public DssResponse callPut(String url, Map headers, FileDataBodyPart[] filePath, String boundary, String[] jsonString) throws IOException {
    Client client = ClientBuilder.newClient().register(MultiPartFeature.class);
    WebTarget webTarget = client.target(url);
    Builder builder = webTarget.request(MediaType.MULTIPART_FORM_DATA);
    FormDataMultiPart multiPart = new FormDataMultiPart();
    for (int i = 0; i < filePath.length; i++) {

        if (!filePath[i].getFileEntity().exists()) {
            throw new IOException("Invalid Input File - " + filePath[i].getFileEntity().getAbsolutePath());
        }

        multiPart.bodyPart(new FileDataBodyPart(filePath[i].getName(), filePath[i].getFileEntity()));
    }

    if (boundary != null)
        multiPart.type(Boundary.addBoundary(new MediaType("multipart", "form-data", Collections.singletonMap(Boundary.BOUNDARY_PARAMETER, boundary))));
    for (String jstr : jsonString) {
        multiPart.field("Content-Type", jstr, MediaType.APPLICATION_JSON_TYPE);
    }
    if (headers != null) {
        for (Entry header : headers.entrySet()) {
            builder.header(header.getKey(), header.getValue());
            System.out.println(header.getKey() + "===============>>" + header.getValue());
        }
    }

    Response response = builder.accept(MediaType.APPLICATION_JSON).put(Entity.entity(multiPart, multiPart.getMediaType()));

    multiPart.close();

    // Assert.assertNotNull(response);
    if (response == null )
        throw new IOException ("Response is NULL");

    int status = response.getStatus();

    return dssResponse;
}
