Just to finish this thread off nicely, here's some code to use
multipart posts. Again, you need mime4j, httpmime, and Apache Commons
IO.
import java.io.ByteArrayInputStream;
import java.io.InputStream;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.ContentBody;
import org.apache.http.entity.mime.content.InputStreamBody;
import org.apache.http.entity.mime.content.StringBody;
import org.apache.http.impl.client.DefaultHttpClient;
...
HttpClient httpClient = new DefaultHttpClient();
HttpPost request = new HttpPost("http://www.example.com";);
// we assume 'data' is some byte array representing a jpeg
InputStream ins = new ByteArrayInputStream(data);
parts[0] = new InputStreamBody(ins, "image.jpg");
parts[1] = new StringBody("some bit of information");
parts[2] = new StringBody("another bit of information");
// create the multipart request and add the parts to it
MultipartEntity requestContent = new MultipartEntity();
requestContent.addPart("image.jpg", parts[0]);
requestContent.addPart("data_part1", parts[1]);
requestContent.addPart("data_part2", parts[2]);
// execute the request
request.setEntity(requestContent);
httpClient.execute(request);
The HttpClient execute method will give you a handle to the response.
>From that you can do HttpResponse.getEntity().getContent() which will
give you an InputStream to read the response. Unfortunately the
InputStream doesn't produce a meaningful response for
InputStream.available(). This might be because somewhere along the way
the Content-Length header seems to be getting lost, but I haven't had
time to look into this further yet.
