What's your concern of the dependency? From OSGi perspective, there is no
Tuscany SCA API dependency. You just code your OSGi application following
the Remote Services using the standard and SCA related (in the effort of
being standardized) properties. Tuscany SCA is the Remote Service Admin
implementation behind the scene and it is transparently to OSGi users.
There are a few samples that would help you:
http://svn.apache.org/repos/asf/tuscany/java/sca/samples/dosgi-dynamic-calculator/dosgi-calculator.png
http://svn.apache.org/repos/asf/tuscany/java/sca/samples/dosgi-dynamic-calculator/
http://svn.apache.org/repos/asf/tuscany/java/sca/samples/dosgi-dynamic-calculator-operations/
In SCA, the protocols (bindings) and QoSs (policies) are declarative. The
Tuscany runtime is highly composable and extensible and you can decide which
bindings/policies should be enabled/included. Tuscany already has a rich set
of bindings, including Web Service, RMI, JSONRPC, JSONP, ATOM, JMS, and EJB.
You can add your own if yours is not there. BTW, Tuscany has a databinding
framework that supports various databindings out of the box, such as JAXB,
SDO, DOM, AXIOM, and JSON. The framework handles data transformations
automatically based on the source/target data types.

We already have the RMI support. In fact, the samples above use RMI to
connect the calculator and its operations.

Just for completeness. In CXF you can also plug in custom data bindings.
E.g. the CXF-DOSGi project also supports an alternate XML over REST (JAXRS)
databinding. I'm sure other data bindings could be added, if there's
interest in that.
Best regards,
David

Hi Raymond,
Thanks for the update, it's clear now. I resume my tests and investigation to migrate from JEE to OSGi.
Thanks again,
