Below is the code i am trying

String deviceId = "mqqdirectdevice1";     
          String brokerUri = "ssl://xxxxx:8883";
          String clientId = deviceId;
          System.out.println( "Connecting to " + brokerUri +" as "+clientId);

          MqttAsyncClient client = null;
          try {

              client = new MqttAsyncClient( brokerUri, clientId,new MemoryPersistence());
              
            if ( client != null ) {             
              MqttConnectOptions options = new MqttConnectOptions();                          
              client.setCallback( new AzureCallback() );             
              options.setUserName("xxxxxx.net/mqqdirectdevice1?api-version=2018-06-30");
              options.setPassword(sasToken.toCharArray());
             // options.setPassword(sasToken.toCharArray());
              options.setKeepAliveInterval(230);
              options.setCleanSession(false);
              options.setMqttVersion(4);              
              IMqttToken token=client.connect( options );
              token.waitForCompletion(60 * 1000);
              System.out.println("Sent MQTT CONNECT packet was acknowledged");
              if ( client.isConnected() ) {

            e.printStackTrace();
          } finally {
