14:01:41.864 [ERROR] [architecturegwt] Unable to load module entry point class com.structis.smartgwt.client.ArchitectureSmartGWT (see associated exception for details)

This is the message I get using eclipse ans a simple basic application from the tutorial

package com.structis.smartgwt.client;


import com.structis.smartgwt.client.GreetingService;
import com.structis.smartgwt.client.GreetingServiceAsync;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.smartgwt.client.types.Alignment;
import com.smartgwt.client.widgets.Canvas;
import com.smartgwt.client.widgets.Label;
import com.smartgwt.client.widgets.layout.HStack;
import com.smartgwt.client.widgets.layout.VStack;


public class ArchitectureGWT implements EntryPoint {

private static final String SERVER_ERROR = "An error occurred while "
+ "attempting to contact the server. Please check your network "
+ "connection and try again.";

/**
* Create a remote service proxy to talk to the server-side Greeting service.
*/
private final GreetingServiceAsync greetingService = GWT
.create(GreetingService.class);


public void onModuleLoad() {

Canvas canvas = new Canvas();

VStack vStack = new VStack();
vStack.setShowEdges(true);
vStack.setWidth(150);
vStack.setMembersMargin(5);
vStack.setLayoutMargin(10);
vStack.addMember(new BlueBox(null, 40, "height 40"));
vStack.addMember(new BlueBox(null, 80, "height 80"));
vStack.addMember(new BlueBox(null, 160, "height 160"));
canvas.addChild(vStack);

Did anybody had this problem an how to fix it ?
