Below is the code for uploading a (potentially large) file with chunked transfer encoding (i.e. streams) using Jersey 2.11.

Maven:

    2.11



    
        org.glassfish.jersey.core
        jersey-client
        ${jersey.version}
    
    
    org.glassfish.jersey.media
        jersey-media-multipart
        ${jersey.version}
    

Java:

Client client = ClientBuilder.newClient(clientConfig);
client.property(ClientProperties.REQUEST_ENTITY_PROCESSING, "CHUNKED");

WebTarget target = client.target(SERVICE_URI); 
InputStream fileInStream = new FileInputStream(inFile);
String contentDisposition = "attachment; filename=\"" + inFile.getName() + "\"";
System.out.println("sending: " + inFile.length() + " bytes...");
Response response = target
            .request(MediaType.APPLICATION_OCTET_STREAM_TYPE)
            .header("Content-Disposition", contentDisposition)
            .header("Content-Length", (int) inFile.length())
            .put(Entity.entity(fileInStream, MediaType.APPLICATION_OCTET_STREAM_TYPE));
System.out.println("Response status: " + response.getStatus());
