The "name" attribute is jndiname within the java:comp/env namespace of the component into which the bean is being injected. So if you have:

  | @Stateless
  | public AnotherBean...
  | {
  | 
  |  @EJB(name="someName")
  |  private BeanOne bean;
  | ..
  | }
This means that the BeanOne is available at java:comp/env/someName jndiname of the AnotherBean's java:comp/env namespace.

The mappedName is actually the global jndiname (not the java:comp/env namespace) of the bean. The mappedName is actually not portable. Each vendor (application server) can implement this the way they want and are even allowed to ignore it.

I found this useful http://java.sun.com/products/ejb/javadoc-3_0-fr/javax/ejb/EJB.html
