GWT - RPC SerializationException with class object

Question

I am currently trying to use the SyncProxy library to test services of my app, in order to do load testing with JMeter. The app works fine, I am running it on localhost.

I already managed to make some calls, but only when the parameters where

this is the error :

Type 'net.gicm.ector.shared.beans.Utilisateur' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized.

Here is the piece of code where I make the call :

 final Utilisateur user = new Utilisateur();
 user.setUser("C2984");

 TableauDeBordServiceAsync tableauDeBordServiceAsync = (TableauDeBordServiceAsync) SyncProxy
          .newProxyInstance(TableauDeBordServiceAsync.class, MODULE_BASE_URL, GET_SERVICE_NAME_2);
 tableauDeBordServiceAsync.ongletRealisationListeControle(plan, user, codeSI, numStructure, synthese, colonneAtrier, ordre, numeroPagination, filtre, new AsyncCallback<List<List<String>>>() {

    @Override
    public void onFailure(Throwable caught) {
        // TODO Auto-generated method stub
        System.out.println(caught);

    }

    @Override
    public void onSuccess(List<List<String>> result) {
        // TODO Auto-generated method stub
        System.out.println(result);

    }

 });

I looked at this thread, and tried to find where could I do something wrong : https://stackoverflow.com/a/9534704/4628136

My class implements the Serializable interface, has a default empty constructor, and is in the client package.

public class Utilisateur implements Serializable {
   ...
   public Utilisateur() {
   }
   ...
}

But actually, I don't see anything about that Utilisateur class in the gwt.rpc files.

You can get that error also if `Utilisateur` aggregates types which are not Serializable/have no-arg constructor. — Andrei, May 30 '17 at 16:53
Well, there is only one and it does have a no-arg constructor and it implements the Serializable interface — krakig, May 31 '17 at 09:35

I think you need to implement

com.google.gwt.user.client.rpc.IsSerializable

Your class would be like:

public class Utilisateur implements IsSerializable, Serializable {
   ...
   public Utilisateur() {
   }
   ...
}

I still have the same error, even when implementing the `IsSerializable` interface – krakig May 31 '17 at 11:27
Try to put `private static final long serialVersionUID = 1L;` in your `Utilisateur`class – miguialberto May 31 '17 at 12:01
Has your class `Utilisateur` intern class references? I mean, something like `private MyClass myClass;`? All internal references must be also serializable – miguialberto May 31 '17 at 12:11
Nope, it hasn't – krakig May 31 '17 at 12:15
Can you please post the complete `Utilisateur`class? – miguialberto May 31 '17 at 12:23
What happens with classes `Habilitation`, `Structure` and `InfoUserOsireBean`? are all of them serializable and part of `shared`package? – miguialberto May 31 '17 at 12:31
yes, they both are serializable, and are part of the shared package – krakig May 31 '17 at 12:38
If all your classes implements `IsSerializable, Serializable`, my last suggestion is to be sure you have removed all cache from your browser...otherwise I've no idea :( – miguialberto May 31 '17 at 14:44
Actually, this is the scenario : Everything works in the browser (the application itself works), but when I try to simulate a user from my JUnit, this is where I get the problem... – krakig May 31 '17 at 14:48

Make sure all the attributes of this class are also serialized.
