使用http'POST'从服务器端发送多个文件-发送FileInputStream的ArrayList

Question

I succesfully wrote an http 'post' that gets 1 file (image) from the server side like this:

@Path("getImage")
@POST @Produces({MediaType.APPLICATION_OCTET_STREAM})
public Response getImage(picRequest request)  throws Exception {
     File file = ......
       return Response.ok(new FileInputStream(file)).build();
}

And I check it using client:

ClientResponse response = webResource
            .type(MediaType.APPLICATION_JSON)
            .accept(MediaType.APPLICATION_OCTET_STREAM)
            .post(ClientResponse.class, inp);

The problem is that I cann't succeed when trying to send several files in a list. (ArrayList of FileInputStream)

ArrayList<InputStream> resultData = new  ArrayList<InputStream>();
while (rs.next()) {
    ....
    resultData.add(new FileInputStream(file));
}
  return Response.ok(resultData).build();

How do I do it? and what should be the MediaType?

Thank you so much for helping.

Consider returning a multipart/mixed response. Here is an blog describing how to do this with Jersey specifically.
