I noticed that macports has a java package available, and you're running 
Octave-3.6.4 installed via macports.  Any reason you don't want to install the 
java package from macports?

        sudo port install octave-java

There is an open bug report that doesn't bode well for you goal.

        http://trac.macports.org/ticket/30866

I tried installing java package via macports, but java_invoke.m is not present 
... is it supposed to be?

Regarding building the java package yourself, have you tried the "-local" flag?

Regarding the version of java, I have 1.6 installed.

        $ java -version
        java version "1.6.0_51"
        Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-11M4509)
        Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-457, mixed mode)
