Unfortunately, I've set up nothing overt with respect to Java, so this is all I know about the java that is installed currently: $ java -version ==> java version "1.6.0_24" ==> OpenJDK Runtime Environment (IcedTea6 1.11.11) (rhel-1.61.1.11.11.el6_4-x86_64) ==> OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
