Method Detail

setSessionContext

public void setSessionContext(javax.ejb.SessionContext ctx)
                       throws javax.ejb.EJBException

Set the associated session context. The container calls this method after the instance creation. This references is stored in the sessionContext instance variable.

This method is called with no transaction context.

Specified by:

setSessionContext in interface javax.ejb.SessionBean

Parameters:

ctx - - A SessionContext interface for the instance.

Throws:

javax.ejb.EJBException - - Thrown by the method to indicate a failure caused by a system-level error.

ejbRemove

public void ejbRemove()
               throws javax.ejb.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 remove operation, or when a container decides to terminate the session object after a timeout.

This method is called with no transaction context.

Specified by:

ejbRemove in interface javax.ejb.SessionBean

Throws:

javax.ejb.EJBException - - Thrown by the method to indicate a failure caused by a system-level error.

ejbActivate

public void ejbActivate()
                 throws javax.ejb.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 with no transaction context.

Specified by:

ejbActivate in interface javax.ejb.SessionBean

Throws:

javax.ejb.EJBException - - Thrown by the method to indicate a failure caused by a system-level error.

ejbPassivate

public void ejbPassivate()
                  throws javax.ejb.EJBException

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.

Specified by:

ejbPassivate in interface javax.ejb.SessionBean

Throws:

javax.ejb.EJBException - - Thrown by the method to indicate a failure caused by a system-level error.

ejbCreate

public void ejbCreate()
               throws javax.ejb.EJBException

Dummy implementation of a create method.

Throws:

javax.ejb.EJBException
