HowTo: Install Firefox / Google Chrome Java Plugin for Fedora 17

Step 1:
make sure your web browsers are close 

Step 2: (i'm using F17 64bit)
download and install jre-7u4-linux-x64.rpm from this java website http://java.com/en/download/manual.jsp?locale=en


Step 3:
open a terminal then type the following,
su -
updatedb
locate libnpjp2.so
copy the path of the libnpjp2.so file

Step 4a: (Firefox Users)
cd /home/user/.mozilla/plugins (replace user with your username)
ln -s path/of/libnpjp.so

Step 4b: (Chrome Users)
cd /opt/google/chrome/
mkdir plugins
cd plugins
ln -s path/of/libnpjp.so

Step 5:
run your browser

Bonus:
To open the java console, open a terminal (non-root account) then type
cd /usr/java/jre1.7.0_04/bin/
. ControlPanel

    So I guess I'm the second reader ;-)

    Thank you for providing a simple easy-to-follow how to. It works.

    I have some additional info that someone may find usefull.

    For 32 bit versions of Fedora, you must download the rpm named i586, e.g. jre-7u7-linux-i586.rpm, otherwise the procedure to install is identical.

    You can just use yum to install the rpm:

    # yum install jre-7u7-linux-i586.rpm

    It did complain a bit about not being able to open some files, but java works fine, so apparently it didn't matter...


    Thanks again :-)

    simple and easy...thank you...a lot...
    the paths were different but works like a charm now...

    cd /usr/lib/chromium-browser/plugins
    ln -s /usr/java/jre1.7.0_17/lib/i386/libnpjp2.so

    cd /usr/lib/mozilla/plugins
    ln -s /usr/java/jre1.7.0_17/lib/i386/libnpjp2.so

    It's bit quicker if you use IcedTea!

    su -c "yum install icedtea-web"

      I was having troubles trying to enable Java in Chrome under Fedora 19. This command did the job
      su -c "yum install icedtea-web"
      and it is the easiest way to eneable it.

      Thank you Nathan Holland for this link and thanks to renegadex for this blog.
