* The EJBMetaData interface allows a client to obtain the enterprise bean's meta-data information.

*
*
* Note that the EJBMetaData is not a remote interface. The class that implements this interface (this class is
* typically generated by container tools) must be serializable, and must be a valid RMI/IDL value type.
