| Method Summary | |
| public void | afterBegin()
The afterBegin method notifies a session Bean instance that a new
transaction has started, and that the subsequent business methods on the
instance will be invoked in the context of the transaction. | | public void | afterCompletion(boolean committed)
The afterCompletion method notifies a session Bean instance that a
transaction commit protocol has completed, and tells the instance whether
the transaction has been committed or rolled back. | | public void | beforeCompletion()
The beforeCompletion method notifies a session Bean instance that a
transaction is about to be committed. | | public void | buy(int s)
Business method implementation. | | public void | ejbActivate()
The activate method is called when the instance is activated from its
"passive" state. | | public void | ejbCreate(String user)
There must be one ejbCreate() method per create() method on the Home
interface, and with the same signature. | | public void | ejbPassivate()
The passivate method is called before the instance enters the "passive"
state. | | public void | ejbRemove()
A container invokes this method before it ends the life of the session
object. | | public int | read()
Business method implementation. | | public void | setSessionContext(SessionContext sessionContext)
Set the associated session context. |
| afterBegin | | public void afterBegin() throws EJBException, java.rmi.RemoteException(Code) | | The afterBegin method notifies a session Bean instance that a new
transaction has started, and that the subsequent business methods on the
instance will be invoked in the context of the transaction. The instance
can use this method, for example, to read data from a database and cache
the data in the instance fields. This method executes in the proper
transaction context.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
java.rmi.RemoteException - - This exception is defined in themethod signature to provide backward compatibility for enterprisebeans written for the EJB 1.0 specification. Enterprise beanswritten for the EJB 1.1 and higher specifications should throwthe javax.ejb.EJBException instead of this exception. Enterprisebeans written for the EJB 2.0 and higher specifications must notthrow the java.rmi.RemoteException. |
| afterCompletion | | public void afterCompletion(boolean committed) throws EJBException, java.rmi.RemoteException(Code) | | The afterCompletion method notifies a session Bean instance that a
transaction commit protocol has completed, and tells the instance whether
the transaction has been committed or rolled back. This method executes
with no transaction context.
Parameters:
committed - - True if the transaction has been committed, false ifis has been rolled back.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
java.rmi.RemoteException - - This exception is defined in themethod signature to provide backward compatibility for enterprisebeans written for the EJB 1.0 specification. Enterprise beanswritten for the EJB 1.1 and higher specifications should throwthe javax.ejb.EJBException instead of this exception. Enterprisebeans written for the EJB 2.0 and higher specifications must notthrow the java.rmi.RemoteException. |
| beforeCompletion | | public void beforeCompletion() throws EJBException, java.rmi.RemoteException(Code) | | The beforeCompletion method notifies a session Bean instance that a
transaction is about to be committed. The instance can use this method,
for example, to write any cached data to a database. This method executes
in the proper transaction context. Note: The instance may still
cause the container to rollback the transaction by invoking the
setRollbackOnly() method on the instance context, or by throwing an
exception.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
java.rmi.RemoteException - - This exception is defined in themethod signature to provide backward compatibility for enterprisebeans written for the EJB 1.0 specification. Enterprise beanswritten for the EJB 1.1 and higher specifications should throwthe javax.ejb.EJBException instead of this exception. Enterprisebeans written for the EJB 2.0 and higher specifications must notthrow the java.rmi.RemoteException. |
| buy | | public void buy(int s)(Code) | | Business method implementation.
Parameters:
s - nb of shares to be bought |
| ejbActivate | | public void ejbActivate() throws EJBException, java.rmi.RemoteException(Code) | | The activate method is called when the instance is activated from its
"passive" state. The instance should acquire any resource that it has
released earlier in the ejbPassivate() method. This method is called with
no transaction context.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
java.rmi.RemoteException - This exception is defined in the methodsignature to provide backward compatibility for enterprise beanswritten for the EJB 1.0 specification. Enterprise beans writtenfor the EJB 1.1 specification should throw thejavax.ejb.EJBException instead of this exception. Enterprisebeans written for the EJB2.0 and higher specifications must throwthe javax.ejb.EJBException instead of this exception. |
| ejbCreate | | public void ejbCreate(String user)(Code) | | There must be one ejbCreate() method per create() method on the Home
interface, and with the same signature.
Parameters:
user - the user name |
| ejbPassivate | | public void ejbPassivate() throws EJBException, java.rmi.RemoteException(Code) | | The passivate method is called before the instance enters the "passive"
state. The instance should release any resources that it can re-acquire
later in the ejbActivate() method. After the passivate method completes,
the instance must be in a state that allows the container to use the Java
Serialization protocol to externalize and store away the instance's
state. This method is called with no transaction context.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
java.rmi.RemoteException - This exception is defined in the methodsignature to provide backward compatibility for enterprise beanswritten for the EJB 1.0 specification. Enterprise beans writtenfor the EJB 1.1 specification should throw thejavax.ejb.EJBException instead of this exception. Enterprisebeans written for the EJB2.0 and higher specifications must throwthe javax.ejb.EJBException instead of this exception. |
| ejbRemove | | public void ejbRemove() throws EJBException, java.rmi.RemoteException(Code) | | A container invokes this method before it ends the life of the session
object. This happens as a result of a client's invoking a remove
operation, or when a container decides to terminate the session object
after a timeout. This method is called with no transaction context.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
java.rmi.RemoteException - This exception is defined in the methodsignature to provide backward compatibility for enterprise beanswritten for the EJB 1.0 specification. Enterprise beans writtenfor the EJB 1.1 specification should throw thejavax.ejb.EJBException instead of this exception. Enterprisebeans written for the EJB2.0 and higher specifications must throwthe javax.ejb.EJBException instead of this exception. |
| read | | public int read()(Code) | | Business method implementation.
the nb of shares bought |
| setSessionContext | | public void setSessionContext(SessionContext sessionContext) throws EJBException, java.rmi.RemoteException(Code) | | Set the associated session context. The container calls this method after
the instance creation. The enterprise Bean instance should store the
reference to the context object in an instance variable. This method is
called with no transaction context.
Parameters:
sessionContext - A SessionContext interface for the instance.
throws:
EJBException - Thrown by the method to indicate a failure caused bya system-level error.
throws:
java.rmi.RemoteException - This exception is defined in the methodsignature to provide backward compatibility for applicationswritten for the EJB 1.0 specification. Enterprise beans writtenfor the EJB 1.1 specification should throw thejavax.ejb.EJBException instead of this exception. Enterprisebeans written for the EJB2.0 and higher specifications must throwthe javax.ejb.EJBException instead of this exception. |
