Jre not working in Fedora
I am having trouble getting my jre to work. I have uninstalled and reinstalled it several times but that is not working. I have setup the firefox symlink.

Code:
sudo ln -s /usr/java/jre1.7.0_21/lib/i386/libnpjp2.so

I have tried to follow these instructions.

http://www.mjmwired.net/resources/mj...-f19.html#java

I have checked here several times. The box just stays grey and nothing happens.

For starters your symbolic link command syntax is invalid.

You need to give us more information if this forum is going to be able to help you. Are you trying to install OpenJDK or Oracle java? What version of Fedora? 32bit or 64bit? Did you try use the alternatives command?

The oracle java. This is the version I installed.
jre-1.7.0_45-fcs.i586
Fedora 15
32 bit

Is this what you are talking about?

Code:
sudo /usr/sbin/alternatives --install /usr/bin/java java /usr/java/default/bin/java 200000
sudo /usr/sbin/alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so \ libjavaplugin.so /usr/java/default/lib/i386/libnpjp2.so 200000

Someone on another forum mentioned this. I am not seeing what I would expect.
Code:
[bob@hi plugins]$ alternatives --config libjavaplugin.so 

There are 2 programs which provide 'libjavaplugin.so'.

  Selection    Command
-----------------------------------------------
   1           /usr/lib/jvm/jre-1.6.0-openjdk/lib/i386/IcedTeaPlugin.so
*+ 2           /usr/java/default/lib/i386/libnpjp2.so

Enter to keep the current selection[+], or type selection number: 
failed to create /var/lib/alternatives/libjavaplugin.so.new: Permission denied
[bob@hi plugins]$ rpm -qa | grep -i jre
jre-1.7.0_45-fcs.i586

I doesn't mention anything similar to this jre-1.7.0_45-fcs.i586.

I forgot to mention I have tried to get the oracle JRE to work in Firefox, Seamonkey, and Chrome. Are there any other browsers that it would be a good idea to try oracle JRE in?

I have forgotten most of my Java knowledge as i have purposely avoided Java for a number of years.

However your exception handler output looks like Java's CLASSPATH is not set up correctly or the requisite jars are not available on your system.

If again reinstalling try this and let me know if its helpful

Download Java from here
