2. Uninstall any previous installations ofJava Plugin.
Only one Java Plugin can be used at a time. When you want to use a different plugin,or version of a plugin, remove the symbolic links to any other versions andcreate a fresh symbolic link to the new one.
3. Create a symbolic link to the libnpjp2.so file in the browserplugins directory

cd<Firefox installation directory>/plugins
· Create the symbolic link
ln -s<Java installation directory>/lib/i386/libnpjp2.so

Note: If you are upgrading your Java version then before creating newsymbolic link you should remove old symbolic link to enable latest downloadedJava.
To remove old symbolic link:
type cd<Firefox installation directory>/plugins
rmlibjavaplugin_oji.so
Example
· If Firefox is installed at thisdirectory:
/usr/lib/<Firefoxinstallation directory>
· And if the Java is installed at thisdirectory:
/usr/java/<Javainstallation directory>
· Then type in the terminal window to goto the browser plug-in directory:
/usr/lib/<Firefoxinstallation directory>/plugin
· Enter the following command to create asymbolic link to the Java Plug-in for the Mozilla browser.
ln -s/usr/java/<Java installation directory>/lib/i386/libnpjp2.so
