I'm making a large Java game applet. I have a large .JAR
How large? 1 Meg? 5 Meg? 50 Meg?
Currently 1.2MB, but that's classes only, without any of my multimedia
and levels, which should push it up to something (hopefully) <15MB.
I hope your users have wide 'bands'.. I would grimace at
the thought of dowbloading 15 Meg. of IDE or plug-in,
let alone (something as trivial as) a game..
...I really want to display it in-browser instead of using JWS.
Why? Why (as an end user) would I need a bunch of irrelevant
browser buttons surrounding the game-play area?
The "JarURLConnection" class looks promising, especially since the
ancestor provides a "setUseCaches" hint.
(IE - menus) Tools | Internet Options (button) Clear History
Any cached resources (where the browser actually listened
to the setUseCaches attribute in the first place) will be gone.
...Has anyone used this successfully in an applet?
The thing you really need to understand with applets,
is that even if you can get something a little different
working in an applet in a browser in one version of
the VM, will not necessarily work as you planned it
to in the next browser/browser version or VM.
It is enough trouble to get a 1.1 applet reliably on-screen
in a whole bunch of browsers, without bringing browser
caching behaviour (over which Java/JVM has little or no
control) into the equation.
..I see some references to security exceptions
on questions posted on the Internet.
Yes. That is when an applet tries something that is
restricted and is not signed/trusted by the user.
The ideas I mentioned earlier in regard to actively
taking control of caching, would require a trusted
applet/application.
