extract common members from two classes

Hi,

What is the easiest way to extract common members from two classes into new superclass?

For example, I wont turn:

class A {
   pirvate String fieldName;
   private String someOtherA;
   //getters/setters here
}


class B {
  private String fieldName;
  private String someOtherB;
   //getters/setters here
}


into:

class Basic {
     private String fieldName;
        //getters/setters here
}

class A extends  Basic {
  private String someOtherA;
      //getters/setters here
}


class B extends  Basic {
  private String someOtherB;
  //getters/setters here
}


?

I tried to select both A and B in project tree and then Refactor->Generify, Generify Obejcts, but it doesn't see any common fields.

Best regards, Eugene.
