Class Summary

Class	Description
AsyncResult<V>	Wraps the result of an asynchronous method call as a Future object, preserving compatability with the business interface signature.
ScheduleExpression	A calendar-based timeout expression for an enterprise bean timer.
TimerConfig	TimerConfig is used to specify additional timer configuration settings during timer creation.

Enum Summary

Enum	Description
ConcurrencyManagementType	Used to specify the value of the ConcurrencyManagement annotation for a singleton session bean.
LockType	Concurrency lock type for singleton beans with container-managed concurrency.
TransactionAttributeType	The enum TransactionAttributeType is used with the TransactionAttribute annotation to specify whether the methods of a session bean or message driven bean are called with a valid transaction context.
TransactionManagementType	The enum TransactionManagementType is used with the TransactionManagement annotation to specify whether container-managed or bean-managed transaction management is used.

Exception Summary

Exception	Description
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 or singleton bean while another invocation is in progress and such concurrent access is not allowed.
ConcurrentAccessTimeoutException	This exception indicates that an attempt to concurrently access a stateful session or singleton bean method resulted in a timeout.
CreateException	The CreateException exception must be included in the throws clauses of all create methods defined in an enterprise bean's home or local home interface.
DuplicateKeyException	The DuplicateKeyException exception is thrown if an entity EJB object or EJB local 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 is thrown to report that the invoked business method or callback method could not be completed because of an unexpected error (e.g.
EJBTransactionRequiredException	This exception indicates that a request carried a null transaction context, but the target object requires an active transaction.
EJBTransactionRolledbackException	This exception is thrown to a remote client to indicate 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 finder method of an entity bean's home or local home interface.
IllegalLoopbackException	This exception indicates that an attempt was made to perform an illegal loopback invocation.
NoMoreTimeoutsException	This exception indicates that a calendar-based timer will not result in any more timeouts.
NoSuchEJBException	A NoSuchEJBException is thrown if an attempt is made to invoke a business method on a stateful session or singleton 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 a local object (local EJB object or timer) that no longer exists.
ObjectNotFoundException	The ObjectNotFoundException exception is thrown by a finder or select method to indicate that the specified EJB object or local object does not exist.
RemoveException	The RemoveException is thrown at an attempt to remove an EJB object or local EJB object when the enterprise bean or the container does not allow the EJB object to be removed.
TransactionRequiredLocalException	This exception is thrown to a local client to indicate that a request carried a null transaction context, but the target object requires an active transaction.
TransactionRolledbackLocalException	This exception is thrown to a local client to indicate that the transaction associated with processing of the request has been rolled back, or marked to roll back.

Annotation Types Summary

Annotation Type	Description
AccessTimeout	Specifies the amount of time in a given time unit that a concurrent access attempt should block before timing out.
ActivationConfigProperty	Used to provide information to the deployer about the configuration of a message driven bean in its operational environment.
AfterBegin	Designate a stateful session bean method to receive the after begin session synchronization callback.
AfterCompletion	Designate a stateful session bean method to receive the after completion session synchronization callback.
ApplicationException	Applied to an exception to denote that it is an application exception and should be reported to the client directly (i.e., unwrapped).
Asynchronous	Used to mark a session bean method as an asynchronous method or to designate all business methods of a session bean class as asynchronous.
BeforeCompletion	Designate a stateful session bean method to receive the before completion session synchronization callback.
ConcurrencyManagement	Declares a singleton session bean's concurrency management type.
DependsOn	Used to express an initialization dependency between singleton components.
EJB	Indicates a dependency on the local, no-interface, or remote view of an Enterprise JavaBean.
EJBs	Declares multiple EJB annotations.
Init	Designates a method of a session bean that corresponds to a create<METHOD> method of an adapted home or local home interface (an interface that adapts an EJB 2.1 or earlier EJBHome or EJBLocalHome client view respectively).
Local	Declares the local business interface(s) for a session bean.
LocalBean	Designates that a session bean exposes a no-interface view.
LocalHome	Declares the local home or adapted local home interface for a session bean.
Lock	Declares a concurrency lock for a singleton session bean with container managed concurrency.
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 interface or adapted remote home interface for a session bean.
Remove	Applied to a business method of a stateful session bean class to indicate to the container that the stateful session bean is to be removed by the container after completion of the method.
Schedule	Schedule a timer for automatic creation with a timeout schedule based on a cron-like time expression.
Schedules	Applied to a timer callback method to schedule multiple calendar-based timers for the method.
Singleton	Component-defining annotation for a singleton session bean.
Startup	Mark a singleton bean for eager initialization during the application startup sequence.
Stateful	Component-defining annotation for a stateful session bean.
StatefulTimeout	Specifies the amount of time a stateful session bean can be idle (not receive any client invocations) before it is eligible for removal by the container.
Stateless	Component-defining annotation for a stateless session bean.
Timeout	Designates a method on a stateless session bean class, a singleton session bean class, a message driven bean class, or an EJB 2.x entity bean class that should receive EJB timer expirations for that bean.
TransactionAttribute	The TransactionAttribute annotation specifies whether the container is to invoke a business method within a transaction context.
TransactionManagement	Specifies whether a session bean or message driven bean has container managed transactions or bean managed transactions.
