Trouble installing Java

The Stranger · 04-24-2005, 08:21 PM

I am trying to install the java plugin for Firefox browser and having a devil of a time doing it. I am new to all this and am trying to follow the instructions, but I keep hitting a wall.

I have unpacked the files into a directory and now wish to make a link from that directory to the firefox plugin directory but I keep getting this error:

bash: In: command not found

what does this mean and how can I fix it?

The command is ln. As in 'el en'

Hey thanks, boy do I feel kinda dumb.

So I tried to I guess "soft link" libjavaplugin_oji.so from the one directory to the other and this is the message that I get:

ln: invalid option -- /

what does this mean?

Your going to have to post the exact command you typed for anyone to help

The Stranger · 04-25-2005, 12:55 PM

Oh geeze sorry about that.

Okay the issue that I have is that I want to link a file from one directory to another and it was suggested that I do it this way:

ln -s/home/<username>/firefox-installer/plugins/j2re.1.4.2_08/plugin/i386/ns610-gcc32/libjavaplugin_oji.so `/home/<username>/.mozilla/plugins/libjavaplugin_oji.so

now initially I was getting:

ln: invalid option -- /

Now I just get:

> on the left side.

It does not appear to be making a link to the requested folder. Is my syntax wrong?

You need a space between the -s and the / at the beginning: ln -s /home

There appears to be an apostrophe before /home in the second line which you don't need. Assuming the libjavaplugin_oji.so is actually in your .mozilla/plugins folder, this looks like it will work. I'm using SUSE 9.2 and this plug in is in my /usr/java directory.

Thanks for the help!

This might be a silly question but from what you can read above, is it linking a file from the firefox-installer/plugins to ./mozilla/plugins? That is what I am trying to do. I looked in my Java directory and there was nothing in it.

I will try your suggestion when I get home. I know the directories look a little funny. I am used to windows doing all the work for me and am still trying to figure out where things go. When I installed firefox, it just created a folder in my /home/username directory. I also had to install it in root as well so that I could use it. If I were to install it as /root, would I put it in the /usr/local directory so that all accounts could use firefox?

Thanks again

I'm not sure why you needed to install Firefox as user and root. I only installed it as user in /home. The link for java needs to go from the directory with libjavaplugin_oji.so to the firefox plugins directory. So first you're going to have to find libjavaplugin_oji.so. You can use the locate or whereis command to help you find it. On my system the link looks like this:

ln -s /usr/java/jre1.5.0/plugin/i386/ns7/libjavaplugin_oji.so /home/username/firefox-installer/plugins/libjavaplugin_oji.so

Thanks again for the help. I tried it out and it seemed to work, however, java still does not work when I try it on the net.

Could it be that FF looks for it elsewhere? I will try and add a link in the java folder like yours.

OK, I just figured out how it works. Note, I have SuSE Professional 9.2, the box set. YMMV.

First, SuSE comes with Sun JVM 1.4.2, in fact Open Office is dependent upon that being loaded, so chances are you already have a Java virtual machine.

Second, you will need to explicitly select Java Plugin from the Software Installation, it doesn't come with the base jvm used for OpenOffice. Go to Yast and do a search on "java-1_4_2-sun-plugin", or just search on "plugin" and look at the results list carefully.

Third, just to make it confusing, if you are running YOU and update regularly (as you should), then you have probably updated the JVM and YaST doesn't like to install the older version of the java plugin to the patched JVM. So, what I did (and I'm sure there is a more straightforward way) was to downgrade java, install the java plugin (both from the DVD), then upgrade both.

Fourth, if you've been messing around trying to install Java, you probably have a bad link in your plugins directory. For Mozilla, look for a dead soft link in /opt/mozilla/lib/plugins. For Firefox, look for a dead link in /opt/MozillaFirefox/lib/plugins. In either case, delete it. You should also see a good link (since you have installed the Java plugin from SuSe, right?).

That's it. I'm sure you could be more efficient using an online source of packages to just add the latest patched plugin for your JVM. I have no idea what the story is with 9.3 or if you have the free download.

Good luck,

Dave Rose

I am looking to use the RPM on Sun’s site to upgrade the Java on my SuSE (Java v1.4.2).

When I try to remove the package (RPM) with YaST the following comes up:

You should be able to upgrade java through YOU.

Jongi · 06-06-2005, 01:36 PM

What is YOU, where can I find it and how do I use it?

Jongi · 06-06-2005, 01:38 PM

Just figured out it is YaST Online Update

xgm · 06-13-2005, 03:26 AM

I just installed Java 1.5.0_02 in9.2 from the konsole, just following the Java site instructions . Note that for the plugin to work , the syntaxis must be pretty accurate:
-put a space after the "ln -s "
-write all the name:"jre1.5.0_02"
-after "_oji.so" make "space-dot".

Did it work?
