Unable to send a list from Python to Java under SOAP with SCA

[ESSOUSSI Mohamed Habib <Mo...@telecom-sudparis.eu>]

Good day,

I am taking part on a project using SCA Architecture and Apache Tuscany 
(version 1.6.2).
The application includes 2 distributed components (in 2 different 
composites): The first one is implemented with Python language and the 
second with Java.
We noticed that we are unable to send a list of type String elements 
from the first component which is written in Python to the second 
component written in Java (ArrayList<String>) under SOAP protocol 
(binding.ws).
We recieve, instead, an inoperable complex type (like a tree) from which 
we could extract only the list's last element.
We would like to know if there is a way to send properly a list from a 
component written in python to be used as ArrayList<...> in a component 
written in Java?

Thanks in advance,

Yours,

Hi Mohamed,
I'm not familiar with Python so I can't give you a specific answer.
However, the general principle in SCA and Tuscany for sending any kind
of data from one language to another is to create a WSDL document with
a portType that defines a service interface using XML schema types.
You then need to generate language bindings from this WSDL document for
both the sending and receiving languages.  Have you done this?
