Arron:

You need to use the Plug-in in order to run the latest
JRE from Java Software in your Netscape browser.

See

http://java.sun.com/products/plugin/

for more information about the Plug-in, and

http://java.sun.com/security/signExample12/
for an example that uses signed applets with the Plug-in.
