Subject Re: SSL Connection to MQTT
Date Fri, 05 Aug 2016 14:18:53 GMT

There’s a general MqttSample that should also work w/SSL configs here https://github.com/apache/incubator-quarks/blob/master/samples/connectors/src/main/java/org/apache/edgent/samples/connectors/mqtt/README

If the mqtt server uses a CA-signed certificate, then all you should have to do is specify
use of the ssl://… MQTT server URL.

For a non-CA-signed cert, you’ll have to manually add the server’s cert to a trust store
and set the MqttConfig’s “trustStore” and “trustStorePassword” items for it.

There's an SSL config test for MqttStreams here that nets out to the above:  https://github.com/apache/incubator-quarks/blob/master/connectors/mqtt/src/test/java/org/apache/edgent/test/connectors/mqtt/MqttStreamsTestManual.java#L1155

Hope that helps.
