public class ServletFileUpload
- extends FileUpload
High level API for processing file uploads.
This class handles multiple files per single HTML widget, sent using multipart/mixed
encoding type, as specified by RFC 1867. Use
parseRequest(HttpServletRequest)
to acquire a list of FileItem
s associated with a given HTML widget.
How the data for individual parts is stored is determined by the factory used to create them; a
given part may be in memory, on disk, or somewhere else.
