java - Server is not connecting -

-

i have void method called startserverconnection() connects server port, in case 7777. method called inside action listener button in class, clientgui.

i'm pretty sure code correct, reason output "waiting connection..."

    public void startserverconnection(){         try{             serversocket = new serversocket(portnumber);              while(true){                 system.out.println("waiting connection...");                 socket clientsocket = serversocket.accept();                 system.out.println("connection established on port: "+clientsocket.getlocalport());                 clientconnection clientconnection = new clientconnection(clientsocket);                 thread thread = new thread(clientconnection);                 thread.start();             }            }         catch(exception e){             e.printstacktrace();             return;         }     }

edit client class, connectclient method:

    public void connectclient(string user){         try{             host = clientsocket.getinetaddress();             clientsocket = new socket(host,port);             new clienthandler(clientsocket).run();             string accepted = "connection host "+host+" accepted on port: "+clientsocket.getport();         }         catch(exception e){             //sendmessage("connection error: "+e);             //servergui.appendeventslog("client "+new clientgui(username, port)+" failed connect");         }      }

any ideas on what's wrong?

update:

public void connectclient(string user){     try{         clientsocket = new socket(host,port);         // use printwriter send data out server         // use bufferedreader receive data server     }     catch(exception e){         //sendmessage("connection error: "+e);         //servergui.appendeventslog("client "+new clientgui(username, port)+" failed connect");     } }

host ip address or hostname, if server/client running on same machine, can either use "127.0.0.1" or "localhost"; port value of int, in case 7777

original:

accept() blocking function. code afterwards not go thorough until connection established.

you have build client side , request connection, once server , client connected, see "connection established on port.."

public socket accept() throws ioexception

listens connection made socket , accepts it. method blocks until connection made.
