create custom java object from octave - ClassNotFoundException

I have written a simple custom java class

public class Optim {

public int optfunc(int x1, int x2, int x3, int x4, int x5, int x6)
{
    return (x1^2 + x2^2 +2*x3^2 + 2*x1*x2+x1*x3-200*x1- 140*x2 + 120*x3+200);
}

}

Now I want to create an object of type Optim in Octave. I have created a file called javaclasspath.txt which contains only one line

C:\Users\Sorin\Optim.class

and put this file in C:\Users\Sorin along with the file Optim.class When I start Octave I can see the following

>javaclasspath
STATIC JAVA PATH

  C:\Users\Sorin\Optim.class
  C:\Users\Sorin\Optim.class
 DYNAMIC JAVA PATH

  - empty -
>pwd
ans = C:\Users\Sorin
>x = javaObject('Optim')
error: [java] java.lang.ClassNotFoundException: Optim

Do you have any idea why the class is not found? Thank you in advance.

The class path needs to contain the directory where your .class file lives. Not the .class file itself.
