Is Java WebStart Deprecated?

[Michael Nascimento]

Hi Donald,

I've heard this argument before and it seems Oracle is not aware of
why enterprises use Java WebStart. It has *nothing* to do with a
central JRE, but actually with distributing and upgrading applications
automatically without using installers and requiring admin privileges,
especially in Windows environments. That's at least what I see here in
Brazil in several companies I've consulted for and what people tell me
after desktop-related talks.

Saying this could be replaced with a jlink generated image or an
installer is really ignoring how this is really dealt with by the Java
community and even why Java was a good pick for those desktop
applications - a WORA that doesn't require an installer with admin
rights and auto-upgrade with a differential download protocol is the
key factor for choosing JWS. And I see no replacement being provided
by the JDK or even in the roadmap.

Using the ‘jlink’ tool introduced with JDK 9 will make it even easier for application developers to package and deploy dedicated runtimes rather than relying on a pre-installed system JRE.  Oracle will begin transitioning from the standalone architecture later next year in what will be a multi-year effort.
