firefox java plugin?

derailed · #1 12th March 2005, 02:33 PM

hey everyone. my problem is that i cant load any java from websites. i downloaded sun java software and installed it and followed all the instructions that came with it. i then went to the test page and still, 'plugin missing', i searched here for help and followed all those instructins, still nothing. i think the problem is that java is installed properly, but firefox wont use the plugin. im out of ideas. please help!!!! i want to stay away from xp, but java is important for me and that may be the only solution.

You have java and the plugin installed, you just need to inform firefox of the situation.

as root:

Quote:

cd /usr/lib/firefox-1.0.1/plugins
ln -s /usr/java/jre1.5.0_01/plugin/i386/ns7/libjavaplugin_oji.so

The above assumes FC3 with Firefox 1.0.1, i386 distribution. If details differ, make appropriate changes.

It was the plugin issues I had with firefox which led me to dump firefox/thunderbird and go back to the Mozilla suite, which includes the browser and moz-mail. It comes with a couple dozen or so pre-compiled and installed plugins, including all the java/j2re, flash, realplayer, etc. For me, Mozilla suite is far superior to firefox.
Just my opinion....

I think I have JAVA installed

[root@murfs plugins]# java -version java version "1.4.2_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_0 6-b03)
Java HotSpot(TM) Client VM (build 1.4.2_06-b03, mixed mode)

But /usr/java is empty

So I looked for javaplugin

[root@murfs plugins]# locate libjavaplugin
/usr/lib/netscape/plugins/libjavaplugin.so
/usr/lib/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so
/usr/lib/jre/plugin/i386/ns610/libjavaplugin_oji.so
/usr/lib/jre/plugin/i386/ns4/libjavaplugin.so
/usr/lib/jre/lib/i386/libjavaplugin_jni.so
/usr/lib/mozilla/plugins/libjavaplugin_oji.so
[root@murfs plugins]#

And created a link from /usr/lib/firefox-1.0.1/plugins to each in turn and tried a Java site. Firefox shutdown instantly each time.

it worked. thanks so much. ive been trying to do that ln..... .so command so many times and i dont know why it didnt work. yours did. anyway, i also prefer mozilla because that is what i used on my xp box. anywho, java works perfectly and im excited. 2 quick questions. 1: will i have to worry about java viruses and applets like in xp? 2: when i install something using the ./install command, how do i uninstall (this one is general). thanks guys

I'm glad you got it working. My thought is, why re-invent the wheel, when Mozilla suite has it all packaged for you, no muss, no fuss.
As far as security is concerned, I've never picked up a virus since moving to linux. There is a cool security check site where you can test the security of your machine. Check it out; http://scan.sygatetech.com
If you dual boot with Windows or have Win4Lin or such running, you might consider clamav for virus scanning of your mail, etc. You can get clamav from the apt repositories.... probably yum, too. As I said, though, I haven't had a virus on my machine since I came over to linux..... 17 months, now.

i agree about mozilla. but fc3 came with firefox and im not that sly about uninstalling and installing programs. i use bitdefender and im quite excited about it. i know its hard to get virus on linux, but i wanted to make sure since java is a crossplatform application. anyway, thanks everyone for the help.

[COLOR=Magenta]I am also having the same problem of applets not running in Mozilla as well as firefox.

However i have installed jre1.5 and also created the link in the plugin directory.

My Operating System is FC3.And browser is closing without starting due to the link.[/CO

Firefox also looks in the generic directory /usr/lib/mozilla/plugins for plugins, so you can put your plugins there so as not to have to fix them each time Firefox is updated. Also, Sun just released a new Java version 1.5.0_02.

robatino · #10 13th March 2005, 07:34 PM

I should have mentioned that on my FC3 box, the directory /usr/lib/mozilla/plugins is owned by 3 packages: mozilla, kdebase, and firefox. So at least on FC3, even if only Firefox is installed, this directory is guaranteed to exist. I think the reason there is no generic /usr/lib/firefox/plugins directory is that there was a decision to use /usr/lib/mozilla/plugins instead, so if someone has both Mozilla and Firefox installed, they only need to put version-independent plugins in the one directory. Plugins which are version-dependent would go in /usr/lib/mozilla-xxx/plugins or /usr/lib/firefox-xxx/plugins.

damit, it's useless! i still can't get java running. it doesn't matter, wher do i install the plugin or weather i link it to the firefox or not. i tried the installing it to /lib/java and linking into firefox:

ln -s /usr/java/jre1.5.0_01/plugin/i386/ns7/libjavaplugin_oji.so

no differnes. then i tried installing it directly under the firefox/plugins.. no!

and when i tried to locate the plugin, as somebody recomened by typing locate libjavaplugin - it doesn't give me any result, what so ever.

any ideas?

tnx

derailed · #12 15th March 2005, 10:14 AM

its a stupid question, but are you sure java is installed in the first place?

sportphantom · #13 15th March 2005, 10:22 AM

i'm staring to doubt about it myself if locate libjavaplugin doesn't respond. still, i did all it's said in da man - downloaded, gave rights (chmod a+x), installed it and linked it to the firefox plugin folder as i described earlier..

now, where's the bug?

as root, do this:
updatedb

That updates the file location database used by locate.

Here's what I get when I type "java -version" in a terminal:
[allen@anubis ~]$ java -version
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode)
[allen@anubis ~]$
Assuming you have FC3, your java plugin should be at: /usr/java/jre1.5.0/plugin/i386/ns7/libjavaplugin_oji.so
Make sure you have java installed, then make the symlink as instructed in the post by Crystal Cowboy.
Open a terminal: get root priviledges FIRST: $ su
Then do the following:
# cd /usr/lib/firefox-1.0.1/plugins
# ln -s /usr/java/jre1.5.0_01/plugin/i386/ns7/libjavaplugin_oji.so
Again assuming your on FC3 with the latest Firefox. Should work just fine with no problems.
By the way, how did you install your java (if it's installed)? With YUM or APT/Synaptic or did you just download it from Sun?
