Yea, it takes about 10 seconds starting from that page, but how
do you know how to find that page starting from java.sun.com?
There are 15,000 potential paths to follow with no roadsigns :-).
For that matter, how do I know I need a jre rather than a jdk
(I've seen both tossed around on web pages about installing
java).
