First, try to make scripts not reliant on the presence of the
JAVA_HOME environment variable.  It should be enough to simply invoke
"java" to get a JVM.

However, if you need it, simply wrap invocations to the scripts with
JAVA_HOME=/etc/alternatives/jre
which uses the alternatives system to point to the system-preferred JRE.
