Package javax.ejb
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.
See: Description
Interface Summary Interface Description
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 is a common superinterface for the SessionBean, EntityBean and MessageDrivenBean interfaces.
EntityBean
The EntityBean interface is implemented by every entity bean class.
EntityContext
The EntityContext interface provides an instance with access to the container-provided runtime context of an entity 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 defines methods that the EJB container uses to notify a message driven bean instance of the instance's life cycle events.
MessageDrivenContext
The MessageDrivenContext interface provides access to the runtime message-driven context that the container provides for a message-driven bean instance.
SessionBean
The SessionBean interface defines methods that the EJB container uses to notify a session bean instance of the instance's life cycle events.
SessionContext
The SessionContext interface provides access to the runtime session context that the container provides for a session bean instance.
SessionSynchronization
The SessionSynchronization interface allows a stateful session bean instance to be notified by its container of transaction boundaries.
TimedObject
The TimedObject interface contains a 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 allows the bean provider to obtain a serializable timer handle that may be persisted.
TimerService
The TimerService interface provides enterprise bean components with access to the container-provided Timer Service.
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.
