Hi Tony, Thank you pointing out this package it can be an answer to my problem except that it does not handle with external JVM (we packed oracle java7 for squeeze here) or it need some tweak in /usr/lib/java-wrappers/jvm-list.sh. Does my proposition lead to problems I am not aware of ? (that could avoid workaround like java-wrapper thing also) Cheers -- Damien HARDY
