Hi list,
I have ffox 2, jdk1.5 and .16 installed and working ok for other programs.
I have the 1.5 plugin loaded and recognised OK in about:plugins:

$ sudo ln -s /usr/local/jdk1.5.0/jre/plugin/i386/ns7/libjavaplugin_oji.so libjavaplugin_oji.so
When I try to load Sun's applet test ( http://www.java.com/en/download/help/testvm.xml ) , but I get this in the java console , and the applet doesn't load :

I tested it with JAVA_HOME unset (my default) and with JAVA_HOME set to /usr/local/jdk.1.5.0/, with JAVA_VERSION set and unset.
When I try another applet, randomly on the web ( http://www.java.com/en/download/help/testvm.xml ) , i get the following too

If i load the 1.6 plugin instead, i get the same result, BUT ffox locks up , using over 60% CPU non stop. FFox stops refreshing its window , and I have to kill it.
The environment is the same on 6.2 (eg, no lib paths defined,etc), but never had this problem... Any pointers?
( I reiterate, Eclipse, freemind, yed, Lucene's Luke analyzer, and others work just fine)
thanks,
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
