Interesting... eix is nice, but apparently not perfect. If I search 'eix
java', neither blackdown nor Sun comes up (no jre's, actually). But a
search of 'eix jre' produces:

Found 5 matches
which correctly shows that I have both the blackdown and Sun Java
runtime environments installed.

Here's one way of checking:
# export
<snip>
declare -x JAVAC="/opt/blackdown-jdk-1.4.2.01/bin/javac"
declare -x JAVA_HOME="/opt/blackdown-jdk-1.4.2.01"
declare -x JDK_HOME="/opt/blackdown-jdk-1.4.2.01"
$ export
<snip>
declare -x JAVAC="/opt/blackdown-jdk-1.4.2.01/bin/javac"
declare -x JAVA_HOME="/opt/sun-jre-bin-1.5.0.03"
declare -x JDK_HOME="/opt/blackdown-jdk-1.4.2.01"
So as you can see, the exported variables for root and the user are
different, at least as far as what Java VM are being used-- I don't have
the Sun JDK installed, but only the Blackdown, so that's correct too. It
doesn't seem to make any difference for the Java executables I've used
so far.
The idea being, 'export' without parameters will give you a list of the
current environment variables in use and their state. Of course, in this
case, you could just do a 'java-config -f' for both the user and for
root, to confirm what VM each one was using.
Hope this helps,
Holly
