Public bug reported:
After installing sun-java5-plugin, Firefox did not detect the Sun java
plugin.
On my system I had previously installed Java using a package that
modified the equivalents. In particular, the old java package I had used
set the following equivalents:
/etc/alternatives/firefox-javaplugin.so ->
/usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so
/etc/alternatives/mozilla-javaplugin.so ->
/usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so
/etc/alternatives/netscape-javaplugin.so ->
/usr/lib/j2sdk1.5-sun/jre/plugin/i386/ns4/libjavaplugin.so
Unfortunately, upon uninstallation, it did not clean up these
equivalents. They were left as "bad" symlinks.
When I installed the sun-java5-plugin package, it did not update the
equivalents. In particular, it left firefox-javaplugin.so and mozilla-
javaplugin.so alone.
As a result, even running "sudo update-alternatives --config firefox-
javaplugin.so", for example did not do anything, since there was no
equivalent installed.
I am guessing that sun-java5-plugin didn't install its equivalent either
because an equivalent was already there, or because the existing
equivalent was effectively a dead symlink (usr/lib/j2sdk1.5 no longer
exists).
The fix was for me to manually remove the equivalents that were causing
the problem and then reinstall sun-java5-plugin:
apt-get remove sun-java5-plugin
update-alternatives --remove-all firefox-javaplugin.so
update-alternatives --remove-all mozilla-javaplugin.so
update-alternatives --remove-all netscape-javaplugin.so
apt-get install sun-java5-plugin
I feel that sun-java5-plugin should have added its equivalents instead
of bombing out and set them to be default.
