NPE(NullPointerException)

in processing 2.2.1:

import com.temboo.core.*;
import com.temboo.Library.Yahoo.Weather.*;
import processing.serial.*;

Serial port;
int temperature;
// Create a session using your Temboo account application details
TembooSession session = new TembooSession("user", "app", "hash");
void setup() {
  runGetTemperatureChoreo();
  port = new Serial(this, "COM3", 9600); 
}

void runGetTemperatureChoreo() {
  GetTemperature getTemperatureChoreo = new GetTemperature(session);
  getTemperatureChoreo.setAddress("novorossiysk");
  GetTemperatureResultSet getTemperatureResults = getTemperatureChoreo.run();

  temperature=int(getTemperatureResults.getTemperature());
  temperature = (temperature-32)*5/9;
  println(temperature);
  println(Serial.list()[1]);
  if(temperature==27){
    println(port.available());
    while (port.available() == 0) {
       delay(300);
       port.write(65);
}
}
}

After that code i got: 27 (temperature - it`s okay, i convert F to C =) ) And i get error NullPointerException. Arduino is okay, in loop:

if (Serial.available()){ // If data is available to read,
       val = Serial.read();
       Serial.write(val);
}

can not understand that the hell, now over 3 hours of night, i want to sleep.
