java - ObjectInputStream$BlockDataInputStream.peekByte when using program on internet -

-

i created application tcp, works nice when used on local network 127.0.0.1 server refused works when client try connect him network.

i don't know error means , how resolve , can't anderstand application works on lan.

public class reception {  inputstream inobjet = null; bufferedreader instring = null; objectinputstream recvec2i = null;  public reception(socket socket) {     try {         this.inobjet = socket.getinputstream();         this.instring = new bufferedreader(new inputstreamreader(socket.getinputstream()));         this.recvec2i = new objectinputstream(inobjet);     } catch (ioexception ex) {         logger.getlogger(reception.class.getname()).log(level.severe, null, ex);     } }  public vecteur2i recevoir() {     vecteur2i = new vecteur2i();     try {          = (vecteur2i) recvec2i.readobject();      } catch (ioexception | classnotfoundexception ex) {         logger.getlogger(reception.class.getname()).log(level.severe, null, ex);         = new vecteur2i(1000, 1000);     }     return to; }  public string recevoirstring() {     string chaine = "";     try {         chaine = instring.readline();     } catch (ioexception ex) {         logger.getlogger(reception.class.getname()).log(level.severe, null, ex);     }     return chaine; }  public void fermerreception() {     try {         instring.close();     } catch (ioexception ex) {         logger.getlogger(reception.class.getname()).log(level.severe, null, ex);     }     try {         inobjet.close();     } catch (ioexception ex) {         logger.getlogger(emission.class.getname()).log(level.severe, null, ex);     }     try {         recvec2i.close();     } catch (ioexception ex) {         logger.getlogger(reception.class.getname()).log(level.severe, null, ex);     } } }

and here exception :

avr. 22, 2015 9:33:33 pm snake.reception recevoir grave: null java.io.eofexception @ java.io.objectinputstream$blockdatainputstream.peekbyte(objectinputstream.java:2597) @ java.io.objectinputstream.readobject0(objectinputstream.java:1316) @ java.io.objectinputstream.readobject(objectinputstream.java:370) @ snake.reception.recevoir(reception.java:41) @ snake.partie.cycledejeu(partie.java:55)

regards,

you can't mix different types of stream via same socket when 1 or more of them buffered, , both bufferedinputstream , objectinputstream buffered. buffers 'steal' data each other. in case should i/o via object stream. has string-based methods.
