Vaadin on Glasfish

I am trying to setup GlassFish Tools Bundle For Eclipse V 1.2
Eclipse 3.5.1
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Vaadin 6.2.3
Windows 7

I have the following application

public class E1interopApplication extends Application {
@Override
public void init() {
Window mainWindow = new Window("E1interop Application");
Label label = new Label("Hello Vaadin user");
mainWindow.addComponent(label);
setMainWindow(mainWindow);
}

}

But I am getting the following error in the log file and the webpage shows up as blank. Does anyone know how to fix this?

Thank You

including gwt-user.jar did the trick.

yup, inluding this library solves the issue, thanks Henri for workaround for the time until glassfish 3.1
