public class PortletFileUpload 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(javax.servlet.http.HttpServletRequest)
to acquire a list ofFileItems
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.
