java on mozzilla

[david smethurst]

hi all
have downloaded and installed:

UnZipSFX 5.40 of 28 November 1998, by Info-ZIP ([e-mail]).
  inflating: j2re-1_4_2_04-linux-i586.rpm
Done.
[root@localhost mozzie]# rpm -iv j2re-1_4_2_04-linux-i586.rpm
Preparing packages for installation...
j2re-1.4.2_04-fcs
[root@localhost mozzie]# exit

now i need to create the link to where
or perhaps, better put, how and to where

java is at:

/usr/java/j2re1.4.2_04/plugin/i386

with three sub-folders:

ns4 - ns610 - ns610-gcc32;

not sure which one to put the link to but i have only done this once
before and have forgotten what commands are needed to create the link

thanks for any help
david
