On the octave ML top-posting is not preferable, please use the bottom-posting.
(See http://en.wikipedia.org/wiki/Posting_style)
This is a custom in the octave ML. 
When in Rome, do as the Romans do.


s = javaObject ("java.lang.String", "Hello OctaveString")


worked for me on octave 4.0.0 on windows 7.

*****************************
>> s = javaObject ("java.lang.String", "Hello OctaveString")
s =

<Java object: java.lang.String>
