Java String per RX TX senden

Hi ich habe eine Gui für meine Diplomarbeit geschrieben jetzt muss ich 
den String der durch Textfelder erzeugt wird senden. Ich will per Rs232 
die Daten auf ein anderes Gerät senden. Mein Problem ist, dass es immer 
einen Error beim CommportIdentifier gibt bitte umhilfe.

Quellcode:
