I know of at least two cases that use the dot notation without classdef in
Octave 3.6.4:

pkg load java
x = java_invoke("java.lang.System","currentTimeMillis")
x.toString
clear x

pkg load windows % windows only I suppose
shell=actxserver('Shell.Application')
shell.MinimizeAll()
delete(shell)
clear shell

I think classdef is the only way to create things that use the dot notation
within the octave language. AFAIC this does not apply to classes/objects
created in other languages including mex/oct files.
