Answer 1

You can read from remote and write to remote using jcifs-1.3.15.jar jar in java but first you need to share location from remote system then it's possible.

try{
            String strLine="";    
            NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("WORKGROUP", "username", "passwd"); // Authentication info here, domain can be null
    //        try (InputStream is = new SmbFile("smb://DESKTOP-0xxxx/usr/local/cache/abc.txt", auth).getInputStream()) {
            try (InputStream is = new SmbFile("smb://xx.xx.xx.xxx/dina_share/abc.txt", auth).getInputStream()) {
                BufferedReader br = new BufferedReader(new InputStreamReader(is));
            while ((strLine = br.readLine()) != null) {
                System.out.println(strLine);
            }
            } catch (IOException e) {
                e.printStackTrace();
            }
            String smbURL="smb://xx.xx.xx.xxx/dina_share/abcOther.txt";
            SmbFileOutputStream fos = new SmbFileOutputStream(new SmbFile(smbURL,auth));
            byte bytes[]="Wellcome to you".getBytes();
            fos.write(bytes);
        }catch(Exception e){
            e.printStackTrace();
        }
