It depends on what you want to exchange. Making java code to access octave data directly is not possible, because octave C++ data is not part of the java-managed memory space. You need to do some conversion; the java package provides the functions box/unbox to convert the basic types (strings, scalars, and even matrices [using the Matrix.java class]). Any octave object that cannot be converted (struct, cell array) is stored internally by the java package code, and given to JVM as an OctaveReference object. If you want to make the octave code able to access the Java data, you can do this using the java package (through the octave_java C++ class, which acts as a "reference to a java object" that can be manipulated from octave).
