All the above classes are Pojo's and all the fields of these classes are Serializable I have tried all possible solutions given in java - GWT - RPC SerializationException - Stack Overflow <https://stackoverflow.com/questions/9534484/gwt-rpc-serializationexception/9534704#9534704> I have defined my service as below public interface INamedComboListDataProvider<M> extends RemoteService { public List<M> load(String name); } I also have checked my *serializationWhitelist *and it only contain following 25 classes {class com.google.gwt.user.client.ui.TreeListenerCollection=true, class java.lang.String=true, class com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException=true, class com.google.gwt.user.client.ui.FocusListenerCollection=true, class com.google.gwt.user.client.rpc.RpcTokenException=true, class java.util.LinkedList=true, class java.lang.RuntimeException=false, class com.google.gwt.user.client.ui.LoadListenerCollection=true, class com.google.gwt.user.client.ui.ClickListenerCollection=true, class com.google.gwt.user.client.ui.FormHandlerCollection=true, class java.lang.Throwable=false, class com.google.gwt.user.client.ui.KeyboardListenerCollection=true, class com.google.gwt.user.client.ui.MouseListenerCollection=true, class com.google.gwt.user.client.ui.TabListenerCollection=true, class java.util.Vector=true, class com.google.gwt.user.client.ui.ChangeListenerCollection=true, class com.google.gwt.user.client.ui.ScrollListenerCollection=true, class com.google.gwt.user.client.ui.PopupListenerCollection=true, class com.google.gwt.user.client.ui.MouseWheelListenerCollection=true, class java.util.Arrays$ArrayList=true, class java.lang.Exception=false, class java.util.ArrayList=true, class java.util.Collections$EmptyList=true, class java.util.Collections$SingletonList=true, class com.google.gwt.user.client.ui.TableListenerCollection=true} I also have added project folder structure in attachment. Can anybody guide me where I am going wrong and why does the serializationwhilteList does not contain the pojo models ? -- You received this message because you are subscribed to the Google Groups "GWT Users" group.
