OK, so in my fervor to delete IcedTea, I "yum erase"d java.
So, to get java back, I did the following:
# yum groupinstall Java
I could not locate the libjavaplugin_oji.so file, so I installed the jre as follows.
# yum localinstall --nogpgcheck jre-6u22-linux-i586.rpm # ln -sf /usr/java/jre1.6.0_22/plugin/i386/ns7/libjavaplugin_oji.so \ /usr/lib/mozilla/plugins
However, when I ran the Java test at ... http://java.com/en/download/help/testvm.xml
... I got the following error.
"Something is wrong. Java is not working."
I discovered that ps says java is not running.
# ps aux | grep -i java root 8986 0.0 0.0 4468 740 pts/3 S+ 18:31 0:00 grep --color=auto java
OK, so I created the following file, as recommended at http://www.fedorafaq.org/fc2/custom_java.html
# cat /etc/profile.d/java.sh export JAVA_HOME="/usr/java/jre1.6.0_22" export JAVA_PATH="$JAVA_HOME" export PATH="$PATH:$JAVA_HOME/bin"
Logged out, logged back in, still no joy. Got the same error message at the java test site.
Once again, any help would be greatly appreciated.
Here are some directory listings.

ln -s /usr/java/jre1.6.0_22/lib/i386/libnpjp2.so (be sure to have same version as shown)
To get correct link do a "locate libnpjp2.so"
This is the link you want in /usr/lib/mozilla/plugins. And take out any
libjavaplugin_oji.so link you may have in /plugins

I'm going to guess that perhaps your instructions are out of date?
First remove any unnecessary symlinks you created.
Fix icedtea: # yum install java-1.6.0-openjdk java-1.6.0-openjdk-plugin
Install Oracle/Sun Java: # rpm -i jre-6u22-linux-i586.rpm
Make it the system default: # alternatives --install /usr/bin/java java /usr/java/default/bin/java 20000 # alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so \ libjavaplugin.so /usr/java/default/lib/i386/libnpjp2.so 20000
To switch between IcedTea and Oracle/Sun (if necessary): # alternatives --config java # alternatives --config libjavaplugin.so
If you require path variables like $JAVA_HOME, make sure to use the softlinked paths (eg. /usr/java/default/bin) instead of a hardcoded version path. Helps when you update/upgrade.
If you have SELinux issues, might want to read this: https://bugzilla.redhat.com/show_bug.cgi?id=628031
These steps seem to cause minimal interference with Fedora and any Java related dependencies.
Hope this helps.
