Java plugin Firefox 3.6.8 Ubuntu 9.10 will not load

more options

I'm running KUbuntu 9.10.

Have manually installed Firefox 3.6.8 in /opt/firefox

Have followed online tutorials covering Java manual installation:

http://www.java.com/en/download/help/linux_install.xml

Java is located in /usr/local/jre1.6.0_21/plugin/i386/ns7/libjavaplugin_oji.so

Have created a symlink as advised in tutorials, both methods:

lrwxrwxrwx 1 username username 64 2010-08-26 12:07 /opt/firefox/plugins/libjavaplugin_oji.so -> /home/username/jre1.6.0_21/plugin/i386/ns7/libjavaplugin_oji.so

lrwxrwxrwx 1 username username 59 2010-08-26 12:17 /home/username/.mozilla/plugins/libjavaplugin_oji.so -> /usr/local/jre1.6.0_21/plugin/i386/ns7/libjavaplugin_oji.so

Java still does not load. No error or complaint, just as if it were never there. Does not show up in about:plugins.

libjavaplugin_oji.so is not the correct Java plugin for Firefox 3.6.

See http://kb.mozillazine.org/Java


In Firefox 3.6 and later versions you need the Next-Generation Java™ Plug-In present in Java 6 U10 and later (Linux: libnpjp2.so; Windows: npjp2.dll).
