An update for those trying to use MultipartEntity...

org.apache.http.entity.mime.MultipartEntity is deprecated in 4.3.1.

You can use MultipartEntityBuilder to create the HttpEntity object.

File file = new File();

HttpEntity httpEntity = MultipartEntityBuilder.create()
    .addBinaryBody("file", file, ContentType.create("image/jpeg"), file.getName())
    .build();

For Maven users the class is available in the following dependency (almost the same as fervisa's answer, just with a later version).

  org.apache.httpcomponents
  httpmime
  4.3.1
