Too soon... I forgot the very obvious options:

- Are you sure the Java package is loaded at all?
If you do (in Octave)
   pkg list

do you see in the output (possibly after scrolling down) a line like:

:
                java *|   1.2.8 | 
...\Octave\Octave-3.6.2\share\octave\packages\java-1.2.8
:

(line wrap!)
i.e., with the asterisk after the package name?
If not (when you don't see the asterisk) you should do (in Octave)
   pkg load java

and try again.
