ejbCreate

public void ejbCreate()
               throws javax.ejb.CreateException
Create the Session Bean which takes the first available MBeanServer as target server

Throws:
javax.ejb.CreateException

toString

public String toString()
Describes the instance and its content for debugging purpose

Returns:
Debugging information about the instance and its content

setSessionContext

public void setSessionContext(javax.ejb.SessionContext aContext)
                       throws javax.ejb.EJBException
Set the associated session context. The container invokes this method on an instance after the instance has been created.

This method is called with no transaction context.

Specified by:
setSessionContext in interface javax.ejb.SessionBean
Parameters:
aContext - A SessionContext interface for the instance. The instance should store the reference to the context in an instance variable.
Throws:
javax.ejb.EJBException - Should something go wrong while seting the context, an EJBException will be thrown.

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

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
