I'm very confused as to what you're doing. Why were you trying to use
Jython when you knew it wouldn't work "because of the absence of Ctypes
modules in it"? Note that STAX uses Jython 2.1.
In regards to directing you to actual STAX jobs, we provide several STAX
jobs (.xml files) in the libraries and samples directory when you extract
the STAXVxxx.zip/tar file. They are "real" STAX jobs that do real
things.
Many people don't leverage any of Jython's capabilities. They simply use
the <process> element to run their testcases (which may be written in any
language) on whatever machines in parallel (e.g. via the <paralleliterate>
element or sequentially). Jython is merely the scripting language that
STAX uses for variable and expression evaluation. STAX uses the Python for
variable and expression evaluation. You don't have to exploit any of
Jython's capabilities, though you can if desired.
How each test team writes their STAX jobs is completely up to them. I
don't have access to other test team's STAX jobs.

Importing a Jython module and running it via a <script> element runs it
within the same Jython interpreter as the STAX job. You can have your
Jython script return whatever you want (e.g. return 'pass' or return
'Failed with xxx'. So that it could return an indication of the test
status which you can assign to a variable such as "testOutput" and then
check it to determine if the test passed or failed. For example:
<testcase name="'Test1'">
<sequence>
<script>
testOutput = FreqAndLevelTest()
</script>
<if expr="testOutput == 'Success'">
<tcstatus result="'pass'"/>
<else>
<tcstatus result="'fail'">testOutput</tcstatus>
</else>
</if>
</sequence>
</testcase>
If you really neededto use a <process> element instead to run your test,
perhaps because you need to run the program on a remote machine, you could
do this instead as I'll talk about next.
Is there a reason why you're using Jython to call the java programs that
test your APIs instead of just running a Java program (or programs)
directly to test your APIs via a <process> element? For example:
<process>
<location>'local'</process>
<command mode="'shell'">'java Test'</command>
<stderr mode="'stdout'"/>
<returnstdout/>
</process>
If there is a good reason why you're using Jython instead of Java
directly, you could run a Jython script via a <process> element on a
machine if Jython is installed and accessible in the path, or you can
fully qualify the path to the jython executable, on the machine where the
process is run. Also, your Jython script must provide a main() function
and check if the __main__ top level module is called and have it call the
main() function in order to handle being run as a program. To run a
particular function in your Jython script, you would need to modify your
Jython script to accept a argument by having it's main() function check
the argument(s) passed in. See Python documentation such as
http://www.artima.com/weblogs/viewpost.jsp?thread=4829 for more
information on the main() function and on passing arguments to it. You
don't import the Jython module in this case as you are running the Jython
script in a separate program. Here's an example of running a Jython
script via a <process> element:
<process>
<location>'local'</process>
<command mode="'shell'">'jython C:/tests/test1.py'</command>
<stderr mode="'stdout'"/>
<returnstdout/>
</process>

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
