After rummaging around I came across a missive
from a FreeBSD luminary claiming to have "fixed"
java selection on FreeBSD but alas
no explanation as to what the fix was.

  /usr/pkg/java/sun*/bin/java -version
gives me ...
java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03)
Java HotSpot(TM) Client VM (build 1.5.0_07-b03, mixed mode, sharing)


There is a file ...
/usr/pkg/openoffice.org2.0/share/config/javavendors.xml

that looks like it is the criteria that openoffice is using to
determine the installed java environment.

but this doesn't seem to match up ....
