Connexion réinitialisée par un homologue: erreur d'écriture de socket pendant ftp

Question

Lors de la tentative de ftp (avec implicitement ssl) un fichier vers un serveur, je reçois systématiquement un message 'Connection Reset By Peer: Erreur d'écriture de socket' ou anormalement une 'Connection Aborted By Software ' Erreur. Le fichier est téléchargé sur le serveur, mais est complètement vide. Cependant, après avoir configuré un serveur ftp de test local, je télécharge des fichiers sur ce serveur sans problème. Ces erreurs peuvent-elles être causées par un type de pare-feu? Sinon, y a-t-il un autre problème? Si c'est le cas, peut-on changer quelque chose dans le code pour le réparer?

utilisant Apache Commons:

String SFTPHOST = compParam.getSftpHostNme(); 
int SFTPPORT = 990; 
String SFTPUSER = compParam.getSftpLogin(); 
String SFTPPASS = compParam.getSftpPassword(); 
      FTPSClient ftpClient = new FTPSClient(true); 
    try { 

     ftpClient.connect(SFTPHOST, SFTPPORT); 
     if(!ftpClient.login(SFTPUSER, SFTPPASS)){ 
      SwingUtils.showMessage(this, "Error: Trouble Connecting \n" + "User Name and Password or Host is incorrect \n" 
        + "or someone else is using these credentials"); 
      return; 
     } 
     ftpClient.enterLocalPassiveMode(); 
     ftpClient.setFileType(FTP.ASCII_FILE_TYPE); 

     File f = new File(TLCTripRecordExportDlg.filePath + TLCTripRecordExportDlg.fileName); 

     String remoteFile = TLCTripRecordExportDlg.fileName; 
    FileInputStream inputStream = new FileInputStream(f); 
    ProgressMonitorInputStream pmiStream = new ProgressMonitorInputStream(this,"Uploading the File",inputStream); 
//  OutputStream os = ftpClient.storeFileStream(remoteFile); 
//  byte[] buffer = new byte[1024]; 
//  int len; 
//  while ((len = pmiStream.read(buffer)) != -1) 
//  { 
//   os.write(buffer, 0, len); 
//   os.flush(); 
//  } 
//  pmiStream.close(); 
//  os.close(); 


    if(ftpClient.storeFile(remoteFile, pmiStream)){ 
    inputStream.close(); 
    pmiStream.close(); 
    }else{ 

    SwingUtils.showMessage(this, "File Not Uploaded: " + ftpClient.getReplyString()); 
    return; 
    } 

L'erreur est renvoyée au fichier magasin. Voici la trace de la pile:

J'ai trouvé la réponse. Ajoutez ces deux lignes:

 ftpClient.execPROT("P"); 
     ftpClient.execPBSZ(0);
