I need to save the newly created DomSource object as new xml file into a folder inside the SFTP Server (not transfering a file from local computer into SFTP).

Here is the code

public void save(String xmlFilePath, Document document) {

        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        transformerFactory.setAttribute(XMLConstants.ACCESS_EXTERNAL_DTD, "");
        transformerFactory.setAttribute(XMLConstants.ACCESS_EXTERNAL_STYLESHEET, "");
        Transformer transformer;
        try {
            transformer = transformerFactory.newTransformer();
            DOMSource domSource = new DOMSource(document);
            StreamResult streamResult = new StreamResult(new File(xmlFilePath));
            transformer.transform(domSource,streamResult);

        } catch (TransformerException | NullPointerException e) {
            e.printStackTrace();
        }
    }

Use JSch SSH/SFTP library.

1. Afaik, it's the lost widely used SFTP library for Java

2. It supports uploading data from streams.

   I assume that its ChannelSftp.put overload that returns OutputStream can be hooked to your StreamResult (instead of the File).

   StreamResult streamResult =
       new StreamResult(channelSftp.put("/sftp/path/file.zml"));
