FC4, Firefox 1.0.4 and JRE 1.4.2


Ok, I have never had this problem before. I have always been able to get java working with Firefox.

This is what I am doing and the results.

I make a symbolic link from /usr/java/j2re1.4.2_08/plugin/i386/ns4/libjavaplugin.so /usr/lib/firefox-1.0.4/plugins

Java doesn't work.

So I deleted that symbolic link and did this.

ln -s /usr/java/j2re1.4.2_08/plugin/i386/ns610/libjavaplugin_oji.so /usr/lib/firefox-1.0.4/plugins


Now my browser doesn't work, it won't even start. So I delete that symbolic link and I type in

ln -s /usr/java/j2re1.4.2_08/plugin/i386/ns610-gcc32/libjavaplugin_oji.so /usr/lib/firefox-1.0.4/plugins.

Now when I try to access something online that I need java for the browser shuts down.


I am lost on what to do. I just installed this with a few other distros the same way I tried it with FC4 and I had no problems, I never had any problems like this. What am I missing? Or does anyone think there may be another problem here? If so what should I do?

Thanks

By the way I installed the flash plugins without any problems

By the way I wanted to add that I installed the binary first, then I deleted that and installed the rpm.bin one. Same results on both.

I know it might sound stupid but you say that you write
Code:
/usr/java/j2re1.4.2_08/plugin/i386/ns4/libjavaplugin.so /usr/lib/firefox-1.0.4/plugins
Doesn't that make a link called plugins instead of a link in the folder /usr/lib/firefox-1.0.4/plugins.
I would say that you should try
Code:
/usr/java/j2re1.4.2_08/plugin/i386/ns4/libjavaplugin.so /usr/lib/firefox-1.0.4/plugins/
instead.

I see what you mean. But writing it either way gets me a symbolic link in the firefox plugins folder. It just doesn't want to work.

First off, anytime you install a new version of an OS you really should read the release notes for that version, Had you read the release notes, you would have found Fedora's recommendation for Java. Here is a direct quote from said release notes:

Quote:
6.1.8. Java Package Recommendations

Fedora Core 4 users are advised not to use the Java RPM provided by Sun. It contains Provides that conflict with names used in packages provided as part of Fedora Core 4. Because of this, Sun Java might disappear from an installed system during package upgrade operations.

Fedora Core 4 users should use either the RPM from jpackage.org or manually install the Sun Java tarball into /opt. Sun Java 1.5+ is recommended for stability purposes.
It says to use Sun Java 1.5+, to use the bin file not the rpm, and most importantly you now need to install Java in the /opt directory, not the /usr directory as before. You then end up with a link such as:
ln -s /opt/java/re1.5.0_01/plugin/i386/ns7/libjavaplugin_oji.so

I did everything as stated in the release notes, and still had problems. The only way I can get Java to work, is to disable SELinux. As root, and you have to use su - not just su, enter the command
setenforce 0
and that will temporarily (until next boot) disable SELinux. Java will then work for me. Issue the command
setenforce 1
and turn SELinux back on, and Java stops working.

Hope that helps.

Wow. So everytime you boot Fedora you have to disable SELinux. That sounds a bit irratating. I never had any problem with any other distro, including BSD with Java like that. I think I may just wait on Fedora for now. It has some great points but I am busy with other things and I don't feel like having to disable whatever everytime I boot. I wonder if that is the only problem they have. Well right now I am having a ball with PC-BSD so I think I will get back to that. Thanks for the reply.

Try using the jdk 1.5.0_03, unless you really have to use the 1.4.2
Also, avoid using the rpm file, a lot a people seem to have problems with it. Use the bin executable which is also directly available for download.

Oh and by the way, if you have a /i386/ns7 folder down in the jre, use the libjavaplugin_oji.so that is there, instead of using the one under ns61.

Like I said above, there was a thread going around, not even sure it was in this forum but this is what I ran and my Java works fine now

[root@darco /]# alternatives --config java

There are 2 programs which provide 'java'.

Selection Command
-----------------------------------------------
* 1 /usr/lib/jvm/jre-1.4.2-gcj/bin/java
+ 2 /usr/lib/java/jre1.5.0_03/bin

Enter to keep the current selection[+], or type selection number: +

I cant explain exactly what occured but Java works fine now

To turn selinux off, not just temporarily, edit:
/etc/selinux/config

just change SELINUX=enabled to SELINUX=disabled

Personally, I get "permission denied" when I try to log in with selinux enabled, including with the root account:P
