Re: How to add MIME types - dynamically -

[Maxence Dewil <th...@gmail.com>]

For posterity:

1. Implement a Feature (or easier, extend AbstractFeature).
2. In the initialize(Bus) method, get the FactoryBeanListenerManager instance through bus.getExtension(FactoryBeanListenerManager.class).
3. Implement a FactoryBeanListener and register it through FactoryBeanListenerManager.addListener(FactoryBeanListener).
4. The FactoryBeanListener intercepts the Event.START_CREATE event, and from there you can manipulate the REST resource metadatas (i.e. JAXRSServiceFactoryBean.getClassResourceInfo() -> ClassResourceInfo.getMethodDispatcher().getOperationResourceInfos()).
