File upload - binary file checksum issue

["Towns, Peter (ANTS)" <pe...@ants.co.uk>]

Hi,

I'm using Struts 1.0's multipart form functionality and it doesn't appear to
be correctly pulling binary content from the request to disk.

Using the sample 'struts-upload.war' app on NT, I've tried to upload & then
write a 600kb Word doc. The file successfully uploaded but the copied
version couldn't be opened by Word (since it was corrupted). The checksums
are different, and a hex dump clarified this - for example, the first diff
is 5452 ASCII chars into the file where an ASCII 65 ('e') becomes an ASCII
0A (a linefeed).

I tried to upload a PDF of equivalent size and the same behaviour occurred.
However, a text file upload was fine...

Has anyone experienced this ..? The linefeed is suspicious, but surely this
isn't a ASCII/binary issue since the multipart contents will just be base64
(or whatever) encoded/decoded prior/post transport ..?

Could this be a bug, or have I missed something ..?

Thanks,

Pete
