Hi Paul,
You can download the latest JRE from
http://java.sun.com/javase/downloads/index.jsp
JRE 6 Update 16
Also, if you don't want to use the browser to launch NMC, you can do this
command line
<JRE Installation>/bin/javaws http://yournmcservername:9000/gconsole.jnlp
Your browser executes this command
The reason why NMC asks for JRE path in the NMC installation is that command
line reporting requires Java.
I do believe NMC protects the passwords for NMC users
