I'm not sure what you want as you didn't describe in sufficient detail what
you have tried yourself, so below is a bit of a guess.

If you need to invoke Java methods from Octave, you must add the directories
where these methods are (in .java files), and/or add the Java class libs
containing these methods (in .jar files), to the javaclasspath.
Before you can do that you'd need to load the Java package (" pkg load
Java").

Type (from Octave) "help javaclasspath" and "help javaaddpath" for more
info.

But if you want to invoke Octave from Java, you need another strategy.

In more detail,

gui.java has only the user interfaces required, which has a couple of canvas and button objects. The user provides input parameters and images in the java file. these inputs are to be passed over to octave, when the user clicks a button called 'process'. the octave does the image processing and generates the output. this generated output has to be send back to java interface to be displayed by the user.

the java class files and the octave m files are to be bundled for distribution even on non-java, non-octave installed systems. i am assuming only jvm to be present on the client machine.
