I want to send an array of files to the server, for this I convert files to base64 and send to an array. Here is how the array should look like:

"attach": [ {"filename": "preved.doc", "data": BASE64_FILE_ENCODED}, ... ]

and here is how I form it:

 {"attach":{"values":[]}

for some strange reason, I have an array of values ​​that I don’t need at all. Here is how I send the files to the array:

 ms.setArray(uploadFiles(new FileUpload(selected.getName(), readBytesFromFile(selected.getPath()))));

and here is the method:

 public JSONArray uploadFiles(FileUpload fileUpload) { JSONArray array = new JSONArray(); JSONObject object = new JSONObject(); try { object.put("attach", fileUpload); } catch (JSONException e) { e.printStackTrace(); } return array; }

everything seems to work as it should, well, that is, in base64 everything seems to be converted correctly, but then some strange magic happens. Maybe I am not forming the array in such a way, because I didn’t quite understand the difference between JSONArray and JsonArray, maybe I don’t use what I need. I hope for your help in solving this error.

    The problem was solved quite simply and I was honestly surprised. I used such an array JSONArray and I needed JsonArray . After I spent the replacement everywhere, everything began to work normally, except for adding a file to the array :) I hope this information will be useful to someone.
