title: RestEasy client framework file upload
body: <p>Does anyone know how to create the RestEasy client side calls to upload a file using the following two interface signatures? I'm not finding any information at all. I know how to do it using the HttpClient but I'd like to use the client proxy to keep it consistent.</p>
  
  <pre><code>@POST
  @Path("/upload")
  @Consumes("multipart/form-data")
  public void uploadFile(MultipartFormDataInput input);
  
  @POST
  @Path("/upload2")
  @Consumes("multipart/form-data")
  public void uploadFile2(@MultipartForm FileUploadForm form);
  </code></pre>
  
  <p>Any help would be appreciated,
  Fredrik</p>
