Tips for WebEx on 64-bit Fedora 15

Things are settling down now on my Fedora 15, and it is time to get WebEx working.  After a few Google searches, I came across instructions on using 32-bit Firefox on 64-bit Fedora.

I had WebEx working in my 64-bit Ubuntu installation, so I decided to not settle for a 32-bit hack. I didn’t get a good how-to going, but here’s some tips that might help:

First, get Java working. I have Sun’s JDK 1.7 installed. I am not sure the version matters. Open JDK or Sun’s JDK should work, and the 1.6 should be fine. From this posting, I found the command to link the Java plugin to Firefox:

sudo /usr/sbin/alternatives –install \
    /usr/lib64/mozilla/plugins/libjavaplugin.so \
    libjavaplugin.so.x86_64 \
    /usr/java/default/lib/amd64/libnpjp2.so 20000

For Chrome, I used this command:

sudo ln -s \
   /etc/alternatives/libjavaplugin.so.x86_64 \
   /usr/lib64/chromium-browser/plugins/libjavaplugin.so.x86_64

If this still doesn’t work, you can troubleshoot with these commands:

ls -l /usr/java/default/lib/amd64/libnpjp2.so
ls -l /usr/lib64/mozilla/plugins
ls -l /etc/alternatives/libjavaplugin.so.x86_64

Now, make sure this page comes up and says that the Java plugin is working:
Java.com: How do I test whether Java is working on my computer?

If that works for you, move on to WebEx:
WebEx Join Test

Update: Unfortunately, while the Join Test works, it is not a good test. The 64-bit will not work with Desktop Sharing. If you plan to try to view someone’s desktop, you will need to fall back to the 32-bit version of Firefox and Java. You can view the requirements here, and notice that 27.27 has updated to requiring 32-bit.
