Like my applet would detect java version and if that's too low, it would
quit. But there is no way to quit.
No there isn't. That is not how an applet should behave.
An applet is a 'guest' in the user's browser. It might
share a JVM with other applets in the same page,
other frames in the same browser window, or other
browser windows/tabs.
It does not make sense to assume it should
'shut down' *any* VM. That idea is relfected
in that, any attempt to do so (even in a signed
applet) will fail.
Note that:
1) Web-start can launch the applet and ensure
the correct minimum version.*
2) The only mehtods might be open for applets are..
- the complex nested <object>/<embed> form
of the applet element that can do versioning.
- use showDocument to flip the page to a
"upgrade Java" page.
- use a similar applet to ensure minimum Java
is installed *before* showing the applet page.
* In this day and age, a web-start launched
applet will work much better than any applet
in a browser.
