CentOS

I'm a long time Linux user but I'll be darned if I can get Java applets to work in Firefox on Centos5.

I download/executed the jre ".rpm" file from Sun.

I created the symbolic link as follows.

#cd /usr/lib/firefox-1.5.0.9/plugins
#ln -s /usr/java/jre1.6.0/plugin/i386/ns7/libjavaplugin_oji.so .
#ls -l
libjavaplugin_oji.so -> /usr/java/jre1.6.0/plugin/i386/ns7/libjavaplugin_oji.so

I stopped/started Firefox.

Ran Sun's Java test at the following site.
http://www.java.com/en/download/help/testvm.xml

Test fails!

I give up. What am I missing?

Do I need to download another jre? Maybe IBM's will work?

Java block is checked in Edit-Preferences->Content.

Try putting the symlink in /usr/lib/mozilla/plugins
instead.

Thanks gerald. But still no joy.

I assume java works for others. If so, where did you get your Java runtime? Did you change anything in Firefox config?

You are running 32 bit firefox, right?
If not, search the forms for the plugin wrapper.

On my CentOS 4.5 workstation, my firefox is in /usr/local/firefox. I use the following link in /usr/local/firefox/plugins:

libjavaplugin_oji.so -> /usr/java/jdk1.5.0_11/jre/plugin/i386/ns7/libjavaplugin_oji.so

It works fine.

If you bring up firefox and put in the url "about:plugins" does the java plugin show?

Yes. "about:plugins" does display the plugin version that I have installed.

I see you're running CentOS 4.5 and not CentOS 5. Maybe there is no CentOS 5 java plugin yet. The installation instructions on Sun's site are clearly out of date. They talk about checking Tools->Options->Java. That doesn't even exist in Firefox 1.5.0.9. So maybe their plugin is out of date also. That's why I'd like to know if anyone using CentOS 5 is able to run java applets.

I wonder if it's possible to download Java plugin source and build it myself? I dunno.

Is java plugin available in any of the CentOS repositories? I looked but I didn't see anything.

This is over my head. I'm lost!

I don't really see how CentOS 4.5 vs 5.0 makes a difference here. What's really involved is Firefox and Java, regardless of the CentOS distribution level.

BTW, I am using Firefox 2.0.0.4, but I have never seen Java fail to work on any version of Linux when the plugin shows up in about:config.

You've got me baffled on this one.

Having not upgraded any systems from jre-1.5 to jre-1.6, I decided to have a look at this one.

After downloading/running the i586 package, I noticed that the rpm was unpacked, but was not installed, so I ?rpm -ivh ...? and it installed without issues. Haven?t seen that happen before.

Then removed the old jre package and:

[code]# [b]cd /usr/lib/mozilla/plugins[/b]

# [b]rm libjavaplugin_oji.so[/b]

# [b]ln -s /usr/java/latest/plugin/i386/ns7/libjavaplugin_oji.so[/b][/code]
Note the link to ../latest/... Nice feature for future use.

As with jre-1.5, using jre-1.6 with firefox.i386 works fine.


And back to gerald_clark?s question: ?You are running 32 bit firefox, right??

[code] # [b]uname -rpmi[/b]

2.6.18-8.1.6.el5 x86_64 x86_64 x86_64

# [b]yum list installed firefox jre[/b]

firefox.i386 1.5.0.12-1.el5.centos installed
jre.i586 1.6.0_01-fcs installed[/code]

Here's mine. I don't know how many bits it is.

# uname -rpmi
2.6.18-8.el5 i686 i686 i386

# yum list installed firefox jre
Loading "installonlyn" plugin
Installed Packages
firefox.i386 1.5.0.9-10.el5.centos installed
jre.i586 1.6.0-fcs installed

Looks ok, no?

Maybe I'm not testing it right. All I know is the little animated puppet applet doesn't appear when I go to Sun's Java test site mentioned previously.

My puppet wiggles. :lol:
