How to bind a label to text in backing class?

How can I bind a GWT label to a string property in the backing class for the view?

Login.ui.xml:
Welcome <g:Label text="{textFromJavaBackingClass}" />

class Login {
  String userName;
  String getUserName() { return userName; }
}

How can I bind the value to String userName?

Declare class in xml

   <ui:with field="myclass" type='package.ClassName' />

In Ui binder write 

g:Label text='{myclass.getUsername}'></g:Label>

Here is the reference for future

Let's say you have a i18n class MyI18n which extends Messages

Just include the following

<ui:with field="i18n" type="MyI18n"/>

Then 

Welcome <g:Label text="{i18n.textFromJavaBackingClass}" />

Note : MyI18n is actually not required to extends Messages, this is just the common way to call any no-arg method.

<ui:with field="clazz" type="AnyClass"/>

Welcome <g:Label text="{clazz.anyMehtodWhichDoesNotTakeArgs}" />
