Cannot install Java Plugin (1.4.0)

I'm having a problem installing the java plugin for Netscape 6.2 on a RedHat box. After searching the java website I found a page that detailed how to install the plugin but it still doesn't work.
(here's the link to the page: Plugin Installation )

I've logged in as root, to ensure all permissions were available. Even after following the directions and getting a "registration was successful" message the plugin is not showing in the "About plugins".

Any help??
BTW: I'm not familar with the 'setenv' command. I guessed at 'set' yet that didn't gain anything. Also the '$' had to be omitted from the path in regxpcom.

Here's the text from the above link:
1. Before you run regxpcom, as described below, first shut down the browser.
2. setenv LD_LIBRARY_PATH <Netscape 6>:$LD_LIBRARY_PATH

If you do not add Netscape to your LD_LIBRARY_PATH you are likely get an error when you run regxpcom. The message will say that Open failed: No such file or directory.
If and only if you are using Netscape 6.x browsers, you will need to use regxpcom provided by Netscape to register the file. In the package installation of J2SDK 1.4.0, copies of this file are located at /usr/j2se/jre/plugin/i386/ns600/ and /usr/j2se/jre/plugin/i386/ns610/ For example:

cd ${NETSCAPE6}/bin

If you use a Netscape 6.0x browser:

regxpcom ${JRE}/plugin/i386/ns600/

If you use a Netscape 6.1x browser:

regxpcom ${JRE}/plugin/i386/ns610/

After running the regxpcom command you should get a message saying that registration was successful for <jre>/plugin/i386/ns610/

If regxpcom does not register the Java Plug-in successfully?i.e., you get a registration-failed message or a core dump?try creating a link to the Java Plug-in file in the Netscape 6 plugins directory.

cd <Netscape 6>/plugins
ln -s <JRE>/plugin/i386/ns610/ .

Be sure to include the period at the end.

first run this ...


to update the search database

then this...

locate netscape/plugins

if all of them are in /usr/lib/netscape/plugins or some globally accessable folder then thats good

if you have more versions of netscape then make sure you know which one's which by running it with the full path

if you have more than one plugins folder for the same version consider removing the user one for now.

then forget about the regxpcom or whatever for now..

locate the correct plugin for your version.


make a link to the proper plugin in the netscape/plugins folder

like this but use your exact paths, not these

ln -s /usr/j2se/jre/plugin/i386/ns610/ /usr/lib/netscape/plugins/

Thanks from me too! I love stumbling upon the answer to a question in the back of my head.

The method described above worked for Mozilla, too.
