    Question Problem with Octave and Java

    I have installed Octave (from repos) for the first time. I also installed the Java API package.
    When I run octave from terminal, here's what I get

    Code:
    warning: timestamp on file /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so is in the future
    error: java_invoke: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so: failed to load: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server/libjvm.so: cannot open shared object file: No such file or directory

    The problem is it is looking for OpenJDK whereas I use Oracle Java. JAVA_HOME is correctly set to /usr/lib/jvm/java-7-oracle, so is PATH.

    So how can I tell Octave where to look for JRE and/or JDK?

    Thanks

    Look in here : http://wiki.octave.org/Java_package#...e_to_Octave.3F
    ( I am using this wiki page for more elemental actions and find it very useful , this java chapter seems exhausive)
