Sharon,

The whole purpose of using Java is to load the dll and access its exported
APIs which at the moment Jython is unable to do because of the absence of
Ctypes modules in it. The ctypes is planned on its roadmap and is expected
to be out in a period of four to five months.

Had ctypes been available this time then also all the Tests had to be
written in Jython. With the idea of keeping the tests unchanged, I thought
of calling the dlls and its associated APIs from Java. This way my Tests
would need quite a less number of changes (to adapt them to using cytpes
when it is available) as opposed to writing them now purely in Java ( as you
pointed out) and then changing them to entirely in Jython (when ctypes is
available).

I have had a look at STAX User guides and Training manuals, but they all do
not deal with the real world test cases. Could you please direct me to some
useful sites where I can actaully see the Stax jobs, how they use Jython,
and how different people do different test setups. I think this would give
me more clarity and enable me to use the STAF/STAX to the fullest ( as we
are naive users and starting to implememt it on our organization).


I will work on your above post and will disturb you :o) again if in case I
have more to ask you on this.


Many thanks,


Cheers,
Rajat
