Java Enterprise in a Nutshell, Second Edition

Name

EJBMetaData

Synopsis

This interface provides meta-data object a particular type of enterprise JavaBean. It allows you to query for the bean type’s home interface, the Class for its home interface, the Class of its primary key (for entity beans only), the Class for its remote interface, and whether the bean is a session bean.

This meta-data might be used by EJB development tools to introspect on additional aspects of EJB classes that can’t be obtained from the Object introspection methods.

Any implementations of this interface are required to be serializable, and must be valid for use over RMI.
