Package javax.ejb

The javax.ejb package contains the Enterprise JavaBeans classes and interfaces that define the contracts between the enterprise bean and its clients and between the enterprise bean and the EJB container.

接口摘要
EJBContext	The EJBContext interface provides an instance with access to the container-provided runtime context of an enterprise Bean instance.
EJBHome	The EJBHome interface must be extended by all enterprise Beans' remote home interfaces.
EJBLocalHome	The EJBLocalHome interface must be extended by all enterprise Beans' local home interfaces.
EJBLocalObject	The EJBLocalObject interface must be extended by all enterprise Beans' local interfaces.
EJBMetaData	The EJBMetaData interface allows a client to obtain the enterprise Bean's meta-data information.
EJBObject	The EJBObject interface is extended by all enterprise Beans' remote interfaces.
EnterpriseBean	The EnterpriseBean interface must be implemented by every enterprise Bean class.
EntityBean	The EntityBean interface is implemented by every entity enterprise Bean class.
EntityContext	The EntityContext interface provides an instance with access to the container-provided runtime context of an entity enterprise Bean instance.
Handle	The Handle interface is implemented by all EJB object handles.
HomeHandle	The HomeHandle interface is implemented by all home object handles.
MessageDrivenBean	The MessageDrivenBean interface is implemented by every message-driven enterprise Bean class.
MessageDrivenContext	The MessageDrivenContext interface provides access to the runtime message-driven context that the container provides for a message-driven enterprise Bean instance.
SessionBean	The SessionBean interface is implemented by every session enterprise Bean class.
SessionContext	The SessionContext interface provides access to the runtime session context that the container provides for a session enterprise Bean instance.
SessionSynchronization	The SessionSynchronization interface allows a session Bean instance to be notified by its container of transaction boundaries.
TimedObject	The TimedObject interface contains the callback method that is used to deliver timer expiration notifications.
Timer	The Timer interface contains information about a timer that was created through the EJB Timer Service.
TimerHandle	The TimerHandle interface is implemented by all EJB timer handles.
TimerService	The TimerService interface provides enterprise bean components with access to the container-provided Timer Service.

Exception Summary
AccessLocalException	An AccessLocalException is thrown to indicate that the caller does not have permission to call the method.
ConcurrentAccessException	A ConcurrentAccessException indicates that the client has attempted an invocation on a stateful session bean while another invocation is in progress.
CreateException	The CreateException exception must be included in the throws clauses of all create methods defined in an enterprise Bean's home interface.
DuplicateKeyException	The DuplicateKeyException exception is thrown if an entity EJB object cannot be created because an object with the same key already exists.
EJBAccessException	This exception indicates that client access to a business method was denied.
EJBException	The EJBException exception is thrown by an enterprise Bean instance to its container to report that the invoked business method or callback method could not be completed because of an unexpected error (e.g. the instance failed to open a database connection).
EJBTransactionRequiredException	This exception indicates that a request carried a null transaction context, but the target object requires an active transaction.
EJBTransactionRolledbackException	This exception indicates that the transaction associated with processing of the request has been rolled back, or marked to roll back.
FinderException	The FinderException exception must be included in the throws clause of every findMETHOD(...) method of an entity Bean's home interface.
NoSuchEJBException	A NoSuchEJBException is thrown if an attempt is made to invoke a method on an object that no longer exists.
NoSuchEntityException	The NoSuchEntityException exception is thrown by an Entity Bean instance to its container to report that the invoked business method or callback method could not be completed because of the underlying entity was removed from the database.
NoSuchObjectLocalException	A NoSuchObjectLocalException is thrown if an attempt is made to invoke a method on an object that no longer exists.
ObjectNotFoundException	The ObjectNotFoundException exception is thrown by a finder method to indicate that the specified EJB object does not exist.
RemoveException	The RemoveException exception is thrown at an attempt to remove an EJB object when the enterprise Bean or the container does not allow the EJB object to be removed.
TransactionRequiredLocalException	This exception indicates that a request carried a null transaction context, but the target object requires an active transaction.
TransactionRolledbackLocalException	This exception indicates that the transaction associated with processing of the request has been rolled back, or marked to roll back.

Annotation Types Summary
ActivationConfigProperty
ApplicationException	Applied to an exception to denote that it is an application exception and should be reported to the client directly(i.e., unwrapped).
EJB	Indicates a dependency on the local or remote view of an Enterprise Java Bean.
EJBs	Declares multiple TYPE-level @EJB annotations.
Init	Designates a method of a session bean that corresponds to the create method of an adapted Home interface or an adapted Local Home interface.
Local	When used on the bean class, declares the local business interface(s) for a session bean.
LocalHome	Declares the Local Home or adapted Local Home interface for a session bean.
MessageDriven	Component-defining annotation for a message driven bean.
PostActivate	Designates a method to receive a callback after a stateful session bean has been activated.
PrePassivate	Designates a method to receive a callback before a stateful session bean is passivated.
Remote	Declares the remote business interface(s) for a session bean.
RemoteHome	Declares the Remote Home or adapted Remote Home interface for a session bean.
Remove	Applied to a business method of a stateful session bean class.
Stateful	Component-defining annotation for a stateful session bean.
Stateless	Component-defining annotation for a stateless session bean.
Timeout	Designates a method on a stateless session bean class or message driven bean class that should receive EJB timer expirations for that bean.
TransactionAttribute	When applied at the TYPE-level, designates the default transaction attribute for all business methods of the session or message driven bean.
TransactionManagement	Declares whether a session bean or message driven bean has container managed transactions or bean managed transactions.
