Cleaning Java cache

[dstonek]

Suppose I change the applet settings, upgrade /lib or whatever that needs to clean the Java cache or removing temporary files.
Is there a way to perform these tasks from the applet itself to avoid instruct and ask all users to perform them by themselves?
Something like grab a cookie containing version info or something to compare and perform cleaning only once.
Thanks

In in fact closing all browser windows to make sure the applet is unloaded should be enough. When JAR are are updated on server-side, lastmodified timestamp is updated so the JRE should download the new JAR files. Cleaning Java cache is just to make 101% sure that you have the correct version.
