Not sure if this is appropriate forum..but I thought I would start here.
We have applet based web application, and we are experiencing situations when the Client machine's java browser plugin cache is not cleared and hence the latest application updates are not reflected on the client PC, unless they manaully go and clean the java Cache (Control panel --> Java). I was wondering if there is a way to access and remove these cache programatically using java?
- I would rather be coding !

Don't quote me on this, but I'd assume not, as the access it requires goes beyond what is allowed to prevent hacking.
You can try specifying a no-cache option for the applet. There is no guarantee every browser will honor the policy however, and for those that due will make loading time for each page load the same (given no cache, the browser downloads the applet every time). There may also be a way to version the applet (for webstart there is), if the browser detects a new version it will not use the cached version, so I encourage you to search the net to investigate this
Actually, its not just the Applet, but all these dependent jar files that needs to get downloaded before the app starts on the client machine. The applet itself is a 3rd party applet that lets you specify the jar file we need to download onto the client machine in their configuration file, for the app to run.
I was reading a little bit and I understand the security concerns, but I was wondering if we can Sign the jar files, and would that allow us to bypass these security issues? And this is a intranet application and we cannot expect every user to manually clean up the cahce on their local machine which is not pretty..there got to be a way around..isn't it?
