No Java in FF or Konqueror

[0xygenMask]

Hi

I've installed 7.10 last night, 64 bit version and as far as I can tell, everything seems to be running except Java. I have installed it using Add/Remove wizard, and accepted the T&C when asked during the installation. But when I tried to view web pages with Java embedded, I get message saying plugin not installed.... I also get the same message when viewing web pages using Konqueror.

Any idea of how to solve this?

Thanks

Re: No Java in FF or Konqueror

Which package have you installed?
Have you tried it on several pages?
It works for me after install sun-java6-plugin or j2re1.4-mozilla-plugin packages

Re: No Java in FF or Konqueror

Yes, I have been to several sites including the official Java page I've even tried uninstalling and reinstalling the apps, still getting the same result

Re: No Java in FF or Konqueror

humm... I think that firefox plugins are stored in /usr/lib/firefox/plugins/
Check that you have a libjavaplugin.so file there.

Probably it will be a link. In my case is a link to /etc/alternatives/firefox-javaplugin.so, that is again a link to /usr/lib/jvm/java-6-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so
This file is from sun-java6-bin package.

sun-java6-plugin package looks almost empty, so I guess that it only makes the links in the firefox plugin directory to the right files, but you need it.

Re: No Java in FF or Konqueror

If that doesn't work, try installing the icedtea-java7-plugin (if you're on Gutsy); you can also install the ubufox package which will integrate Firefox better with (K)Ubuntu and allow you to install the Firefox plugins from the repos within Firefox.

Thanks for the info, I think I will have to look into this a little bit more as I don't have ...plugin/i386/ns7/libjavaplugin_oji.so in my 'jrv' file, only the 'bin','liv' and 'man' file.

This may partly explain why my Java isn't working

Re: No Java in FF or Konqueror

eismann has it right, I think. If you have Java but not as a plug-in, then you must build your own plug-in using soft links. Not difficult, but detailed, and we could help if you go that way. That is to say, sun-java6-jre is only JRE (Java Runtime Environment), not the plug-in link to FX.

Or, easier:

sudo apt-get install sun-java6-plugin

gets you Java (JRE) and sets it up as the FX plug-in for you.

Test it:
JAVA test site (Java Runtime Environment, JRE): http://java.com/en/download/help/testvm.xml
(If you have NoScript as a Firefox add-in, you must click on the NoScript icon "temporarily allow java.com" to run this test.)

Nope, I just tried it and got this -

compaq:~$ sudo apt-get install sun-java6-plugin

Re: No Java in FF or Konqueror

Worked for me in Feisty just now. (I haven't yet got Gutsy up to test it there.)
It fetched a bunch of needed stuff and went ok:

http://packages.ubuntu.com/feisty/web/sun-java6-plugin
(multiverse)

mike@mike-desktop:~$ apt-cache search sun-java6-plugin
sun-java6-plugin - The Java(TM) Plug-in, Java SE 6

Mehh. No such package on Gutsy 64-bit.

Re: No Java in FF or Konqueror

Gosh, too bad. Thought I had this one nailed down.

Back to eismann's idea of manually making the link which makes the plug-in:

I did this in Kubuntu 6.10 kernel 2.6.17-11. Hope link technology hasn't changed in Gutsy

Summary of the method:

Install Firefox. Install JAVA Runtime Environment. So now you just have to make a link from the Firefox plugins directory to a special JAVA file (used for this purpose).
Open Konsole.
Navigate to your Firefox plugins directory using cd (change directory).
From there, make a symbolic link to the file libjavaplugin_oji.so (which is located within your JAVA files).

To show an example of the method:
The hard part (if there is one) is clicking around in Konqueror to find where everything is. Or, at Konsole, using the find command:
find / -name the-name-of-the-thing-I'm-looking-for -print

My Firefox plugins directory is /usr/lib/firefox/plugins .
The path to the JAVA file libjavaplugin_oji.so is: /usr/lib/jvm/java-6-sun-1.6.0.00/jre/plugin/i386/ns7/libjavaplugin_oji.so .

So, at Konsole:

cd /usr/lib/firefox/plugins
ln -s /usr/lib/jvm/java-6-sun-1.6.0.00/jre/plugin/i386/ns7/libjavaplugin_oji.so
exit

That's it -- your download is now a FX plug-in.

Re: No Java in FF or Konqueror

I believe the sun-java6-plugin has been replaced by the icedtea-java7-plugin in Gutsy, which was what I was prompted to install when I attempted to load a web site requiring Java (I have the ubufox package installed). I'm not wasting my breath, I'm really quite sure it is the package you need if you're running Gutsy, I mean, unless you just feel like creating your own plugin.

Re: No Java in FF or Konqueror

Well, I think I'm on the right track. When I installed the icedtea plugin, the 'missing plugin' message from FF have disappeared. The problem now is that FF crashes when I try to test it at the Java site

Re: No Java in FF or Konqueror

Do you have the flashplugin-nonfree, libflash-dev, libflash-mozplugin, and libflash0c2 packages installed?

[0xygenMask]

Re: No Java in FF or Konqueror

Yes to all the above, but I don't understand why you're asking about flash plugin...
