I am trying, without success, to run:
http://media.pearsoncmg.com/aw/aw_kurose_network_2/applets/dns/dns.html
The problem is the applet.  The Java I have on  my Lenny system is too old.
Hardly surprising.  So I switched to Wheezy.  Still not OK.  I checked: I
only had openjdk-6-jre.  So I installed openjdk-7-jre and its dependencies.
Still no joy.  I imagine that iceweasel is not using it at all, or not in the
way that jre 7 needs.  What can I do to run this applet?  This is a course in
OSS, so it shouldn't require anything proprietary.
Thanks
