Making HTTP POST call in Java with file

Question

I am trying to make a HTTP POST call to upload a file (and also has to fill parameters ex. title) to restful web service:

This is what I tried to do:

    File file = new File(filepath);

    HttpClient client = new DefaultHttpClient(); //DefaultHTTPClient is deprecated?
    HttpPost post = new HttpPost(url);

    //Multipart Entity is also deprecated?? 
    MultipartEntity entity = new MultipartEntity();
    entity.addPart("file[path]", new FileBody(file));
    post.setEntity((HttpEntity) entity);

    try {
        HttpResponse response = client.execute(post);

    } catch (IOException e) {

        e.printStackTrace();
    }

This is not working. I am not sure how to upload the file and add the parameters and make the call? I tried this using Java Http Client to upload file over POST but the ones he/she used is deprecated? I have httpcore 4.4 alpha jar

Yes the classes you use are deprecated. Try this example:

I have a question MultipartEntityBuilder.create() .addPart("bin", bin) .addPart("comment", comment) .build(); What are these parts thats being added? Is that the parameters? – Raj kobie Aug 29 '14 at 22:36
To which restfull service are you trying to upload to? – Filip Nguyen Aug 29 '14 at 22:37
A custom one given to me. It has the ability to accept files and the service part works – Raj kobie Aug 29 '14 at 22:42
