How to verify all bindings for a callback are all be used?

[kujunguo kujunguo <ku...@gmail.com>]

I defined a composite like this:

<component name="MyServiceClientComponent">
    <implementation.java class="com.ibm.was.sca.callback.MyClientImpl"/>
    <reference name="myService" target="MyServiceImplComponent/MyService">

            <callback>
                <binding.sca/>
                <binding.jms/>
                <binding.ws uri="http://localhost:8087/MyService"/>
                <binding.ws uri="http://localhost:8088/MyService"/>
            </callback>

        </reference>

    </component>

    <component name="MyServiceImplComponent">
        <implementation.java class="com.ibm.was.sca.callback.MyServiceImpl"/>

        <service name="MyService">
            <!--<interface.java
interface="com.ibm.was.sca.callback.MyService"/>-->
            <callback>
                <binding.sca/>
                <binding.jms/>
                <binding.ws uri="http://localhost:8087/MyService"/>
            </callback>
        </service>

    </component>

When I ran the test case for it, no error, but I have some question for it:
1) Do we need to declare both callback bindings in <reference> and
<service> elements?
2) How to verify all bindings take effect in my running?

The ability to define multiple bindings allows the runtime to pick the most
appropriate bindings when sending the callback message from the service back
to the client.

I don't think that all of the bindings will take effect but I'd have to go
and check the code to see which one will be chosen. I suspect it will just
pick the first one that matches between service and client, in this case
binding.sca
