Subject ActiveMQ (5.7 snapshot) and MQTT: connection times out while still connected to a topic for receiving
Date Tue, 25 Sep 2012 21:49:29 GMT
ActiveMQ (5.7 snapshot) and MQTT: connection times out while still connected
to a topic for receiving

I'm using mosquitto's python client to connect to an mqtt topic. When using
the mosquitto broker,
all works (but that broker doesn't allow me to plug in authentication to my
database, so it's no real option).

When using activemq, the connection is disconnected. The clients does ping,
and the broker does respond. But it doesn't have seem an effect as the
connection still times out.

Am i missing some configuration option?


broker config (scala):
===================================================================
val broker = new BrokerService()
broker.setPlugins(Array(new UpoAuthenticationPlugin(admin_user, admin_pw)))

broker.addConnector("mqtt+nio://127.0.0.1:1883")
broker.addConnector("vm://localhost")
broker.start()
===================================================================

python client:
===================================================================
import mosquitto
import os
import time

client = mosquitto.Mosquitto("test-client")
client.username_pw_set("user", "password")

def on_connect(mosq, obj, rc):
    if rc == 0:
        print("Connected successfully.")

client.on_connect = on_connect

def on_disconnect(mosq, obj, rc):
    print("Disconnected successfully.")

client.on_disconnect = on_disconnect

def on_publish(mosq, obj, mid):
    print("Message "+str(mid)+" published.")

client.on_publish = on_publish

def on_message(mosq, obj, msg):
    print("Message received on topic "+msg.topic+" with QoS "+str(msg.qos)+"
and payload "+msg.payload)

client.on_message = on_message

def on_subscribe(mosq, obj, mid, qos_list):
    print("Subscribe with mid "+str(mid)+" received.")

client.on_subscribe = on_subscribe

client.connect("127.0.0.1", keepalive=5)

client.subscribe("groups/Nameless", 1)
client.publish("groups/Nameless", "hello world", 1)

while True:
    print "loop" , client.loop()
    time.sleep(2)    
    pass
