To install java plugin
Java Runtime Environment
Version: 1.4.2_05 or later
1. Install Java Runtime Environment.
2. Make a symbolic link to libjavaplugin_oji.so in your Mozilla Plugins directory. Unless you are using an old version of Mozilla, or one you compiled yourself with gcc 2.9x, use the copy located in the plugin/i386/ns7 directory of JRE 5.0, or plugin/i386/ns610-gcc32 if you are using JRE 1.4.2.
# cd /usr/lib/firefox-3.0.5/plugins # ln -s /opt/java/jre/plugin/i386/ns7/libjavaplugin_oji.so ./libjavaplugin_oji.so
Do not copy the plugin to your plugs directory. If you do, Mozilla will crash any time you attempt to view a page containing a Java applet.
