Hi there,
well, i figured what the problem is. I decided, when I moved to 7.0 , to enable IPV6 in my kernel. I don't actually have it set up properly, but i hope i'll be able to play with it soon.
. Since then, all my java apps that relied on networking stopped working. I fixed most of them by adding to my environment:
JAVAVM_OPTS_javaws=-J-Djava.net.preferIPv4Stack=true
JAVAVM_OPTS_java=-Djava.net.preferIPv4Stack=true
Under Eclipse, I have to run/debug applications passing -Djava.net.preferIPv4Stack=true to their environment.
The fix for applets is very similar : in the java control panel, Java tab, 'Java applet Runtime Settings', set the Java Runtime parameters to "-Djava.net.preferIPv4Stack=true". and voila! everything working again.
Hope this helps someone.
best,
B
