com.oreilly.servlet.multipart.FilePart
A FilePart is an upload part which represents a INPUT TYPE="file" form parameter. Note that because file upload data arrives via a single InputStream, each FilePart's contents must be read before moving onto the next part. Don't try to store a FilePart object for later processing because by then their content will have been passed by. @author Geoff Soutter @version 1.2, 2001/01/22, getFilePath() addition thanks to Stefan Eissing @version 1.1, 2000/11/26, writeTo() bug fix thanks to Mike Shivas @version 1.0, 2000/10/27, initial revision
