Re: need help to change charset when fileUpload using MultipartPostMethod

[Oleg Kalnichevski <ol...@apache.org>]

Bülent,

This is a well known issue. The problem is that the use of non-ASCII
characters in the content disposition header (the one that includes the
file name attribute) violates the MIME spec.

See the following bug reports for details

http://nagoya.apache.org/bugzilla/show_bug.cgi?id=30420
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=24504

You can work the problem around by

(1) sub-classing FilePart and providing a custom implementation of the
sendDispositionHeader(OutputStream) method

(2) using Q-Codec to encode the file name

http://jakarta.apache.org/commons/codec/apidocs/org/apache/commons/codec/net/QCodec.html

Hope this helps

Oleg
