CNET: Google begins barring browser plug-ins from Chrome

Applets, whether old-school applets that are deployed with an HTML tag or modern JNLP applets do require the plugin.

Web Start applications (JWS), which are deployed using JNLP but run outside of the browser, do not require the plug-in.  They are usually launched using mime type associations to fire up javaws.  There is one mechanism that can be used to launch Web Start applications automatically using a JS call but that depends on the native Deployment Toolkit plugin, so if Google proceeds with their plans and if Oracle does nothing that would also be affected.

In both JNLP and tag-style applets, and JWS apps the deployment code takes care of downloading the application artifacts (JARs, DLLs, etc), both initially and if they have changed from what is in the Java app cache (e.g. javaws -viewer).
