RPC between SCA components

Basic RPC style operations between SCA components using the JMS binding.

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
           targetNamespace="http://sample"
           xmlns:sample="http://sample"
           name="HelloWorld">

    <component name="HelloWorldClient">
        <implementation.java class="helloworld.HelloWorldClient"/>
        <reference name="helloWorldRef">
            <binding.jms uri="jms:HelloWorldService"/>
        </reference>
    </component>

    <component name="HelloWorldServiceComponent">
        <implementation.java class="helloworld.HelloWorldServiceImpl" />
	<service name="HelloWorldService">
            <binding.jms />
        </service>
    </component>

</composite>

One component exposes a JMS service on a queue named 'HelloWorldService' (based on the service name). Another component invokes the service by sending JMS messages to that queue (based on the configuration in the binding.uri). With this configuration messages are marshalled into JMS messages as XML text messgages. After processing at the service a temporary destination is used for the response message. Again the response messages are marshalled into JMS messages as XML text messgages. Exceptions?

The sample helloworld-jms shows this scenario working in full.
