Hello everyone,

My ROS version is jade. I am able to publish message to the drone. However, I cannot subscribe any topics due to the error - Unable to load the manifest for package bebop_msgs.

Java ROS bridge is used in the program. Here is the source of the Java ROS bridge: https://github.com/h2r/java_rosbridge

I followed the instruction to use the Java ROS bridge.

Here is the code of subscribing:

mvROSBridge.subscribe("/bebop/states/common/CommonState/BatteryStateChanged", "bebop_msgs/CommonCommonStateBatteryStateChanged", new RosListenDelegate() {
            @Override
            public void receive(JsonNode data, String stringRep) {
                System.out.println(mvDrone.getName() + " received: " + stringRep);
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        });

Problem: Unable to load the manifest for package bebop_msgs

Please help me, thank you.
