It's really frustrating. since the error tells: "Type '*java.lang.Boolean*'
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.: instance = true"
When i try to make the following generic rpc call
@RemoteServiceRelativePath("testService")
public interface TestService extends RemoteService {
public <T extends Response<V>, V extends Serializable, D extends
Serializable> T execute(
Action<T, V, D> action);
}
here is the implementation:
@SuppressWarnings("serial")
public class TestServiceImpl extends RemoteServiceServlet implements
TestService {
@SuppressWarnings("unchecked")
@Override
public <T extends Response<V>, V extends Serializable, D extends
Serializable> T execute(
Action<T, V, D> action) {
System.out.println("action.data: " + action.toString());
DefaultResponse<Boolean> result = new DefaultResponse<Boolean>();
result.value = Boolean.TRUE;
return (T) result;
}
}
Thanks
