Proper SuperDevMode launching

General
1

Hello,

I almost managed to get it working but a tiny bit is still left I suppose. I followed the book instructions, with this package structure:

{context}.widgetset
    /client
        AppEntryPoint.java
    /public
        kinetic-v4.7.3-dev.js
    kinetic.gwt.xml
    NewPikaterWidgetset.gwt.xml

  1. AppEntryPoint.java:
package org.newpikater.appserver.vaadin.gui.widgetset.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.RootPanel;

public class AppEntryPoint implements EntryPoint
{
    @Override
    public void onModuleLoad()
    {
        Window.alert("Wow, it works!");
        RootPanel.get().add(new Label("Wow, it works!"));
        // ClientVars.setPreviewBrowserEvents(); // adds a keyboard listener that keeps track of what keys are currently pressed
    }
}

WHAT HAPPENS:
When I run the SuperDevMode launch with NewPikaterWidgetset as the target widgetset, start Tomcat and paste the application URL in my browser, I can see the dialog message “It’s working” (as declared in “AppEntryPoint.java”) but nothing else after that. A red rectangle with a waiting cursor appears and that’s where the application “hangs”. Probably some kind of an error…
I would much rather launch with the other module descriptor (“kinetic”) as it seems more logical to me but compilation of the module in SuperDevMode results in an error saying that “AppEntryPoint.java” can not be found, probably because it is not compiled as a standalone widgetset?

So, what am I doing wrong? Do I suspect correctly that I need to seperate these 2 widgetsets into 2 seperate packages? Are there some conventions about this not mentioned in the book (at the very least, I didn’t notice any)? How can I start developing a client-side application and have all the exceptions and errors display in Eclipse console log?
