Red Hat Bugzilla – Bug 108063
Sun's Java JRE does not work with Red Hat after v.7.3
Last modified: 2007-11-30 17:10:32 EST
Description of problem:
After successfully installing Sun's Java JRE 1.4.2_2 RPM for Linux and creating
a symbolic link in the Mozilla plug-ins folder to libjavaplugin_oji.so
following the directons found at
http://plugindoc.mozdev.org/faqs/java.html...the plugins didn't work with
Mozilla or Mozilla Firebird on any version of Red Hat after 7.3
Version-Release number of selected component (if applicable):
1.2, 1.3, 1.4, 1.5
Install Sun Java JRE from http://java.sun.com
Steps to Reproduce:
1. Open a terminal
2. Change to your Mozilla (or Mozilla Firebird) plugins directory
3. Issue the following command: ln -s /usr/java/j2re1.4.2_01/plugin/i386/ns610-
Display prompts for installation of application/x-java-vm plugin
Java plugin works
Please note that I used the following command: ln -
gcc32/libjavaplugin_oji.so not the fore mentioned.
As i know there's some java versions, which does not work correct here.
Many people have reported that it works fine with j2re-SUN-1_4_2-linux-i586.rpm.
I tried jre1.4.2_1 without success. Mandrake 9.1 works fine with both versions
of java runtime, guess I'll have to reinstall Mandrake if Red Hat is unwilling
to address issue.

i have downloaded j2re-1_4_2_02-linux-i586.rpm from sun, and installed
it on my machine. It works fine for me with this version and mozilla-1.4.1-15
I did not find here the JRE 1.4.2_2 RPM, which you have!
please make sure that you have install the correct mozilla from Red Hat.
Sun's latest version of Java Runtime can be found at...
I used the version of Mozilla that came with the current Red Hat release.
Working with Fedora Core Severn 3.
From the web address you identified, you can get
It self-extracts, and you have to be sure to do
rpm -Uvh j2re-1_4_2_02-linux-i586-rpm.bin
In the Mozilla plugins directory, you need to do
And it works. It did not work for me with version 1.4.1_01, either.
Ok, downloaded the final release or Red Hat-Fedora followed your
instructions to the letter. Mozilla still did not recognize the java
vm plugin. I had to login as root to follow your directions, wouldn't
allow me to install as a user. It made the symbolic link fine but
when I launch Mozilla (the one that Fedora shipped with) and look
under plugins it's not recognize nor does it work on pages that
require the plugin. No offense but Mandrake 9.1 recognizes Sun's java
plugin immediately after the rpm install without additional effort on
my part (Red Hat 7.3 does the same thing). What has changed or what
isn't working that makes this so difficult to make Sun's java vm work?
you should check if there's a broken java plugin in following
I reinstalled the final release once again, followed all the
instructions given by you and Mozilla. The plugin and sybolic links
are where they're supposed to be and still do not work or show up in
the Mozilla browser under the plugins information. Flash and
Realplayer plugins work fine. I have an Intel system board with an
810 chipset, 600Mhz with 512Mb SDRAM. Once again, as I have stated
before, Sun's Java has yet to work with any Red Hat release since
v7.3 and no one can tell me why. Many other people have the same
problem as well. Will you guys please fix this so that the user
doesn't have to jump through 10 hoops after installing Sun's Java RPM?
Download J2SE v 1.4.2_03 - SDK, execute the .bin-file, install the
rpm, then make the symbolic link with ln -s
/usr/lib/mozilla/plugins, and then restart mozilla. Works! I don't see
I suggest to close this bug report.
So what you're saying is that unlike other linux distributions such
as Mandrake and Debian in which you only have to install the JRE, the
SDK (software devlopment kit) is required under Fedora in order for
Sun's Java VM to work within the Mozilla browser? Somehow that seems
incorrect but I'll give it a try.
I tried what you suggested without success. I find it ironic that Red
Hat/Fedora requires manual configurations to begin with much less the
Java SDK. Most linux distributions only require that you simply
install the java JRE with no additional effort on the part of the
user (as it did with Red Hat 7.3). The creation of sybollic links
should not be required, this seems to be a design flaw within all the
Red Hat releases since 7.3.

No, that's not what I said.

I understand that you're having difficulties, and that you need
support. I'm not convinced that there is a bug. Let's continue this
conversation on the fedora users mailing list or on usenet.
I suggest to close this bug report.
Ok guys, I downloaded the final release Fedora Core again (noticed a
few changes since the previous one) and Sun's Java VM now works.
Thanks for all your help, I'm using Fedora Core now.
