I have did it with the Putty and it conencts well but when i do an robot=new Serial(this,"COM3",9600);
Processing says that it is connected but the led on the bluetooth continue blinking and it doesn't work on processing

i use linux and i want to connect my Processing program with the bluetooth connected to my arduino uno.

i have used this program to Arduino and it works with a mobile phone:

1. byte dada;
   
   
   void setup(){
     pinMode(13,OUTPUT);
     Serial.begin(9600);
     delay(50);
     Serial.println("Conectado");
   }
   
   void loop() {
     if(Serial.available()){
       dada = Serial.read();
       switch(dada){
         case '0':
           digitalWrite(13,LOW);
           delay(500);
           Serial.println("Led off");
           break;
         case '1':
           digitalWrite(13,HIGH);
           delay(500);
           Serial.println("Led on");
           break;
         default:
           delay(500);
           Serial.print(dada);
           Serial.println(" no es una orden valida. Introduzca 0 o 1");
       }
     }
   }

the problem is that i can't connect it from my Processing program. i know that i have it connected to "/dev/rfcomm0" but i have putted this on the program: "robot = new Serial(this,Serial.list()[0],9600);" and this: robot = new Serial(this,"/dev/rfcomm0",9600); and it doesn't work

PD.: it work's well with the cable connected to arduino instead of the bluetooth

When i try to compile a very simple code it shows the following message:

i have installed Processing on my linux but i don't find the libraries that come with the installation. they are not in the folder of Processing
