java - Kryonet connection successful but not receiving messages -


hi using kryonet network library game i'm developing.

i've got code in server side:

public class myserver {     kryo kryo;     server server;     connection connection;     public myserver(){         server = new server();         server.start();         try {             server.bind(59990, 59900);         } catch (ioexception e) {             system.out.println("fatal error");         }          kryo = server.getkryo();         kryo.register(message.class);          server.addlistener(new listener() {             public void received (connection con, message str) {                 system.out.println("message recieved client server");                 message m = (message)str;                 system.out.println(m.text);              }             public void connected(connection con){                 system.out.println("hey, connected!");                 connection = con;                 con.sendtcp("hola cliente!!");             }             public void disconnected(connection con){                 system.out.println(":( gone... he'll never come back..");             }         });      }      public void sendmessage(string tipomensaje,string tipotropa,string id){         connection.sendtcp(tipomensaje+"-"+tipotropa+"-"+id);     }  }

and in client side:

public class myclient {     client client;     connection connection;     kryo kryo;     public myclient(){         client = new client();         client.start();           try {             kryo = client.getkryo();             kryo.register(message.class);              client.connect(5000, "10.211.55.3", 59990, 59900);             //sendmessage("fromclient","ee","ee");              client.addlistener(new listener() {                 public void received (connection con, string str) {                       system.out.println(str);                        system.out.println("message recieved server client");                 }                 public void connected(connection con){                     system.out.println("hey, connected!");                     connection = con;                     message m = new message();                     m.text="eeep";                     client.sendtcp(m);                 }                 public void disconnected(connection con){                     system.out.println(":( gone... he'll never come back..");                 }             });           } catch (ioexception e) {             system.out.println("error while connecting");         }          }       public void sendmessage(string tipomensaje,string tipotropa,string id){         client.sendtcp(tipomensaje+"-"+tipotropa+"-"+id);         system.out.println("message sent client server");      } }

message class string in it. when try connect client server "hey, connected!" message , afterwards "message recieved client server" in server's command line. however, m.text (the content of message) not printed , don't know why.

thanks in advance.

it's because there no method public void received (connection con, string str) in listener - basically, server never calls it. reason why should use @override - wouldn't have problem in first place.

replace string str object o. - check if object message. if is, cast message , print out text. method should this:

@override public void received(connection connection, object packet) {     if (packet instanceof message) {         system.out.println(((message) packet).text);     } }
