Hi,
I'd like to install a working Java Plugin for Firefox, and I wonder how to go about it. There's some documentation available online, but one quickly gets the feeling it's quite a mess. I also admit being a contributor to the mess, since the Linux book I published in June 2009 gives a detailed - and now obsolete - description about installing JRE :
http://www.microlinux.fr/linux_aux_petits_oignons/chapitre_8/01.php#java
Any advice on how to go about that without jumping through burning loops? A pointer to some concise documentation or, even better, a short and working step-by-step HOWTO?
Cheers,
Niki Kovacs

The problem may be that in Firefox 3.6.6 (or some time close to that) the name of the Java plugin changed. It is no longer libjavaplugin_oji.so, rather it is now libnpjp2.so. It also changed locations within the installed JRE as well. If you have the current JRE installed, you should be able to get it working with the following command run as root:
ln -s /usr/java/latest/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/

yesterday, i resolved the issue.
type about:plugins in url box, then there is a link to firefox plugin document.
at first, i used firefix-3.6. the java plugin always did not work. later, i changed the jdk version. it still not work. last, i changed to used firefox-3.5, then it's OK.
therefor, you can change the firefox version to 3.5.
notice, link /path-to-jre/plugin/i386/ns7/libjavaplugin_oji.so to ~/mozila/plugins, not copy.

Hi,
I missed the most posts of the thread so let me say those few words.
First of all I use Java or OpenOffice.org from producers' websites. They are always "fresh" and installable in RHEL.
I assume too, that the i386 and amd64 versions work the same way, only the lib names can be different.
Thirdly, I cannot say now what method I used lately but either of them worked flawlessly. I installed Scientific Linux (CentOS) several times without any snags.
So,
1. The latest Java is attached to the latest OpenOffice.org RPMs. http://download.openoffice.org/other.html
2. Java RPM can be downloaded from Oracle page: http://www.java.com/en/download/linux_manual.jsp?locale=en&host=www.java...
test Java: http://www.java.com/en/download/help/testvm.xml
Java directory with Java libs and plugins: /usr/java/jre1.6.0_21/lib/amd64
I use to place OpenOffice.org in /opt directory. Java is installed here: /opt/openoffice.org/ure
It must be working as it always worked here. ;-)
Best regards, Przemysław Pawełczyk

Hi,
A few words on plugin directories.
Typical Linux directory /usr/share/mozilla/plugins does not work here. The right place for plugins in RHEL amd64, as in my 64bit example, is: /usr/lib64/mozilla/plugins.
I had to find out that because the libnpjp2.so library wasn't placed in user's ~/.mozilla/plugins directory and what made me so confused wondering why my Firefox 3.6.11 read the java pages without the library! :-)
Summing up - the best way to find out what works or why something doesn't is a "small step approach" - trying to make use of the latest libs or apps from developers websites - not from the main repos for our system releases.
Regards
I use fedora i386. After i link the jre plugin file to user's ~/.mozilla/plugins directory, they both work very well.

Hi,
Of course, I only wanted to point to another directories where one would be able to place JRE and other plugins.

These links haven't been updated in long time, it seems. Come on, flash player version 9?

therefor, you can change the firefox version to 3.5.

I think that'll help your situation.
