jdks available on freebsd

[Simon IJskes]

Hoi,

What jdk's are supposed to work on freebsd1? I'm trying if river will 
run on freebsd, but latest-1.6 gives the following:

[trunk] $ /home/hudson/tools/ant/latest/bin/ant hudson-qa
Error: JAVA_HOME is not defined correctly.
  We cannot execute /home/hudson/tools/java/latest1.6/bin/java

I haven't set JAVA_HOME.

Gr. Simon
