Welcome, I have a problem with "GWTENT" reflection.
How to create a class using reflection?
I tried this:

try {
ClassType ct = TypeOracle.Instance.getClassType(Klient.class);
ct.invoke(null, "Klient", null);
} catch (ReflectionRequiredException e) {
// TODO Auto-generated catch block
call the class:

package pl.cba.lukaszbaczek.client.Test;

import com.extjs.gxt.ui.client.widget.Window;
import com.google.gwt.user.client.Element;
import com.gwtent.reflection.client.Reflectable;
import com.gwtent.reflection.client.Reflection;

public class Klient extends Window implements Reflection {

protected void onRender(Element parent, int index) {
super.onRender(parent, index);
setSize(600, 600);

public Klient(){

But fails with the error:
17:30:59.129 [ERROR] [makerbase] Uncaught exception escaped
com.gwtent.reflection.client.NotFoundException: Klient not found or unimplement?
