Hi Arul,
There is a silly bug in the multipart module. Can you log an issue.
However, i think this is orthogonal to the problem you are
encountering. HTTP headers are case insensitive, and Jersey will
anyway re-write the Content-Type header value to include the boundary
string parameter that declared the delimitation string between body
parts.
My suspicion is the CGI script cannot parse the value of the Content-
Type or Content-Disposition headers. But it would help if you could
get access to some sort of server-side information.
Developers have reported cases of services consume multipart/form-data
being sensitive to white space characters between parameters of media
types and content disposition types. Jersey does not use white space.
From Jersey:
Content-Disposition: form-data;name="file"
From Apache HTTP client:
Content-Disposition: form-data; name="file"
Paul.
