Your English is *much* better than my Japanese. ;-) Please refer to the FileUpload usage documentation, here:
http://jakarta.apache.org/commons/fileupload/using.html As you will see, you should be using the DiskFileUpload class, instead of the FileUpload class, if you want the default disk-based implementation. You should use the FileUpload class itself only if you need more control over the way in which FileItem instances are created. -- Martin Cooper On Fri, 21 Nov 2003, ume wrote: > How do you do. > > I am a Japanese.
