hello,

i've just tried it and realised it had already been installed as a jdk* 
dependency. :)

however, according to the man page, running the following should select 
the most native and up-to-date version of java:

$ java -version
java version "1.4.2-p8"
Java(TM) 2 Runtime Environment, Standard Edition (build 
1.4.2-p8-root_21_jan_2006_21_32)
Java HotSpot(TM) Client VM (build 1.4.2-p8-root_21_jan_2006_21_32, mixed 
mode)

however, i've got newer version installed too:

$ cat /usr/local/etc/javavms
/usr/local/jdk1.5.0/bin/java # FREEBSD-JDK1.5.0
/usr/local/jdk1.4.2/bin/java # FREEBSD-JDK1.4.2
/usr/local/linux-sun-jdk1.4.2/bin/java # Linux-Sun-JDK1.4.2.10

how come 1.5.0 wasn't selected in the example above please ??

cheers,

martin
