Great to hear thats its running now (at least to some extent :).  Thanks
for your effort in eliminating all the other possibilities!

I usually check if the plugin is working correctly by using some of
the applets you can find in /usr/local/jdk1.5.0/demo/applets.  There
are also applet versions of SwingSet2 and Java2D installed in the demo/jfc
subdirectories that you can try.

The attached two patches should make XToolkit the default (they were
recently posted to freebsd-java).  If you or someone else who had the
same problem could recompile jdk15 with them and verify that you then
don't need to set the environment variable that would be great.
