should be of the standard Apache group format and provides information on most public mime types.
