Hei,

After I updated my java version from 6u31 to 7u4 on a windows 7-64 bits, applets stopped working. I use java-32 bits and the browsers are also 32 bits(tried IE9 and Firefox 12.0) , and the only cause was updating the java.
I used the test from http://www.java.com/en/download/testjava.jsp, and got this as result:

security: Reset deny session certificate store

I already tried a lot of different alternatives like disabling the firewall, disabling the next generation plug-in on Java Control Panel, clearing the cache, uninstalling and re-installing (both JRE and JDK), playing with mixed mode security verification, and maybe some more I don’t remember.
I have no idea what else I could try to make it work.. Anyone experienced the same and solved it?

Ah, as company policy we have to stick with the latest version if possible due to security updates.

    Ok, the problem was that I was connected on VPN (CISCO) while accessing pages with java. Since Java 7, there is a problem due to Ipv6 (http://jonathangiles.net/blog/?p=1126). So I disabled it from the VPN connection and added this line to the java runtime parameters:
    -Djava.net.preferIPv4Stack=true

    Now it’s working fine.
