http://hc.apache.org/httpcomponents-client-4.3.x/httpmime/examples/org/apache/http/examples/entity/mime/ClientMultipartFormPost.java

import org.apache.http.entity.mime.MultipartEntityBuilder;

HttpPost httppost = new HttpPost("http://localhost:8080" +
        "/servlets-examples/servlet/RequestInfoExample");

FileBody bin = new FileBody(new File(args[0]));
StringBody comment = new StringBody("A binary file of some kind", ContentType.TEXT_PLAIN);

HttpEntity reqEntity = MultipartEntityBuilder.create()
        .addPart("bin", bin)
        .addPart("comment", comment)
        .build();


httppost.setEntity(reqEntity);
