Cool jre link to browser problem


GREETINGS,
I was finally able to install Sun's JRE-1.5.0.04 Version of java onto a computer running Ferdora Core 3. I was able to link Openoffice to it also. The problem is this... when I made a plug in link to Firefox I first use the link commands for an earlier version of Mozilla then a later version of Mozilla and finally to Firefox. I have Java enabled , but Java does not work. Firefox tells me I need to add the plugin manually. Can anyone help ?

hmm, i'm not sure what you did to link in the old virtual machine, but for me it was:

cd ~/.mozilla/plugins/
ln -s /usr/java/jre1.5.0_02/plugin/i386/ns7/libjavaplugin_oji.so

then, I restarted firefox, and it worked like a charm

jre not linking to browser

Issue the following command: ln -s /usr/java/jre1.5.0_03/plugin/i386/ns7/libjavaplugin_oji.so ./libjavaplugin_oji.so

The above command is what I tried. I installed it in /home/ directory not /usr/ and made the change. Could my other links to older Mozilla versions cause a problem?

How about... /usr/lib/jre
1.5.0_03/plugin/i386/ns7/libjavaplugin_oji.so That's where it should be.

Have you tried what timcharper had suggested? Here is where I have my symlink for java located for Mozilla.

/usr/lib/mozilla/plugins

Yes I tried what was suggested. I noticed I have these folders , but no information in them.
/usr/lib/java-1.5.0
/usr/lib/java-1.3.0
/usr/lib/java-1.3.1
/usr/lib/java-1.4.0
/usr/lib/java-1.4.1
/usr/lib/java-1.4.2
This is the location of the installed jre /home/cheryl/java/jre1.5.0_04

OK, this may help or not; again, here is the Symlic I created inside /usr/lib/mozilla/plugins

lrwxrwxrwx 1 root root 58 Jul 23 11:00 libjavaplugin_oji.so -> /usr/java/jre1.5.0_02/plugin/i386/ns7/libjavaplugin_oji.so*

The key is to locate this file:

libjavaplugin_oji.so

and Link it to your FireFox Plugins directory wherever that may be... Like I said mine (I use Mozilla is here:

/usr/lib/mozilla/plugins

So if your plugins for firefox are located here:
/usr/lib/firefox/plugins

and your libjavaplugin_oji.so is locatede here:
/home/cheryl/java/jre1.5.0_04

Then in root:

cd /usr/lib/firefox/plugins <enter>
ln -s /home/cheryl/java/jre1.5.0_04/libjavaplugin_oji.so <enter>

Hope this clearifies a little

Unhappy

I see what the goal is now and I have not been using the exact location of the (libjavaplugin_oji.so )file, but
with all of the correct directories used I get ( ln: `./libjavaplugin_oji.so': File exists) . Do I now have a problem with permissions not allowing write? Owner ( root ) does have write permission.

Ok, so it's probably because you have some other invalid links already there that are pointing in the wrong place... you can use rm to delete the link but first if you can give us a listing of your plugins directory... Then we can see what's exactly in their...

/usr/lib/firefox-1.0.6/plugins/ns7-gcc29
/usr/lib/firefox-1.0.6/plugins/ns7
/usr/lib/firefox-1.0.6/plugins/libnullplugin.so
/usr/lib/firefox-1.0.6/plugins/libjavaplugin_oji.so

This is what is there. Thanks for you help. I wondered if I made a bad link by not really knowing what I was doing. I might need a hand in using the delete command. At one point I was told I have mail after performing a link command. Was that something I had done. I don't even have this computer running as a server. I also am not clear on what application will read mail. I tried (gedit) but no soap. This is where it said my new mail was while logged in as root . . /var/spool/mail

Sorry was not clear enough... do an:

ls -l

to get the full listing like this:

lrwxrwxrwx 1 root root 58 Jul 23 11:00 libjavaplugin_oji.so -> /usr/java/jre1.5.0_02/plugin/i386/ns7/libjavaplugin_oji.so*

This will tell you the actual file name... It is most likely "libjavaplugin_oji.so" but it is possible to give symlinks other names and we want to make sure... You will want to delete the file before the (->) witch only shows where the link is followed...

In the case of the example above I would remove the symlink like this...

rm -f libjavaplugin_oji.so

It belongs to root so I must enter "su" mode before I can do this...

Remember your not deleting anything realy but just a link so don't worry to much about it...

OK, this indicates that the your actual file is located in /libjavaplugi n_oji.so

so:

rm -f libjavaplugin_oji.so

then:

make your link with the correct path to your file...which I still don't know where in your case..

What do ya know it works.
I can now work my site with Linux for the 1st time ever! Tried before but jre installing and browser linking just seemed too complicated at the time. I learned a lot this time around, so thanks for your help.
P.S. How hard is it to fetch mail from /var/spool/mail ?

Alright I am having a similar problem though its possible I have not even installed the java plugin like I thought. Hmm I don't even know where to go from here to describe my problem.

I followed the directions on the sun java download area and everything seemed to work until I go to the linking part. But I am not certain how to check whether the java is installed or if when I attempted to create the link it made a bad link. or heck who knows maybe even I made a good link and something else is wrong.

I am running Fedora Core 4 and Mozilla Firefox.
