EJBMetaData (Java EE 5 SDK)

javax.ejb Interface EJBMetaData

public interface EJBMetaData

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

The meta-data is intended for development tools used for building applications that use deployed enterprise Beans, and for clients using a scripting language to access the enterprise Bean.

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.
