Hi As the creation of document is 3 step process. I am having two different apis- Batch Creation and Create metadata(document) ——> Wrapper on nuxeo created with spring rest template and uploading image in 2nd step directly to nuxeo with out wrapper——>working fine.

I am also having another api which does all 3 steps in one method in wrapper java sdk But then the image is not visible. and getting “picture:info”: {

        "colorSpace": null,
        "depth": null,
        "width": null,
        "format": null,
        "height": null
    },  in response

For reference attaching two responses and code for uploading image:- //sending file as form data using postman public HttpResponse upload(String url, String fileName, String caseId, MultipartFile file, String batchId,

                           int index, HttpHeaders headers) {
    File tmpFile = null;
    try {
        HttpClient httpclient = HttpClientBuilder.create().build();
        HttpPost httppost = new HttpPost(url);
        for (Map.Entry<String, List<String>> header : headers.entrySet()) {
            if (header.getKey().equalsIgnoreCase("Content-Length")) {
                continue;
            }
            httppost.setHeader(header.getKey(), header.getValue().get(0));
        }
        httppost.setHeader(DmsConstants.CONTENT_TYPE, MediaType.APPLICATION_OCTET_STREAM_VALUE);
        //Writing multi-part file in temporary file
        tmpFile = new File(fileName + "_" + caseId + "_" + UUID.randomUUID().toString()); //UUID added so two requests do not over-write same file
        file.transferTo(tmpFile);
        httppost.setHeader(DmsConstants.X_FILE_NAME, tmpFile.getName());
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        builder.addBinaryBody("file", tmpFile, ContentType.DEFAULT_BINARY, tmpFile.getName());
        // 
        HttpEntity entity = builder.build();
        httppost.setEntity(entity);
        // execute the request
        HttpResponse response = httpclient.execute(httppost);
        LOGGER.info("response from upload file: {}", response);
        return response;

}
