Hi Benson
AFAIK multipart/form-data is mainly used to submit files from the forms [1],
though individual parts may contain "application/x-www-form-urlencoded"
data, this is my interpretation at least and this is how I implemented the
way multipart/form-data is handled. So it should really be :
@Consumes("multipart/form-data")
public Response addGazetteer(@FormParam("gazetter") String gazetteer) {
}
in other words CXF FormProvider will not delegate to other providers
(JAXB/JSON, etc) when dealing with "multipart/form-data"; perhaps it should
?
It is MultipartProvider which deals with multipart/related, multipart/mixed,
etc, which will delegate. It is this provider which will notice
@Multipart(type = "application/json").
There's a couple of options. If you can actually afford specifying say
multipart/mixed then it will work as expected. Another option is to register
a simple RequestFilter impl which will change multipart/form-data
to say multipart/mixed. Finally you can do
@Consumes("multipart/form-data")
public Response addGazetteer(@FormParam("gazetter") Gazetter gazetteer)
{
}
and register a ParameterHandler<Gazetter> which will use a JSONProvider to
convert a JSON sequence into Gazetter
cheers, Sergey
