Problem with Software Serial no response

I am using an Arduino Uno baord with IDE 1.6.7. I have tried to implement a tweaked version of the basic example( SoftwareSerial Example) from Software Serial library. The code is attached. It should blink the light and print the message on the serial monitor. But I am not getting anything . In fact , I tried the example as it is also . It did not work either.

#include <SoftwareSerial.h>
SoftwareSerial mySerial(8, 9); // RX, TX
void setup() {
pinMode(13,OUTPUT);
// Open serial communications and wait for port to open:
 Serial.begin(9600);
 while (!Serial) {
  ; // wait for serial port to connect. Needed for native USB port only
 }


Serial.println("Goodnight moon!");

// set the data rate for the SoftwareSerial port
  mySerial.begin(9600);
delay(1000);
}

void loop() { // run over and over
mySerial.println("hell");

if(mySerial.available()>0) {
  
  
   digitalWrite(13,HIGH);
   Serial.write("working..");
   delay(3000);
   digitalWrite(13,LOW);
   delay(2000);
  }


}
