Howto - Java JRE plugin on Firefox for Fedora 14

[thyristor]

Hi, I searched during a couple of minutes on google how to run a java application on a 64 bit Firefox install on Fedora, but I didn't find any simple and direct way to do it.
So I'll post this here, hoping that people who search for this problem can easily find this really quick solution.

1-> on the terminal do the usual su -
2-> yum install jre
3.> make a link in /home/your_name/.mozilla/plugins/ folder to the file located at /usr/java/jre1.6.0_23/lib/amd64/libnpjp2.so
(just select the file, press ctrl+shift and drag it to the plugins folder)
4-> go to http://java.com/en/download/installed.jsp from firefox and test your install

Piece of cake, but it doesn't show up in search engines that easily when I look for: jre firefox 64 plugin fedora
Granted that many tutorials mention the linking method, but most either tell you to install the binary/rpm from the java site or even installing the 32bit version for older fedoras... yum makes it so much easier.

I'm using 32 bit Fedora 14, and I cannot get this to work. As soon as I tried to move the "libnpjp2.so", SELinux came up and said there were multiple errors, and that it shouldn't EVER encounter this error.

This is all you needed to do (below) then restart, (you dont need to make links or do anything else)

yum -y install java-1.6.0-openjdk-plugin

Thanks very much. That one command did what I needed. I don't know why people were saying to make symlinks for.

With that being said, I was unaware I was even running 64 bit Firefox. I think I was running 32 bit FF before I upgraded to Fedora 15 (and therefore Firefox 4). I think Chrome was 64 bit all along. Chrome doesn't work, but I don't really care, I just need one browser that can do what I need, and since FF is my main, all the better.

I didn't even know there was 64 Bit Firefox (let alone that I was using it, like I mentioned before). Is there 64 Bit for Windows too, or just Linux?

I don't see anything about 64 bit there.

The 64bit is not very official at mozilla, they mostly give out the 32bit one on the main page. But if you go in the mozilla ftp site, you can get the 64bit one here

ftp://ftp.mozilla.org/pub/firefox/releases/latest-4.0/

in the "linux-x86_64" directory. There's no windows 64bit there

So did the Fedora team compile the code there and use it for Fedora 15? How come there is a Linux one but no Windows one? Is it because they only want people who are tech savy to use it, so they only make it for Linux?

While that worked for me, I was not able to search for that package. When I do

yum search java-1.6.0-openjdk-plugin

it returns nothing. Does anyone know the cause of this?

[bucketmouse3000]

The 'java-1.6.0-openjdk-plugin' package is no longer in the official repositories. It has been superseded by 'icedtea-web'.

After installation of 'icedtea-web', run ' alternatives --display libjavaplugin.so' and take note of the location of the icedteaplugin. next, as root, navigate the the mozilla plugins folder ( 'cd /usr/lib/mozilla/plugins/') and run 'ln -s /path/to/icedteaplugin.so'.

Before running

yum -y install java-1.6.0-openjdk-plugin

worked (I haven't tried since last I checked it was still working) but for next time do I just yum install icedtea-web instead?

That is correct.

That's because you tried to link a 64-bit library (/usr/java/jre1.6.0_23/lib/amd64/libnpjp2.so) on a 32-bit OS.

32-bit Fedora runs the standard Java rpm just fine -- it's the 64-bit stuff that there was a problem with (IcedTea takes care of this rather nicely, as per the follow-up messages).

I made a shellscript for this. If you need wget just uncomment the install line.

#!/bin/bash
echo "Downloading Java"
#yum -y install wget
wget http://download.oracle.com/otn-pub/java/jdk/6u27-b07/jre-6u27-linux-i586-rpm.bin
echo "Making executable"
chmod a+x jre*
echo "Installing java"
./jre*
cd /usr/lib/mozilla/plugins
echo "Making symlink so Firefox works"
ln -s /usr/java/jre*/lib/i386/libnpjp2.so

Doesn't wget come with Fedora?

It depends what version of Fedora you install. The stripped down versions don't have it.
