Message Driven Bean Selectors (JMS)

问题

I have recently discovered message selectors

@ActivationConfigProperty(
        propertyName="messageSelector",
        propertyValue="Fragile IS TRUE")

My Question is: How can I make the selector dynamic at runtime?

Lets say a consumer decided they wanted only messages with the property "Fragile IS FALSE"

Could the consumer change the selector somehow without redeploying the MDB?

Note: I am using Glassfish v2.1

To my knowledge, this is not possible. There may be implementations that will allow it via some custom server hooks, but it would be implementation dependent. For one, it requires a change to the deployment descriptor, which is not read after the EAR is deployed.
