Trouble installing java 6

[daegan_xavier]

Hi,

I'm having a hard time getting Java to work. I've got Ubuntu 8.0.4 and Firefox 3.0.8.

Here's what I have done:
Using Add/Remove I have installed
Sun Java 6 Runtime
Sun Java 6.0 Plugin

However about:plugins does not show the java plugin - should it?

I followed the instructions here
https://help.ubuntu.com/community/Java

When I run java -version I get this:
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)

However when I test if Java is installed at java.com it says that JDE is not working.

Can anyone help? I'm muddling my way through the instructions but I am reluctant to embark in more complicated processes as I am definitely a beginner at all this.

Thanks,
Daegan

Are you running i686 or x86_64?

Applications -> Accessories -> Terminal

uname -m

[daegan_xavier]

I'm running i686.

What's the output of this command from a terminal?


sudo apt-get install sun-java6-plugin

Do you have a site in mind that requires a java plugin that you can check out (besides the testing site from Sun)?

[daegan_xavier]

http://thinks.com/daily_crossword.htm
was the motivating site for realizing that Java wasn't working correctly... and it still isn't.

[taurus]

You did reboot, right?

From firefox address field, type this in and post the output (or screenshot) of it.


about:plugins

[daegan_xavier]

Actually, I hadn't rebooted (oops!) But I just did, and re-tested the thinks.com site, no luck.

I don't see java plugin anywhere on the list.

[daegan_xavier]

Neither do I, I don't know how to install it. From what I understand with the earlier 'sudo apt-get install sun-java6-plugin' it should be installed?

[taurus]

Yes and so does this (unless you are running x86_64).


sudo apt-get update
sudo apt-get install ubuntu-restricted-extras


uname -m

[daegan_xavier]

I ran the two sudo codes, do you want me to post the results?

uname-m still gives i686.

[taurus]

What's the output of this command?


ls -la /usr/lib/mozilla/plugins

[daegan_xavier]

It gives:

drwxr-xr-x 2 root root 4096 2009-04-04 09:27 .

[taurus]

How about


ls -la /usr/lib/firefox/plugins

[daegan_xavier]

[taurus]

Did you install firefox from the repos or did you install it by hand?


ls -la ~/.mozilla/plugins

[daegan_xavier]

It was a work setup computer - I imagine they installed from the repos, but I can't be sure.

latest result:
ls: cannot access /home/idilia/.mozilla/plugins: No such file or directory

[marcha23]

I think that symbolic link in /etc/alternatives/mozilla-javaplugin.so is broken. Try to fix it by adding manual. So as I have 64 ubuntu and java 6 u 13 I have to add sudo ln -s /usr/lib/jvm/java-6-sun-1.6.0.13/jre/lib/amd64/libnpjp2.so /usr/lib64/firefox-addons/plugins/ .

Then you probably have to do
sudo ln -s /usr/lib/jvm/java-6-sun-1.6.0.07/jre/lib/i386/libnpjp2.so /usr/lib64/firefox-addons/plugins/

Any way suggest you to update java to java 6u13.

[daegan_xavier]

Hi Marcha23 -

I tried the
sudo ln -s /usr/lib/jvm/java-6-sun-1.6.0.07/jre/lib/i386/libnpjp2.so /usr/lib64/firefox-addons/plugins/
as you suggested - no luck on any java sites.
I would love to update to java 6u13, but I've had enough trouble setting up java here - I took the version from the Add/Remove menu because I was never able to get anything I downloaded from the java site to work.

Perhaps this is just out of my league.

[daegan_xavier]

Quick update - I updated to Jaunty and the plugin was there, no problem. Thanks to all for your help.
