Archived thread 1383737 from Ubuntuzilla. Markdown source: Ubuntuzilla/thread_1383737_SeaMonkey_not_detecting_Java.md
Using the new Ubuntuzilla repo, I installed SeaMonkey 2.0.2. Java is not being detected. Places that use Java uploaders (Facebook and the like) work fine in Firefox. In SeaMonkey I get a gray box telling me to install Java.

Plugins detected by SeaMonkey. Note that there is no Java: [IMG]http://i50.tinypic.com/352lwzc.jpg[/IMG]
Ideas??
.
what's your java plugin package name?
what do you see in /usr/lib/mozilla/plugins (anything java?)
fwiw, i have seamonkey installed from the ubuntuzilla repo, and it's seeing my java plugin just fine... of course, a link to it is showing up in /usr/lib/mozilla/plugins, which may not be the case for you...
Everything in /usr/lib/mozilla/plugins:
flashplugin-alternative.so
librhythmbox-itms-detection-plugin.so
libtotem-cone-plugin.so
libtotem-gmp-plugin.so
libtotem-mully-plugin.so
libtotem-narrowspace-plugin.so
nppdf.soBut, as you can see by the image above, Firefox has Java listed. And I have all the necessary Java installed. No issues using Facebook's Java photo uploader in Firefox. SeaMonkey shows the "add plugin waning".
Very confused.
Nothing left to add as far as Java is concerned:

unclespellbinder@wombat:~$well well, apparently on karmic the sun-java6-plugin package does not install the alternative link in /usr/lib/mozilla, but only in /usr/lib/xulrunner-addons. this really is a bug that needs to be filed on launchpad, since /usr/lib/mozilla/plugins is an officially sanctioned directory where firefox should look for plugins.
try an 'ls -al /usr/lib/xulrunner-addons/plugins' or 'ls -al /usr/lib/xulrunner-1.9/plugins/' to see if the java link is there.
to fix this, either manually place a link to the plugin in /usr/lib/mozilla/plugins, or go all fancy and actually use update-alternatives to install an alternative location. the latter would look something like:
sudo update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /usr/lib/jvm/java-6-sun-1.6.0.15/jre/plugin/i386/ns7/libjavaplugin_oji.so 50just made a comment on this launchpad bug with this problem:
https://bugs.launchpad.net/ubuntu/+source/sun-java6/+bug/269136
no idea if anyone's going to pick up on it - it's an old bug, but since it's really right along the same lines, i figured it's better not to start a new one... but i may be wrong.

Never really understood the whole symbolic link thing. Could use some help on that.

try the update-alternatives command i posted above.
or if you really want to just make a link, you have to do it with sudo, because files in /usr/lib are owned by root (that's why the make link is grayed out for you - you're trying to create a symlink in a root-owned directory, which you don't have permission to do).
to make a manual link, run
sudo ln -s /usr/lib/xulrunner-addons/plugins/libjavaplugin.so /usr/lib/mozilla/plugins/libjavaplugin.soSleepy-zz-John said: Same trouble as Uncle Spellbinder; lost my Java in 2.0.2 when I upgraded from 1.1.17 in Karmic, whilst Java continues to work fine in FF 3.5.7.

the update-alternatives command should have installed a link in /usr/lib/mozilla/plugins. so, try
ls -al /usr/lib/mozilla/pluginsthen try /restarting/ seamonkey, and go to about:plugins to see if it's seeing the java plugin.

sudo ln -s /usr/lib/xulrunner-addons/plugins/libjavaplugin.so /usr/lib/mozilla/plugins/libjavaplugin.soThat worked. Just tested the Java photo uploader at Facebook, worked like a charm.
Thanks, nanotube. Really appreciate your help!

cool - no problem :)
just for future reference, the 'proper' way to add the java plugin link using update-alternatives is:
sudo update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so 50though functionally, a manual symlink does the same thing. the difference is that the alternatives system plays nicely if you happen to install another package providing the java plugin...
nanotube said: the update-alternatives command should have installed a link in /usr/lib/mozilla/plugins. so, try
ls -al /usr/lib/mozilla/pluginsYes, I do
lrwxrwxrwx 1 root root 39 2009-11-20 19:35 libjavaplugin.so -> /etc/alternatives/mozilla-javaplugin.so then try /restarting/ seamonkey, and go to about plugins to see if it's seeing the java plugin. No, it isn't :( There's Default Plugin File name: libnullplugin.so Then there's a long list of VLC Multimedia Plugin (compatible Totem 2.28.2) Then a long list of Windows Media Player Plug-in 10 (compatible; Totem) Then DivX® Web Player Then some QuickTime Plug-in 7.2.0 and finally a couple of Shockwave Flash
Your direct link code: ``` sudo ln -s /usr/lib/xulrunner-addons/plugins/libjavaplugin.so /usr/lib/mozilla/plugins/libjavaplugin.so
only returns:ln: creating symbolic link `./libjavaplugin.so': File exists
Still trying to figure out why it's working for Uncle Spellbinder,and not for me. My configuration must clearly be different somewhere #-oSleepy-zz-John:
ok, try removing the alternative:
sudo update-alternatives --remove-all mozilla-javaplugin.sothen install again (this time using a different java .so from the earlier one):
sudo update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so 50Oh wonderful! Many thanks nanotube - that works fine and my SeaMonkey's Java is back in business again.

super! :)
for reference: i posted a new bug report about this problem, with greater details and a patch, here: https://bugs.launchpad.net/ubuntu/+source/sun-java6/+bug/509727
Sleepy-zz-John,Uncle Spellbinder: by the way, it would probably be helpful if you go to that launchpad bug and post a 'me too' message, to help bring this to the attention of the packagers.
OK, done! Good support there. Thanks again nanotube

i saw that - excellent, thanks a lot :) hopefully they'll get that fix in soon.
