Interface javax.ejb.SessionBean
- public interface interface SessionBean
- extends EnterpriseBean
The SessionBean interface is implemented by every session enterprise bean
class. The container uses the SessionBean methods to notify the enterprise
bean instances of the instance's life cycle events.
-
ejbActivate()
- The activate method is called when the instance is activated
from its "passive" state.
-
ejbDestroy()
- A container invokes this method before it ends the life of the session
object.
-
ejbPassivate()
- The passivate method is called before the instance enters
the "passive" state.
-
setSessionContext(SessionContext)
- Set the associated session context.
setSessionContext
public abstract void setSessionContext(SessionContext ctx) throws EJBException
- 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 in no transaction context.
- Parameters:
- ctx - An SessionContext interface for the instance.
- Throws: EJBException
- Thrown if the instance could not perform the
function requested by the container.
ejbDestroy
public abstract void ejbDestroy() throws EJBException
- 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 destroy
operation, or when a container decides to terminate the session object
after a timeout.
This method is called in no transaction context.
- Throws: EJBException
- Thrown if the instance could not perform the
function requested by the container.
ejbActivate
public abstract void ejbActivate() throws EJBException
- 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 in no transaction context.
- Throws: EJBException
- Thrown if the instance could not perform the
function requested by the container.
ejbPassivate
public abstract void ejbPassivate() throws EJBException
- The passivate method is called before the instance enters
the "passive" state. The instance should release any resources that
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 in no transaction context.
- Throws: EJBException
- Thrown if the instance could not perform the
function requested by the container.
