I'd suggest installing java/javavmwrapper from ports.

Quoting from javavmwrapper/pkg-descr: "The Java VM wrapper provides a
convenient system for switching between different Java VMs.  It also
provides symbolic links in ${PREFIX}/bin to allow the use of the Java
executables without having to add the specific Java VM executable
directories to the PATH environment variable."


After installing, instead of changing symbolic links, all you need to
do is to change the JAVA_HOME variable in a configuration file.  Below
is a snippet of my configuration using Diablo 1.5 and JDK 1.6.

[snip]
# JDK 1.6  (Currently commented, i.e. disabled)
#JAVA_HOME=/usr/local/jdk1.6.0
#JAVA_OS=native
#JAVA_VENDOR=freebsd
#JAVA_VERSION=1.6
#JAVAVM_OPTS=-XX:+UseThreadPriorities

# JDK 1.5 (The active JVM)
JAVA_HOME=/usr/local/dialblo-jdk1.5.0
JAVA_OS=native
JAVA_VENDOR=freebsd
JAVA_VERSION=1.5
JAVAVM_OPTS=-XX:+UseThreadPriorities

HTH,
