Service implementation reloading is the live reloading of Tapestry-IOC service implementation classes without having to stop & restart the servlet container. Available for Tapestry 5.2 and later, it extends the developer productivity gains of Tapestry's Live Class Reloading to your Tapestry-IOC service modules.

Why is this important?

On the one hand, a good application design keeps the page and component classes "thin" and moves logic into the services layer, for easier reuse across pages. On the other hand, moving logic into services would be less agile if those services didn't auto-reload the way Tapestry pages do.

Be careful about publishing any instances of a reloadable class.

In an application that is not driven by the web tier, you will need to periodically invoke the fireCheckForUpdates() method of the UpdateListenerHub service (which was moved from tapestry-core to tapestry-ioc for this purpose).
