How to externalize the webservice reference URL?

[Melinamani, Sanjay]

Hi,
I like to externalize the webservice reference URL to a property file.
Example if I have the following composite, I like to read the URI from a 
property file since the URI changes from DEV to QA to PROD env. Let me know how 
this can be done?

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
                targetNamespace="http://helloworld";
                xmlns:hw=http://helloworld name="helloworldws">
    <component name="HelloWorldServiceComponent">
        <implementation.java class="helloworld.HelloWorldImpl" />
                    <service name="HelloWorldService">
                        <interface.wsdl 
interface="http://helloworld#wsdl.interface(HelloWorld)" />
                        <binding.ws 
uri="http://localhost:8085/HelloWorldService"/>
                    </service>
    </component>
</composite>

Thanks
Sanjay
