Re: [jetty-dev] How to enable extended listener types for a servlet cont

Thanks Jan, indeed precisely as you pointed you. Just for the sake of reference and documentation, it is not necessary to include Spring's ContextLoaderListener in such setup as everything is wired and initialized through Java configuration.

Behrooz,

You're trying to add a context listener too late in the webapp's
lifecycle: you're already into initializing servlets.

If you want to programmatically add this listener, do it before you
start the webapp.
