Here are some quick instructions for a particular demo. You can put the 
/usr/Jdev/usr/sbin into your path to save typing all that. 

	1. log into d0sgi0 and set your display to your node
	2. cd ~lueking/java/unlimited/UNAL2I6J
	3. /usr/Jdev/usr/sbin/jdev&
	4. In the "Program" field type "traffic.html" <cr>
	5. push the "run" button and watch the traffic

But that's just a cute demo, there are some more demos which I have been 
playing with from the "java in a nutshell" examples. They are in 
~lueking/java/javanut/examples/*/*. For example, in section5 there is an 
example called AllEvents.java. To run it  cd to ~lueking/java/javanut/examples/
section5 and  say "java AllEvents&". Or to use the development kit say "jdev 
AllEvents.class" . Let me know if you have trouble.
