[SOLVED] java applets won't load.

alan99 · 03-19-2010, 02:12 PM

I'm using Iceweasel on Debian, and my java applets won't work. They used to work fine so I don't understand what happened to them. I installed the latest java jre from Sun and it made no difference. Java plugin seems to work (at least the javascript part) but it can't seem to download applet's. I tried running one locally (ran on of the example applet that came with the Sun jdk, but they won't work on the web) the java console pops up with these errors.

Problem solved. It had something to do with ipv6. I enabled packet forwarding for ipv6 in sysctl.conf and it now works.
