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

Question

I am using jdish.publish in my web app and jedis.subscribe in my desktop app. so both are separate app.

I have this 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 am calling it like

RedisNewPostListener postListener = new RedisNewPostListener(instances, jedis);
jedis.subscribe(postListener, "NewPostArrived");

I am getting this error:

redis.clients.jedis.exceptions.JedisDataException: ERR only (P)SUBSCRIBE / (P)UNSUBSCRIBE / PING / QUIT allowed in this context

Answer 1

It seems that you use the same jedis client for subscribe and publish. You just need to create another client and one is for subscribe and the other is for publish
