public  void ejbActivate() throws EJBException, RemoteException
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.

 public  void ejbPassivate() throws EJBException, RemoteException
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.

 public  void ejbRemove() throws EJBException, RemoteException
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.

 public  void setSessionContext(SessionContext ctx) throws EJBException, RemoteException
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.
