Question

I have a method that returns a list of serializable objects, I make an RPC call to this method and everything went well until the deserialization process: I received the following message: “The response could not be deserialized”

Note: Here is my gwt-rpc response string:

 / / OK [0,2768,3,2,0,2764,3,2,0,2761,3,2,0,2754,3,2,0,2750 , 3,2,0,2610,3,2,0,2606,3,2,0,2603,3,2,0,2600,3,2,9,1 ["java.util.ArrayList/3821976829 "" myPackage.MyEntity/845101117 "," java.lang.Integer/3438268394 "], 0.7]

DTO

public class MyEntity implements Serializable,IsSerializable
{
   private static final long serialVersionUID = -9032157988566853424L;

   public MyEntity ()
   {
      super();
   }

   private Integer _entityId; 


   private String _name;

   public Integer getEntityId()
   {
      return _entityId;
   }

   public void setEntityId(Integer entityId)
   {
      this._entityId = entityId;
   }

   public String getName()
   {
      return _name;
   }

   public void setName(String _name)
   {
      this._name = _name;
   }

}

Interfaces

@RemoteServiceRelativePath("ContributorService.rpc")
public interface ContributorService extends RemoteService
{
   ArrayList<MyEntity> myMethod(Arg arg);
}

---

public interface ContributorServiceAsync
    {

       void myMethod(Arg arg, AsyncCallback<ArrayList<MyEntity>> callback);

    }

Server Implementation:

@SuppressWarnings("serial")
public class ContributorServiceImpl extends RemoteServiceServlet implements ContributorService
{

   @Override
   public ArrayList<MyEntity> myMethod(Arg arg)
   {
      ArrayList<MyEntity> myList = new ArrayList<MyEntity>();
MyEntity myEntity=new MyEntity();
      //code...
myList .add(myEntity);
      return myList;
   }
}

Thanks for your help

Thank you to everyone for the help
it was a stupid mistake that I still can not understand.
I changed GWT sdk and the program worked, then I used the old SDK to ensure that the problem emanates from the sdk but the surprise the program still works ‘:(

I understand nothing of what is past but the more important that my application works 🙂
