public abstract String mappedName

The product specific name of the EJB component to which this ejb reference should be mapped. This mapped name is often a global JNDI name, but may be a name of any form. Application servers are not required to support any particular form or type of mapped name, nor the ability to use mapped names. The mapped name is product-dependent and often installation-dependent. No use of a mapped name is portable.
