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 _________________________ {Beto|Norberto|Numard} Meijome "At times, to be silent is to lie." Miguel de Unamuno I speak for myself, not my employer.
