I am trying to set a object to an stateful EJB which has an array.
If I do this in the Web container in a servlet it works fine but when I try do the same in the remote application I am getting an marshalling error
Let me put the codes
and more details

This is the object I am trying to insert into the Bean's List, this in a module called "core"
public class IoTDeviceReadingState implements Serializable {
int capturedVehicleSpeed = 0;
String capturedTrafficLightStatus = null;
Coordinate capturedGPSCoordinates = null;
This is the Bean interface
@Remote
public interface IoTDeviceReadingStore extends Serializable {
void configureBean();
void setReading(IoTDeviceReadingState reading);
List<IoTDeviceReadingState> getReadings();
}
Bean Implementation
@Stateful
public class IoTDeviceReadingStoreBean implements IoTDeviceReadingStore {
private List<IoTDeviceReadingState> readings = new LinkedList<>();
@PostConstruct
public void configureBean(){
this.readings = new LinkedList<>();
}
public void setReading(IoTDeviceReadingState reading){
this.readings.add(reading);
}
public List<IoTDeviceReadingState> getReadings(){
return readings;
}
}
Testing it in Servlet
IoTDeviceReadingState state = new IoTDeviceReadingState();
String lightStatus = "green";
int speed = 100;
state.captureTrafficLightStatus(lightStatus);
state.captureVehicleSpeed(speed);
IoTDeviceReadingStore readingStoreBean = (IoTDeviceReadingStore) context.lookup("java:global/ear/app/IoTDeviceReadingStoreBean");
readingStoreBean.setReading(state);
No errors worked fine
Trying to do this in another app
IoTDeviceReadingState state = new IoTDeviceReadingState();
String lightStatus = IoTDataGenerator.randomStatus();
int speed = IoTDataGenerator.randomSpeed();
state.captureTrafficLightStatus(lightStatus);
state.captureVehicleSpeed(speed);
IoTDeviceReadingStore readingStoreBean = (IoTDeviceReadingStore) context.lookup("java:global/ear/app/IoTDeviceReadingStoreBean");
readingStoreBean.setReading(state);
The error I am getting is
Exception in thread "main" jakarta.ejb.EJBException: java.rmi.MarshalException: CORBA MARSHAL 1330446347 Maybe; nested exception is:
