Warum kann ich nicht bekommen diese Karte über das Senden von SMS über GSM in Java initialisieren

Question

Erstens, ich habe so ein Problem hier zuerst habe ich eine NullPointerException beim Versuch, eine Verbindung mit COM-Port 12, habe ich versucht, diese mehrere verschiedene Wege, indem Sie zuerst den Port auswählen und ihn danach suchen, indem Sie nach dem Port suchen und ihn ausprobieren. Das zweite Mal hielt ich diese 32-Bit-64-Bit-Mismatch-Ausnahme für meine RXTX lib immer so fixierte ich und kam dann mit diesem Fehler auf

So, nach diesem Fehler ich mein Modem-Modus (Huawei e3531) überprüft, dass Ich habe es benutzt und es von WCDMA in den GSM-Modus geschaltet. Was sollte ich jetzt tun? Hier ist mein Code: Das ist meine Klasse Connect

package sendMessage;

     CommPortOwnershipListener

    static String comPort = ""; // This COM Port must be connect with GSM Modem or your mobile phone 
    private CommPortIdentifier portId = null; 
    private Enumeration<?> portList;

    public Connect(String comm) 
    { 

     Connect.comPort = comm; 
    } 

    public boolean init() 
    { 
     portList = CommPortIdentifier.getPortIdentifiers(); 
     while (portList.hasMoreElements()) 
     { 
      portId = (CommPortIdentifier) portList.nextElement(); 
      System.out.println(portId); 
      if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) 
      { 
       if (portId.getName().equals(comPort)) 
       { 
        return true; 
       } 
      } 
     } 
     return false; 
    }

    } 


    public void send(String cmd)

     } 
     catch (IOException e) 
     {

     } 
    } 

    public void sendMessage(String phoneNumber, String message) 
    { 
     send("AT+CMGF=1\r"); 
     send("AT+CMGS=\"" + phoneNumber + "\"\r\n"); 
     send(message + '\032'); 
    } 


    public void connect() throws NullPointerException, PortInUseException 
    {

      try

       serialPort = (SerialPort) portId.open("MobileGateWay", 2000); 
      } 
      catch (PortInUseException e) 
      { 
       e.printStackTrace(); 
      } 

      try 
      { 
       inputStream = serialPort.getInputStream(); 
       outputStream = serialPort.getOutputStream();

    }

ich diese Frage vor gefragt, aber keine Antworten zu bekommen scheinen, jeder Vorschlag ist?

Danke!

Answer 1

Schließlich löste ich mein Problem, Ich habe gerade 32-Bit-JDK anstelle von 64-Bit-JDK und Fehler verschwunden, vielen Dank für Kommentare
