Frustrated with GWT Binder

Hi all,

I'd like to create a UI like the sample application Mail. But I meet
some weird problems.

When I run the application, I can only see an empty page with nothing,
What's wrong with my code ?


The following is my sample code:

// widget binder xml

<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui"
xmlns:e="urn:import:zjffdu.tutorial.gwt.uibinder.client">
<ui:style>
.bolder {
font-weight: bolder;
}
</ui:style>
<g:DockLayoutPanel unit="EM">
<g:center size="40">
<g:Label text="my label"></g:Label>
</g:center>
</g:DockLayoutPanel>

</ui:UiBinder>

// binder java class

public class MyBinderWidget extends Composite {

private static MyBinderWidgetUiBinder uiBinder = GWT
.create(MyBinderWidgetUiBinder.class);

interface MyBinderWidgetUiBinder extends UiBinder<Widget,
MyBinderWidget> {
}

public MyBinderWidget() {
initWidget(uiBinder.createAndBindUi(this));


}

}

/**
* Entry point classes define <code>onModuleLoad()</code>.
*/
public class UIBinderExample implements EntryPoint {

/**
* This is the entry point method.
*/
public void onModuleLoad() {
MyBinderWidget widget=new MyBinderWidget();
RootPanel.get().add(widget);
}
}
