Monitoring Port 80

I'm writing a java program to monitor port 80 & retrieve the bytes that pass through that port. For this, i wrote the following code.

Socket sc=new Socket(InetAddress.getLocalHost(),80);

BufferedReader in=new BufferedReader(new InputStreamReader(sc.getInputStream()));

String s="";

while ( (s=br.readLine()) !=null )

{

System.out.println(s);

}

However, when i run the program, it prints out nothing & just exits. What should i do?
