redis - ERR only (P)SUBSCRIBE / (P)UNSUBSCRIBE / PING / QUIT allowed in this context -

i using jdish.publish in web app , jedis.subscribe in desktop app. both separate app.

i have pubsub class

public class redisnewpostlistener extends jedispubsub {      private final jedis jedis;     private final appinstances appinstances;      public redisnewpostlistener(appinstances instances, jedis jedis) {         this.jedis = jedis;         appinstances = instances;     }      @override     public void onmessage(string channel, string message) {         string[] pos = message.split("##");         double lat = double.parsedouble(pos[0]);         double lon = double.parsedouble(pos[1]);          list<georadiusresponse> members = jedis.georadius("usersbylocation", lon, lat, geo_search_range, geounit.km); 

i calling like

redisnewpostlistener postlistener = new redisnewpostlistener(instances, jedis); jedis.subscribe(postlistener, "newpostarrived");
