How do I update Java Plug-in for my browser after I have upgraded to a new version of Java Runtime Environment?
This article applies to:
- Platform(s):
Sun Java Desktop System, Red Hat Linux, SUSE Linux
- Browser(s):
Netscape 6.2x, Netscape 7, Mozilla 1.4+
- JRE version(s):
1.5.0
During the Java Runtime Environment (JRE) installation process, a symbolic link to the Java Plug-in in the browser’s directory is necessary to enable Java Plug-in for your browser. If you are upgrading to a new version of the JRE, then the Java Plug-in for the old JRE will stay effect until you update the symbolic link. Follow these steps to update the link:
- Remove the old symbolic link
- Create new symbolic link
Remove the old symbolic link
- Open new Terminal window
- Go to the plugins sub-directory under the Mozilla installation directory
cd <Mozilla installation directory>/plugins
- In the current directory, remove a symbolic link to the JRE ns7/libjavaplugin_oji.so file. Type:
rm libjavaplugin_oji.so
Example:
- If Mozilla is installed in this directory:
/usr/lib/mozilla-1.4/
- if the JRE is installed at this directory:
/usr/java/jre1.5.0
- and if the symbolic link name is libjavaplugin_oji.so
- Then type at the terminal to go to the browser plug-in directory:
cd /usr/lib/mozilla-1.4/plugins
- Enter the following command to remove a symbolic link to the Java Plug-in for the Mozilla browser.
rm libjavaplugin_oji.so
Create new symbolic link
- Open new Terminal window
- Go to the plugins sub-directory under the Mozilla installation directory
cd <Mozilla installation directory>/plugins
- In the current directory, create a symbolic link to the JRE ns7/libjavaplugin_oji.so file. Type:
ln -s <JRE installation directory>/plugin/i386/ns7/libjavaplugin_oji.so
Example:
- If Mozilla is installed in this directory:
/usr/lib/mozilla-1.4/
- and if the new JRE is installed at this directory:
/usr/java/jre1.5.0_04
- Then type at the terminal to go to the browser plug-in directory:
cd /usr/lib/mozilla-1.4/plugins
- Enter the following command to create a symbolic link to the Java Plug-in for the Mozilla browser.
ln -s /usr/java/jre1.5.0_04/plugin/i386/ns7
/libjavaplugin_oji.so .
- Start Mozilla browser or restart it if it is already running. Note that if you have other Mozilla components (ie: Messenger, Composer, etc) running, you will need to restart them as well.
- Go to Edit > Preferences. Under Advanced category > Select Enable Java
