Java Woes - Req How to uninstall Java

Alfred · #1 4th March 2005, 01:30 PM

I am having the problems many are having with Java and Firefox. Quite simply Firefox shuts down as soon as it encounters a padge with Java. I installed Java using the instructions at http://fedoranews.org (...)/stanton_finley....

I have scoured the many posts on this and have concluded that I must uninstall it completely and reinstall using a different method?? synaptic??. However, can someone explain how to uninstall it? I don't want to bugger it up.

if you are using firefox instead of mozilla do

cd /usr/lib/firefox-X.X/plugins/ instead of /usr/lib/mozilla-X.X/plugins

ln -s /usr/java/jreX.X.X_XX/plugin/i386/ns7/libjavaplugin_oji.so

to uninstall :
do as root ( http://www.fedorafaq.org/basics/#root )

Code:

rpm -e j2re

and then install java this way : http://www.fedorafaq.org/#java
It is the same as if you would install it with synaptics.

Or do what my preposter said.

Not sure what this does and why (sorry but I am quite new to Linux). You are saying I should change directory to "/usr/lib/firefox-X.X/plugins/" and then create a symbolic link between what???

well at first i supposed that you have undergone a successful java binary installation. did you achieved up to here?
afterwards in order to add the java plugin to for firefox, fire up any terminal or your choice, change directory to
cd /usr/lib/firefox-X.X/plugins/
then create the symbolic link for the plugin with the cmd

Code:

ln -s /usr/java/jreX.X.X_XX/plugin/i386/ns7/libjavaplugin_oji.so

replace X.X with the version number

this means that the file libjavaplugin_oji.so will have a shortcut in the directory /usr/lib/firefox-X.X/plugins/

Okay I tried creating the symbolic link but it still wouldn't work

I then did "rpm -e j2re" to uninstall Java.

Following that I tried to get the installation of Java via the www.fedorafaq.org/#java. I replaced my yum.conf with his yum.conf, then attempted to do the following:

Code:

[root@localhost etc]# yum --enablerepo=dag install j2re mozilla-j2re
Error getting repository data for dag, repository not found

As you can see the result was unsuccessful. Can anyone help?

chech whether your /etc/yum.conf has this lines:

Code:

[dag]
name=Dag APT Repository
baseurl=http://dag.freshrpms.net/fedora/$releasever/en/$basearch/dag/
  http://dag.atrpms.net/fedora/$releasever/en/$basearch/dag/

No help in solving your problem, I'm afraid. Just letting you know my experience is just the same. I've tried the modified symlink, I've uninstalled and re-installed,(download and rpm style) and re done the symlink. Same result.

Okay this is driving me crazy. I installed the jre using

Code:

yum --enablerepo=dag install j2re mozilla-j2re

That worked after I fixed my buggered-up etc/yum.conf. The installation was apparently successful as it said "Completed!". However, now I am tying to sort out this symbolic link stuff. The problem is that I checked /usr/java and the directory is empty! If it installed shouldn't there be something there?

I use Firefox 1.0.1

You don't need it anymore.
Try to use firefox now, without setting theis symbolic link!

I tried it. I even ensured that I deleted the symolic link that was in the firefox plugin directory

However I still get firefox closing immediately as soon as I encounter a java applet. I don't even need java in Firefox - the problem itself is just bothering me! This must be a bug but I can't beleive that the problem can't be isolated. Some users appear not to have this problem. Could it be kernal related? ... only one way to find out.
