Here's an example of how Service Connects to AWS IOT MQTT for RSA topics and process RSADataUpload Request .

}
public static void main(String[] args) {

m.process();
}
/**

*/
public void process() {
mqttClient = new AWSIotMqttClient("endpoint", clientId, "awsAccessKeyId", "awsSecretAccessKey");
try {
mqttClient.connect();
iotTopic = new AWSIotTopic("/RSA/#",AWSIotQos.QOS1){
public void onMessage(AWSIotMessage msg) {
try {
UconnectMessage msgIn = UconnectMessage.parseFrom(msg.getPayload(),extRegistry);
GlobalUconnectExtRoadSideAssist.RSADataUpload rsaDataMsg = msgIn.getMessages(0).getExtension(GlobalUconnectExtRoadSideAssist.rsaDataUpload);
//Receive Car data for RoadSide Assistance.
} catch( Exception ex) {
ex.printStackTrace();
}
}
};
mqttClient.subscribe(iotTopic);
} catch (AWSIotException e) {
System.out.println("Caught Exception "+e);
e.printStackTrace();
}
}
}
The example code demonstrates how to connect with AWS IoT for publishing and subscribing to the RSA topic.
