Enabling jre 1.3 with Java 2 support in Mozilla 1.2

I keep getting the error it needs this plug in, which I have a link set up in /opt/mozilla/plugins. It is: /opt/java/jre1.3.1_07/plugin/i386/ns4/libjavaplugin_oji.so The site is http://www.hgtv.com/hgtv/pac_ctnt/text/0,,HGTV_3936_5500,FF.html (My wife is sure we are going to win it!) I have even tried linking it from the ns600/ directory, but it doesn't work either. Same with copying it directly into the /plugins directory. It is set up exactly like this for Netscape 7, (using the ns600 plugin) and it works fine. It also works fine in Konqueror, just not in Mozilla. What am I missing, besides damaged brain cells? Harry G
