Query regarding Me ssageDriven Bean

[Ravi Kiran Va]

Hi ,

I am newbie to MessageDrivenBeans .


Hi i have seen two examples of MDB .
The First One

@MessageDriven(activationConfig =
{
@ActivationConfigProperty(propertyName="destinationType", propertyValue="javax.jms.Queue"),

@ActivationConfigProperty(propertyName="destination", propertyValue="queue/mdb")
})

@MessageDriven(ejbName="CalculatorBean",destinationType="javax.jms.queue",destinationJndiName="queue/mdb")

Please tell me what is the correct way ?? And what is ejbName Attribute and what should be the value passed to it .
