From that same page:

mappedName() : Specifies the product-specific name of the target Remote EJB. In SUN's case, this refers to the global JNDI name of the target Remote EJB.
[b]
Not applicable for local interfaces[/b] because beanName() can always be used

So the mapped name might be getting ignored.
