------------------------------------------------------------

@Resource / resource-ref is what a component would use to inject the JNDI resource.  The component that binds the JNDI resource would not want @Resource ... as that jndi value would not exist and result in the deployment failing to deploy (chicken & the egg problem).  The only workaround I've seen is to do a try / catch in the @PreDestory and log warning if it does not exist.  The workaround would have PreDestroy remove the jndi value if the deployment is undeployed when the app server is still running, and when the app server is shutdown it would either unbind it or the app server would unbind it and a warning would be logged.

It would be good to allow the component that binds it into jndi to attempt to unbind it at shutdown before the app server binds it down.
