Please find below jersey client code to upload multipart file:

String url = "http://localhost:7070"
Client client = Client.create();
WebResource webresource = client.resource(url);
File file = new File("C://Data//image1.jpg");
File thumbnail = new File("C://Data/image2.jpg");


InputStream isthumbnail = new FileInputStream(thumbnail);
InputStream isfile = new FileInputStream(file);

FormDataMultiPart multiPart = new FormDataMultiPart();
FormDataBodyPart bodyPart1 = new FormDataBodyPart(FormDataContentDisposition.name("Thumbnail").fileName("thumbnail").build(), isthumbnail, MediaType.APPLICATION_OCTET_STREAM_TYPE);
FormDataBodyPart bodyPart2 = new FormDataBodyPart(FormDataContentDisposition.name("File").fileName("file").build(), isfile, MediaType.APPLICATION_OCTET_STREAM_TYPE);
multiPart.bodyPart(bodyPart);
multiPart.bodyPart(bodyPart1);

//New Headers
String fileContentLength = "form-data; contentLength=\""+Long.toString(file.length())+ "\"";
String thumbnailContentLength = "form-data; contentLength=\""+Long.toString(file.length())+ "\"";

final ClientResponse clientResp = webresource.type(MediaType.MULTIPART_FORM_DATA_TYPE).accept(MediaType.APPLICATION_XML).post(ClientResponse.class, multiPart);
System.out.println("File Upload Success with Response"+clientResp.getStatus());

I need to add the String fileContentLength and thumbnailContentLength as header Content-Length. How do i add the headers as part of multipart and post the request?Any help would be appreciated

Use a FormDataContentDisposition as an argument to FormDataBodyPart(FormDataContentDisposition formDataContentDisposition, Object entity, MediaType mediaType).

final FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
final String value = "Hello World";
final FormDataContentDisposition dispo = FormDataContentDisposition
        .name("file")
        .fileName("test.txt")
        .size(value.getBytes().length)
        .build();
final FormDataBodyPart bodyPart = new FormDataBodyPart(dispo, value);
formDataMultiPart.bodyPart(bodyPart);
