MultipartEntity and HttpMultipart
Hi,
Using HTTP components 4.0 I wanted to create a POST request using the
multipart/mixed content type. However the MultipartEntity does not allow
the contentType to be set and is hardcoded to multipart/form-data.
Looking through the API it looks as though the HttpMultipart class (and
its associated classes) are available to address the various multipart
media types, however it appears to be incompatible with HttpPost addPart
method as HttpMultipart does not implement the HttpEntity interface. I
could not locate an obvious class used for request handling for
"HttpMultipart"-based requests. It appears the simplest means to POST a
request with multipart/mixed contentType is to create a new entity class
implementing HttpEntity (e.g. MultipartMixedEntity) - is that correct or
are there other means of doing this with the 4.0 API?
Also, what is the relation between these sets of entity classes - the
HttpEntity implentations appear in the "entity" package and the others
appear in the "mime" package? Is there some sort of de-lineation or
usage rules for these classes I should be aware of?
Thanks.
Scott.

I agree with Oleg, I have done as he says, I have extended the
MultipartMime class and overridden one or two methods. I remember there
were some issues with setting and getting the content type, I don't know
if that has been fixed or not.

Hi Oleg,
Yes, that answers my question, thanks.

You will be better off just overriding the #generateContentTypre method
of the MultipartEntity class.

HttpMime is somewhat special because it is not fully API stable due to
its dependency on Mime4j, which is still considered API unstable.
Hope this answers your question.
