Yep, I had the same problem.  Very frustrating.  First of all, the sun java
1.6.X has problems with libxcb, then icedtea applets do not display.  Grrrr.

My solution was a bit brutish, but I downloaded that latest 1.7 snapshot (which
is what icedtea is) from http://download.java.net/jdk7/binaries/

Then I ran the following script PLEASE EDIT FOR YOUR OWN PATHS to set it up for
the the alternatives and plug in.  It works for all java apps I've tried without
problems.  Oh yeah, the script is a modified script that the icedtea rpm uses
for it's postinstall.

And for the people who want to argue about "free" vs "tainted" software.  I just
want software to work.
