There's Java HowTos on the CentOS Wiki


I use Sun's JDK, so the following may or may not work in OpenJDK.

The JAVA_HOME here is Sun's JDK:

   ln -s $JAVA_HOME/jre/lib/i386/libnpjp2.so

You'll probably have to create the plugin directory under firefox -
and your version of firefox may be different.

On my machine, I linked

   /usr/lib/firefox-3.0.10/plugins  -> /usr/lib/mozilla/plugins

then linked the Java library to /usr/lib/mozilla/plugins.

Restart your browser and you should see


as the Java plugin.

      Enjoy global warming while it lasts.
