UDP

I am creating a UDP client program and this is my piece of code where i receive a message. I cant figure out whats wrong because the method hangs until timer is up and it never receives anything. please review this code for any wrongs.



public void receive() throws IOException, ClassNotFoundException{

//file receiving
byte receive_buffer[] = new byte[10000];
DatagramPacket receive_packet = new DatagramPacket(receive_buffer, receive_buffer.length);
receive_packet.setAddress(IP);
receive_packet.setPort(13);
socket.receive(receive_packet);
System.out.print("inside2"); //testing

//converting received bytes info object it was before
Object o = new Object();
ByteArrayInputStream bo = new ByteArrayInputStream(receive_buffer);
ObjectInputStream oo = new ObjectInputStream(bo);
o = oo.readObject();

}
