How can I write to a remote file using Apache Comm

Question

Once the program is connected to the server using the FTPClient connect() method, how can I send Strings and append them to a file located in the remote machine?

I have read other posts but they don't use Apache Commons Net library.

From the docs (you did check the docs, right?), you need the appendFile() method on the FTP client.

Something like

String text = "...."
String remoteFileName = "..."
FTPClient ftp = ... // Already connected

try (ByteArrayInputStream local = new ByteArrayInputStream(text.toBytes("UTF-8"))) {
    ftp.appendFile(remoteFilename, local);
} catch (IOException ex) {
    throw new RuntimeException("Uh-oh", ex);
}
