Apache Tomcat WebSocket Java message disconnecting client -

i have develop chat application. using websockets. have following code:

public class server {      public static void main(string[] args) {          org.glassfish.tyrus.server.server server = new org.glassfish.tyrus.server.server("localhost", 8025, "/ws", serverendpoint.class);          try {             server.start();             system.out.println("press key stop server..");             new scanner(system.in).nextline();         } catch (deploymentexception e) {             throw new runtimeexception(e);         } {             server.stop();         }     } } 

and serverendpoint is:

package mechanism.chat;  import static java.lang.string.format;  import java.io.ioexception; import java.net.inetsocketaddress; import java.net.unknownhostexception; import java.util.arraylist; import java.util.list;  import javax.websocket.encodeexception; import javax.websocket.onclose; import javax.websocket.onmessage; import javax.websocket.onopen; import javax.websocket.session; import javax.websocket.server.pathparam;  import exception.businessexception; import services.chatgameservices;  @javax.websocket.server.serverendpoint(value = "/chat", encoders = messageencoder.class, decoders = messagedecoder.class) public class serverendpoint {     private chatgameservices chatgameservices;      static list<room> roomlist = new arraylist<room>();        @onopen     public void onopen(session session) {         system.out.println(format("%s joined chat room.", session.getid())); //        peers.add(session);     }      @onmessage     public void onmessage(message message, session session) throws ioexception, encodeexception {         string user = (string) session.getuserproperties().get("user");         this.chatgameservices = new chatgameservices();         int gameid = message.getgameid();         int userid = message.getuserid();         string type = message.gettype();          boolean hasroom = false;         for(room room : roomlist){             if(gameid == room.gameid){                 room.peers.add(session);                 hasroom = true;             }         }         if(!hasroom){             room room = new room();             room.gameid = gameid;             room.peers.add(session);             roomlist.add(room);             system.out.println("" + message.gettype());         }           if (user == null) {             session.getuserproperties().put("user", message.getsender());         } //        if ("quit".equalsignorecase(message.getcontent())) { //          system.out.println("quit"); //            session.close(); //        }          system.out.println(format("[%s:%s] %s", session.getid(), message.getreceived(), message.getcontent()));           //broadcast message         if(message.gettype().equals("message")){             for(room room : roomlist){                 if(room.gameid == gameid){                     try {                          this.chatgameservices.createmessage(gameid, userid, message.getcontent());                      } catch (businessexception e) {                         // todo auto-generated catch block                         e.printstacktrace();                     }                      (session peer : room.peers) {                         if (!session.getid().equals(peer.getid())) { // not resend message sender                             peer.getbasicremote().sendobject(message);                         }                     }                 }             }            } else if(message.gettype().equals("disconnect")){             for(room room : roomlist){                 if(room.gameid == gameid){                     (session peer : room.peers) {                         if (session.getid().equals(peer.getid())) { // not resend message sender //                          peer.getbasicremote().sendobject(message);                             peer.close();                             room.peers.remove(peer);                         }                     }                 }             }            }     }      @onclose     public void onclose(session session) throws ioexception, encodeexception {     }  } 

the problem is: if test local in mac works pretty fine! can send , receive messages between 2 clients. when exporting war file apache server, in windows server, doesn't work. clients can connect when 1 of them send message, other disconnected. have no idea why happening. searched lot, couldn't find anything. thank all!
