Subject RE: [FileUpload] Corrupted uploaded binary (MS Excel) file
Date Tue, 29 Jun 2004 02:52:09 GMT
I tried using the inputStream from the fileItem and writing the contents to a File, but the
result is the same - file is still corrupted.
 
I dont know how to use the inputStream from the request directly as there are HTML headers
in the stream.

	Have you tried reading this in via an input stream and writing out via an
	output stream.
