- - messageListenerInterface
```
public abstract java.lang.Class messageListenerInterface
```
    Message-listener interface. If the message-driven bean class implements more than one interface other than java.io.Serializable, java.io.Externalizable, or any of the interfaces defined by the jakarta.ejb package, the message listener interface must be specified.
    
    Returns:
    
    a Class object.

- - mappedName
```
public abstract java.lang.String mappedName
```
    A product specific name(e.g. global JNDI name of a queue) that this message-driven bean should be mapped to. 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.
